The latest issue of the famous American financial magazine Barron's Weekly published an article signed by Bill Alpert, said Elon Musk, CEO of American electric car manufacturer TeslaMotors The company's plan to build a Gigafactory super lithium battery factory may be very good.

In recent years, under the guidance and promotion of the national policy, the new energy automobile industry in China has developed rapidly With the new energy automobile entering the scrap period gradually, the recycling of vehicle power batteries will become more and more prominent.

Tip: According to foreign media reports, Ruben-Simon KU hnel and David Reber, two researchers from the Department of Energy Conversion Materials of the Swiss National Federal Laboratory, have developed a new scheme, in which sodium bis (fluorosulfonyl) imide is used The salt is soluble in water, and 7 grams of sodium FSI and 1 gram of water can be mixed into a transparent solution.

The ternary polymer lithium battery refers to a lithium battery using a nickel-cobalt-manganate (Li(NiCoMn)O2) ternary positive electrode material for the positive electrode material, and a ternary composite positive electrode material precursor product, which is a nickel salt, a cobalt salt, a manganese salt As raw materials, the ratio of nickel-cobalt-manganese can be adjusted according to actual needs.

The growth of the current MP3 market continuously increases MP3 consumption group is becoming more and more.

On June 14, China's car power battery power industry innovation alliance battery branch was established in Beijing, China auto industry association executive vice President of Dong Yang, Chinese academy of engineering academician Chen, miit Siming Liu, vice President of CATL Berenikeullmann leaders and experts, as well as dozens of companies such as colleague to attend the meeting, the CATL assistant chairman Dr Meng Xiangfeng founding conference Dong Yang, Chen, Siming Liu and Berenikeullmann for power battery branch was unveiled.

The energy density is the biggest bottleneck of development to restrict the current lithium ion batteries Whether mobile phones or electric cars, people are looking forward that the battery energy density can reach a new level, which makes the battery life of the product or product range will no longer be the main troubling factors.

The essence of rapid charge and discharge of lithium batteries is that lithium ions can be quickly deintercalated between positive and negative materials Battery material properties, process design, and charge and discharge systems all have an impact on high current charging performance.

New method of mobile phone battery longevity Battery maintenance: In order to ensure the safety of the secondary battery during charging and discharging and to meet the performance requirements of its design, the following precautions and tips are summarized: 1) Suitable use and storage environment Whether it is nickel or lithium, it imposes strict requirements on the temperature and humidity of the environment during use or storage Among all environmental factors, temperature has the greatest influence on the charge and discharge performance of the battery.

Lithium battery charging cycle has a close relationship with lithium battery life A charging cycle refers to a complete charging and discharging process of a lithium battery.
