On January 9, the passenger car association released the overall sales situation of the national passenger car market in 2017, and new energy vehicles became the most eye-catching segment -- the monthly sales of December 2017 exceeded 100,000 and the annual sales exceeded 700,000 The rapid expansion of the market behind the domestic new energy battery giants has accelerated the market layout.

"Recently, China's new energy automobile application experience exchange and development conference" held in Shenzhen ping mountain district, the national "863" energy saving and new energy automobile project supervision consulting team Wang Binggang on BBS said, by the end of 2015, cumulative sales of the new energy vehicles in China will be hit more than 30 units, or in our country will become the new energy vehicles accumulative total sales of the most countries in the world Optimistic, electric cars under the high speed development brings hidden trouble also nots allow to ignore.

With the increasing sales share of electric vehicles in the automobile market, the disposal of old batteries in electric vehicles has attracted more and more attention from all walks of life The secondary utilization of used battery components can indirectly reduce the cost and price of batteries and reduce the pollution of battery waste to the ecological environment.

A, An overview of the Polymer lithium battery                                  Polymer lithium battery generally refers to Polymer lithium ion batteries。 According to the electrolyte materials that are used in lithium ion batteries, lithium ion batteries are divided into liquid lithium ion battery (Liquified Lithium – Ion Battery, LIB for short) and polymer lithium ion battery (Polymer Lithium – Ion Battery, for PLB) or plastic lithium ion battery (PlasTIcLithiumIonBatteries, for PLB)Is used in the polymer lithium ion battery cathode materials and liquid lithium ion is the same, the anode materials are divided into cobalt acid lithium, manganese acid lithium, ternary material and lithium iron phosphate material, negative extremely graphite, working principle of the battery is almost the same.

The lithium battery package is safe and has environmental protection, long service life, small volume, light weight and reliable environmental advantages Lithium battery ushers in explosive growth, and expands the size of the market in recent years.

The electrolyte is the ion conduction between battery anode and cathode that effects as conductor, which is made from lithium salt, high purity of organic solvent and additive raw materials matching a certain proportion It play a vital role in the battery energy density, power density, wide application temperature, cycle life and safety performance.

It is reported that Germany is made for Daimler subsidiary EvoBus Akasol lithium ion battery system, and the latter plan launched in IAA commercial motor show in September for new Citaro bus The bus will be equipped with up to 10 AkasolAKASYSTEMOEM battery pack (the maximum capacity of 243 kilowatt-hours).

China Tianqi Lithium is going to buy Chile SQM32 % equity, which is valued $5 billion Chinese ambassador of Chile criticized Chile regulators and tried to stop the deal.

China Energy Storage Press: in recent years, lithium ion battery has been the preferred technology of fixed storage project Due to the advantages of low cost, energy density and the efficiency and safety, lithium ion battery becomes the first choice of many stationary energy storage systems (ESS) technology.

Now, the growth of new energy vehicles go into small explosion stage, but due to various constraints, complete outbreak of the new energy vehicles still need to wait for a period of time Its popularity is growing, especially for pure electric vehicles/new fuel auto industry new energy vehicles which develop closer to its final shape models.
