Ultra High Energy Density Lithium-ion Cylindrical Battery

High energy density, single battery energy density of 220Wh / kg or more, by cell materials and battery systems design solution enables high-energy quantization 18650 battery, including:

High specific capacity high nickel cobalt manganese lithium nickel or nickel-cobalt-aluminum material lithium cathode material and high specific capacity artificial graphite or silicon-carbon anode materials; and the development of adaptation with a high voltage for a silicon negative electrode and an electrolyte electrolyte materials, battery materials through system integration and optimization, to improve battery energy density and good cycle stability, improve the cost-effective use of 18650-type battery;

Reducing the thickness of the positive and negative current collector; to solve the battery safety problem by coating the negative type collector, reducing non-electrochemically active material while ensuring battery safety performance, taking into account the electrochemical performance and safety to meet the electric car the need to use;


Optimization of cell structure, reduce the amount of conductive agent and a binder, the amount of the membrane, reducing the mass and volume of the electrochemically active material of the battery Central Africa, to improve the energy density of the battery.

December 26, 2014, the US electric carmaker Tesla released an updated version of the discontinued two years ago, the first generation model Roadster, the mileage of 644 km, 60% higher than the original.   Advances in battery technology to enhance the performance of the Tesla product, after Roadster Mileage is 393 km. Tesla CEO Musk said Tesla high-performance graphene battery, compared to the current capacity increase of nearly 70 percent. British scientists have invented graphene after 10 years, the application of the battery with great breakthrough. In early December, the Western media reported that Spain and the Spanish company Graphenano Cordoba University to develop graphene battery, a charging time of just eight minutes, can travel 1000 km. It is graphene researchers called "super cell." "We still understand the situation, the specific situation in Spain is proving such a battery, if this is confirmed, it is indeed a revolutionary c

Solar Energy Storage Battery Technology Get a Revolutionary Breakthrough

Image
When natural gas, coal, oil and other non-renewable resources, frequent emergency, energy is increasingly becoming a bottleneck for social development, the solar,wind and other renewable resources has become a new driving force for economic development. At the G20 summit, renewable energy issues, environmental issues will become the object of world leaders concerned, and as the organizer of China is more practical action to demonstrate its adherence to the concept of environmental protection,  solar power energy storage  technology also achieve a breakthrough, and further summit environmentally friendly match. Solar energy battery storage in the near future will occupy an important position in the world energy consumption, not only to replace part of conventional energy sources, and will be the subject of the world's energy supply. By 2030, renewable energy in the total energy mix accounted for more than 30%, while the proportion of solar battery storage in the world's tota

In addition, energy storage research also has multiple problems, such as foam cells, flow batteries to a variety of chemical materials, no one knows which technology will attract the most funds and research heat. Lux Research reports that the energy storage investment of more than 40 billion US dollars,  such as  solar power generator  and wind power,  the development of next-generation batteries, non-lithium-ion battery startups in the past eight years, an average of only 4 million funds, Tesla investment in lithium-ion battery factory Gigafactory invested 5 billion US dollars . R & D new battery material threshold is very high, just to build a small production line to study the details into production, it is necessary to 500 million US dollars, car manufacturers may also take several years to test the new battery system before deciding whether to purchase, if Your company has only $ 5 million in capital a year, making it hard to invest $ 500 million in manufacturing.
