With the popularization of new energy vehicles, power batteries are not only the key technology to reduce the overall price of automobiles, but also a major challenge to the environment in the next five years According to the China Automotive Technology and Research Center, in 2020, the scrapped amount of electric vehicle batteries will reach 12-17 million.

In the safety performance test of lithium ion batteries, heavy object impact, extrusion, short circuit, and overcharge test are the top items with the highest failure rate This paper compares and analyzes the relevant test items involved in the IEC62660-2-2010 "secondarylithium-ioncellsforpropulsionofelectricroadvehicles", UL1642-2012 "standardforlithiumbatteries", "safety requirements for lithium-ion power batteries for electric vehicles".

When we choose mobile power, we often see two different types of batteries, lithium ion and lithium polymer, in the product packaging or brochure So what are the differences between them? For some consumers, is lithium polymer battery really better than lithium ion battery? With these questions, today I will give you a detailed introduction to the advantages and disadvantages of these two batteries in terms of price, performance and security.

Consumer electronics and the rapid development of new energy vehicle lithium battery size of the market is growing fast In April 2016, new energy automobile production, sales, respectively 94000 and 90000, was increased by 126.

As for UAV, take Dajiang as example, a piece of unmanned aerial vehicle (UAV) battery with more than 5000 milliampere cost nearly $1000, but power supply that we usually use with 20000 ma cost 100-200 yuan Why is difference so obvious? Take the 20000 ma rechargeable battery into unmanned aerial vehicle (UAV) may be more useful.

A few days ago, a market research company Reportlinker announced in the report that the battery energy storage systems market is expected to be grown from $198 billion in 2018 to $2023 in 8.

In 2018, the electric car is all a bit of a "fire" According to incomplete statistics, in the first half of 2018, the electric car 10 burning accident happened.

In many electrochemical energy storage systems, lithium ion (Li) (secondary) batteries for its high energy density and long cycle life and other advantages, has gained scale application However, due to the wide application of lithium resources in industry, using alternative electrochemical energy storage amount is limited, have report estimates that by 2050 there will be up to a quarter of global lithium resources are used for electric cars.

The water battery, a kind of water is used as raw materials and produce electric battery, the battery besides itself contain solid material, as long as the water which can generate electricity Since the 1990 s, as people can be used in the water, high-energy, long-life energy demand increase, aluminum - water battery research carried out formally.

Recently, the 2012 new energy automobile industry technological innovation project support, new energy vehicle and 25The battery shortlisted for the project The move for the burgeoning domestic new energy industry competition selects the "national army".
