Do you know the real reason for the lithium battery performance degradation it?

Image
Li-ion battery has now been widely used in mobile devices, but the battery life is not long, 500 charging cycles will lose about 1/5 of capacity.   In order to study the reasons for the lithium battery degradation, the US Pacific Northwest National Laboratory scientist using a powerful microscope to observe the success of the real-time status of the lithium battery charge and discharge. The researchers found that when using the battery creates pressure and cause rupture electrode.   In addition, for each charge and discharge cycle will leave traces of lithium electrode in addition to these "death" of lithium which can no longer play a role in the future of charging, and will cause a decline in battery capacity.   The researchers also observed in the solid electrolyte interphase layer is formed on the electrode surface, which can "clog" the battery and affect its ability to charge. Lithium who want to solve these problems, the use of alternative methods is o

Battery Tests Show Some Lithium-Ion Cells Last Over 5x Longer

Image
Researcher Andreas Gutsch from the Karlsruhe Institute of Technology said at the PV Symposium in Germany recently that some lithium-ion cell s working in storage systems experienced up to 30% capacity loss after 1,000 cycles, while some cells have a better capacity after 5,000 cycles. In other words, there can be quite a lot of variation in lithium-ion cell performance. lithiumionbatteryger Testing conditions did not allow him to reveal the names of cell manufacturers. The cells were not easy to obtain for testing and he could not disclose that specific information. However, his test results did reveal that cells from China that were tested had the performance that decreased most rapidly. Cells from Japan and Germany did the best, while ones from South Korea and the US were in the middle of the performance range. One battery type that was specifically mentioned was the Tesla battery. This battery was found to last 400 cycles and was indicated to have the ability to power a car for a

China's BYD ramps up 'leccycar battery production in challenge to Tesla

Image
Warren Buffett-backed Chinese car manufacturer BYD is aiming to compete with Tesla Motors by tripling its production of batteries for electric cars over the next three years. BYD will produce an additional six gigawatt-hours' worth of batteries per year over the next three years, said company spokesperson Matthew Jurjevich, adding that with the support of consumer demand these production increases could be continued beyond the three years of increase scheduled. If this rate of production increase continues to 2020, BYD would be set up to challenge Tesla Motors' $5bn Gigafactory in Nevada, which is projected to achieve an annual production capacity of 35GWh when it begins operating in 2016. Rumours of difficulties in the development of the Tesla Gigafactory have been refuted by CEO Elon Musk. The company is, however, downsizing its Chinese operations following a bungled incursion into the market which has left its distribution centres overstocked. Tesla does not currently pro

About the past era of lithium aluminum battery age will come up?

Image
Chinese American scientists have developed a high-performance aluminum battery's first commercial application, its charge faster, last longer and very cheap, just one minute using this smart phone battery is fully charged. The new battery can replace the widely used but there is still insufficient lithium ion batteries and alkaline batteries. Research published in the April 6 issue of "Nature" magazine online edition. Because aluminum battery has a low cost, easy to burn and do not have a high charge storage capacity, etc., for decades researchers have attempted to develop an economically viable to aluminum ion batteries, but has not been successful, where the key challenge is to find the right positive materials and electrolyte materials, so that the aluminum battery is constantly charging and discharging cycles can still produce an effective voltage. The study's lead author, professor of chemistry at Stanford University Dai said: "People try a variety of cath

Power lithium battery high demand in 2014 will meet the explosive growth of the future

ufo battery offical site 2014, the number of new cars in the global energy yield sales USA, China, Japan, the European Union and other countries and regions, led by more than 300,000, only China's new energy vehicle production in 2014 reached 83,900. The rapid development of new energy automotive industry, so that the global growth in demand for lithium battery power significantly. According to statistics, in 2014 the world's lithium-ion battery shipments reached 10012.8MWH. Recalling 2014, AESC, BYD and LG lithium battery shipments over 1GWH, to become the world's top three manufacturers of lithium battery. In 2014, about 800MWH Panasonic lithium battery shipments, SDI, LEJ, Hefei, China Xuan and other enterprises Air lithium lithium battery shipments ranking. AESC batteries which are mainly supplied to the Nissan LEAF and the Renault Kangoo ZE, 24AH batteries using NCM ternary system; LG major supplier to the Chevrolet Volt, Renault ZOE, Volv

LG Chem will provide the lithium battery cell Daimler Smart EV

Image
K-car News LG Chem has released an official statement saying that Daimler has selected the company as a supplier of lithium batteries , will provide Smart EV battery, which models will be launched in 2016. LG Chem will provide Daimler cell, battery pack assembly by Daimler. Last August, LG Chemical also received orders for Audi's battery, which provides support for plug-in hybrid vehicle lineup. The company also noted that the future is expected to get more orders from Audi's parent company Volkswagen Group. In the field of automotive batteries, LG Chemical has gained 20 customers, including General Motors; the company's goal is to overall sales in 2018 will increase to a large battery of 10 trillion won (US $ 9.8 billion) or more.

1, Note the signal strength One culprit   phone battery   consumption is often quick search weak signal, but for us, but there is no way. If you are in a relatively poor signal areas, consider temporarily switch to flight mode, not iPhone constantly searching weak signal. Also Wi-Fi can be used under the conditions as much as possible with Wi-Fi, cellular data equally unstable cell phone battery will bring relatively large consumption. 2, closed useless notification center applications Many applications in the notification center will continue to push the message that you really need it? I think most people are not yes. Each application will consume little power push notifications, so we have to cut off the source. To "Settings", "Notification Center" go close it, and do not forget to turn off the sound alerts and icon. 3, change the display settings Display is power-hungry, and therefore do not have the time necessary to make it fast closing.
