Li(NiCoMn)O2 lithium Era, Chinese Enterprises How to do?

According to a survey in 2014 showed that the development path from the electric energy, the hybrid is not around the last stage in the more distant future, electric cars can become mainstream route, the most critical is to see mileage can follow up. To enhance the pure electric car Mileage solve mileage anxiety, there are many ways, such as the vehicle's weight, more intelligent battery management system, but the most fundamental, or in the battery itself.

January 24, in the new global energy vehicles on the General Assembly in Tianjin to have a battery-themed salon. From the 18th Research Institute of China Electronics Technology Group Corporation, Henan lithium-moving power, Tianjin Lishen, Celgard (products for battery separators) and Boston battery power battery guests to development and technology options were discussed, and in this Sharon reflected in the pieces of information is very interesting.

Rise of LiNiCoMnO2 lithium battery

"Given the choice of lithium battery materials, the fundamental problem is. Greater energy density on energy density, better mileage solve the problem, then the other problems can be overcome."

This is the scene guests to answer when asked about what kind of lithium batteries become more mainstream. LiNiCoMnO2 in energy density lithium iron phosphate lithium relative has a natural advantage, but as technology advances, the security issues have been improved, the tendency within the industry is even more apparent.

Originally domestic battery in the power market, the mainstream is lithium iron phosphate batteries, lithium iron phosphate prices are relatively cheap, good security, large magnification, the charge-discharge cycle life better, is very suitable for the use of electric vehicles in China a few years ago the battery is also mostly gone the route of lithium iron phosphate. However, with the improvement of the ternary lithium battery safety issues, domestic battery manufacturers also began to tend to LiNiCoMnO2 lithium route.

Currently ternary material used is 1: 1 structure, the structure is more stable, more mature preparing ternary material types: 1. Currently ternary lithium production through the electrolyte and a special ceramic membrane technology. Ceramic membrane may be spaced a short circuit in the battery internal short circuit source, thereby significantly improving the safety performance of ternary lithium batteries.

After solving security bottleneck, ternary lithium batteries high energy density, low-cost advantage is revealed itself. Low energy density lithium iron phosphate, the greater the weight of the same capacity heavier volume, seriously affecting the electric car's battery life, while the ternary lithium much better.

In the discharge rate, although not as good as the ternary lithium iron phosphate lithium, but pure electric vehicle battery capacity, most of the electrical power is not too large, the case of high-rate discharge rarely reveal the obvious shortcomings.

In terms of life expectancy, ternary lithium iron phosphate lithium battery is better, but users tend to be more concerned about the initial purchase cost, and less attention to the replacement cost of the battery, and the battery industry trend watching, along with the expansion of production capacity, the price of lithium per year are on the decline, true to the need to replace the battery pack when the high cost may not be imagined.

Advantages and disadvantages shift. Beiqi new energy listed EV200 and ES210 two electric cars to give lithium iron phosphate line, for ternary lithium batteries. In the next period of time, LiNiCoMnO2 rise in power lithium battery market is irresistible. However, Dr. Xiao Chengwei from the 18th Research Institute, also said of the ternary lithium batteries are frequently raised, not only because of high energy density, but also because of its current development has matured, will reappear new future lithium battery type, and then the selection criteria is still the energy density, the number of high bidder.

Advancing international giant Chinese market

In this piece of battery power, Chinese enterprises should have and like other businesses, enjoying Chinese-made low-cost, competitive in price. However, with the new energy automotive industry is optimistic about the industry's giants eyeing China's battery market. Boston is one of the battery, which has factories producing batteries in Changzhou, Jiangsu province, and said it will focus on the Chinese market, increase productivity through cost-sharing approach, reducing the cost of lithium batteries.

International giants compared to domestic enterprises in advanced technology and equipment or to some. And its raw materials from domestic access (According to the site broke the news, and even some raw materials companies sold to foreign firms selling price is lower than the domestic manufacturers), the production base in the country, enjoy cheap Chinese labor and land taxes, and other resources, product prices even can even lower than domestic manufacturers.

And international giants behind strong capital support, not afraid of short-term losses, from a strategic point of view can play a very long period of price wars, which makes domestic enterprises are facing a serious threat.

Power battery industry is developing rapidly, although the overall plate small but great potential foreign giants already eyeing this market, Chinese manufacturers face challenges.

How to deal with used batteries?


Battery is one of the most commonly used in daily life goods, cell phones, cameras, alarm clock, doorbell, remote control, etc., are inseparable from the battery. "My family kept a festival than a dozen used batteries, fearing random throw will pollute the environment, but can not find collection points, how to do it?" Recently, who lives in the village of happiness Sun told reporters, do not know how to properly handle home used batteries.

Waste battery recycling bins Hard to Find

"You see, so many used batteries, how to do it? Threw fear pollution of the environment, do not throw it and do not know how to deal with, is really a problem." Speaking of the Sun a feeling annoyed.


According to Mr. Sun introduced a lot of used batteries at home, mainly from children's toys, remote control, razors and other battery models are on the 1st, 5th, 7th. Considering the used batteries will pollute the environment, Sun will be saved in a used batteries together, such as when the family went to the mall, directly to the battery into waste battery recycling bins inside the mall. But most recently, Sun found waste battery recycling bins in some shopping malls are gone, many people do not know where these batteries the throw.

Interview, the reporter learned that the Sun so there really a lot of public concern, many environmentally conscious people consciously collect used batteries, avoid polluting the environment cause harm to humans.


Batteries and cell phone batteries to be treated separately

It is understood that the State Environmental Protection Administration, the National Development and Reform Commission and other departments have issued the "Waste Battery pollution control technology policy" clearly states that the public commonly used 5, 7 disposable batteries do not need to be recycled, but rechargeable batteries and button-type batteries polluted heavy, must focus on recycling by the manufacturer, not the people carelessly throw away.
According to professionals, if it is generally on the 5th or the 1st battery can be processed directly and garbage together, focusing on the recovery of the nickel-cadmium batteries, nickel hydrogen batteries, lithium batteries, including mobile phone batteries, rechargeable batteries, batteries, car electric vehicle batteries (bottles) and the like. If the people have such a waste battery recycling and the manufacturer can contact, or contact the environmental protection department. Another public buy time to see whether the battery "mercury" logo.

When reporters visited the market learned that many big brands are marked "mercury-free alkaline battery" or the word "mercury-free super-carbon batteries" on the battery packaging, while the surface of some cells did not otherwise specified . According to state regulations, if there will be green, "China Environmental Label" on the battery packaging, which is through the Environmental Protection Department of Environmental Certification Center of the mark, with the logo of the battery is generally considered to be environmentally friendly batteries, these batteries can be used and garbage into the processed together.

In addition to household waste batteries directly with household waste, but the reporter also learned that in life there are many recycling of batteries is a must. Such as electric vehicles commonly used lead-acid batteries, used in laptops and other nickel-cadmium batteries must be recycled, we can consult the electric car and computer vendors.

The public is best not to arbitrarily destroy dry appearance package, otherwise easily lead to electrolyte leakage and corrosion around the items. Such as alkaline batteries, the battery electrolyte with a strongly basic electrolyte; another example lithium batteries, the electrolyte solution contains an organic solvent. In addition, waste batteries if flooding over, there will be some contamination, be careful not to just throw the battery farmland and humid place.

Expert and Inventor of the Lithium-Ion Battery Predicts That Within 10 Years, Every Vehicle Will Be Hybrid or Electric

Binghamton University Professor M. Stanley Whittingham is at the forefront of the movement to design the next generation of lithium-ion batteries. But that's nothing new for the man who holds 16 patents, is number 17 in the Greentech Hall of Fame and invented the technology 40 years ago.

Whittingham started his career strong, winning the Young Author Award from the Electrochemical Society in 1971 and quickly landing a job at Exxon, where he rode a wave of interest in alternative energy. It was the nation's first energy crisis. Drivers had to wait in line for hours to get gas, and industries and governments poured money into research. His team's mandate at Exxon was simply to explore energy sources other than petroleum.
He found one when he invented the lithium-ion battery. Today, it's the heart of just about every personal device — laptops, tablets, smartphones, MP3 players, etc.

The Basic Composition of Lithium-ion Battery and Main Materials


The basic composition of lithium-ion battery and main material, lithium-ion battery is a chemical power.

two electrodes cell redox reaction in progress, respectively, must be carried out in two separate areas, which is different from general oxidation-reduction reaction.

When two electrode active material undergo a redox reaction, the desired electron must be transferred from an external circuit, which is different from the micro-cell reaction corrosion process.

In order to meet the above conditions, no matter what the battery series, shape, size, by the following components: an electrode (active material), electrolyte, separator, binder, a housing; in addition to positive and negative electrode lead, the center terminals, insulating material, the safety valve, PTC (positive temperature control terminal) and the like are also an integral part of the lithium ion battery. The following briefly describes the lithium-ion battery in a few major components, namely the electrode material, electrolyte, separator and adhesives.

An electrode material

Is the core of the electrode of the battery, the active material and the conductive framework composition. Positive and negative active material is a source of generating electric energy, the battery is to determine the basic characteristics of an important part. As in lithium-ion batteries, the current commercialization of the cathode active material for lithium-ion batteries are generally LiCoO2, the current research focus is moving without cobalt material efforts, there are some on the market LiMn2O4 cathode materials used and so on.

Non-static electricity inside the power supply unit of positive charge is to move from the negative power supply circuit to the cathode through the internal process of the work done. EMF symbol is ε, in volts (V). Additional power is a form of energy into the electrical energy. To maintain a constant current in the circuit, only the electrostatic force enough, you also need to have a non-static electricity. Power is providing non-static electricity, the positive charge is moved from a low potential at the high potential of the non-electrostatic charge to promote the process of doing work that other forms of energy is converted to electrical energy in the process.

EMF is a physical quantity characterizing the power generating electrical energy. Different supply sources of different non-static electricity, energy conversion forms are also different. Such as chemical electromotive force (batteries, button batteries, batteries, lithium-ion batteries, etc.) is a non-chemical effects of static electricity, the size and power independent of electromotive force size; non-static electricity generator is the magnetic field of the moving charge forces; photo-electromotive force (photovoltaic cells) derived from a non-static electricity within the photoelectric effect; piezoelectric electromotive force (crystal piezoelectric ignition, crystal microphone, etc.) from the polarization caused by mechanical work.

When the external circuit power supply is disconnected, non-static electricity and electrostatic field strength inside the power supply balance, the positive and negative power supply voltage is equal to the electromotive force at both ends. When the external circuit is turned on, the terminal voltage is less than the electromotive force.

With less low prices

Second, the battery assembly process and technology

In accordance with the structural design and the design parameters of lithium batteries, how to prepare the material of the selected battery and efficiently together, and assembled with the design requirements of the battery, the battery production process is to be solved. Thus, the cell production process is reasonable, is related to the assembly of the battery is the key to meet the design requirements of the most important steps affect battery performance.

Reference AA-Cd / Ni, MH / Ni battery production process, combined with the AA-type lithium-ion battery design and performance characteristics, and repeated testing of lithium-ion battery materials, AA lithium-ion battery production process to determine .

AA lithium-ion battery production process involves four steps: preparing tablets
positive and negative; batteries winding; assembly; seal. This is the traditional AA-Cd / Ni battery production process is not much difference, but in the process, the lithium-ion battery is much more complex, and environmental conditions should be much more demanding requirements. Lithium-ion batteries are very strict manufacturing technology, require complex. The following table lists the graphite / LiCoO2 series cylindrical lithium-ion battery manufacturing process related parameters.

Wherein the preparation of the positive and negative electrode slurry, the positive and negative film coating, drying, rolling and other preparation, wound batteries greatest impact on cell performance, a lithium-ion battery manufacturing technology is the most critical step. These processes make the following brief introduction.

To prevent the lithium metal anode mass flow in parts of the copper precipitation caused by security issues, the need for process improvement pole piece, both sides need to use copper foil coated with carbon paste. The main steps of the process of lithium-ion batteries as follows.

positive and negative pulp with special solvents and adhesives were mixed with powdered active substances, even after a high-speed mixing, slurried positive and negative material.

coating the slurry was uniformly coated on the surface of the metal foil, drying, respectively made positive and negative tabs.

a diaphragm assembly according to the positive electrode sheet The negative electrode sheet put away in a sequence from top to bottom of a separator, a battery through the winding core, and then by injecting an electrolyte, sealing and other processes, i.e., to complete the assembly process of the battery, the finished products battery.

into with dedicated battery charging and discharging equipment for finished battery charge and discharge testing, for each battery are only for testing, screening qualified battery products to be manufactured.

From the design requirement, because the case is selected for 18650 lithium AA type (
14mm × 50mm), the cell structure design mainly refers to the size of the battery cover, the tightness of the battery assembly, the electrode sheet size, battery upper air chamber , the ratio of polar substances, such as design. Whether they are designed to directly affect the battery's internal resistance, internal pressure, capacity, performance, and security.
