Hengdian Dongmao(002056) announced on the evening of December 18 that it plans to invest in an annual output of 100 million 18650 high-capacity lithium-ion power batteries The total investment of the project is 425,399,800 yuan, of which 245,399,800 yuan is newly invested in fixed assets and 18.

On April 27, Qian Jiang's motorcycle issued an announcement that the company's board of directors reviewed and passed the "Proposal on Foreign Investment of Holding Companies" three times Agreed to the holding company Zhejiang Qianjiang New Energy Technology Co.

Lithium-air batteries provide more power at the same weight and are therefore widely used in electric vehicles and other mobile electronic devices However, lithium-air batteries have many disadvantages: high heat(a large amount of chemical energy is converted into heat energy and not provided to equipment), short life, expensive and complex manufacturing processes(charging air into the battery requires expensive equipment, And very troublesome).

The energy density of lithium iron phosphate batteries is far less than that of lithium ternary batteries, but its safety is generally considered to be better than lithium ternary batteries First, energy density.

When lithium batteries are used up to the standard of disuse or when they suddenly fail, they are often disassembled to analyze what is causing the battery's performance to decay or plummet During the disassembly analysis of lithium batteries, it was found that the battery with poor circulation performance was often related to the poor infiltration effect of electrolytes on the electrode.

The oxidation and decomposition of ordinary lithium ion cell electrolyte under high voltage limits the development of high voltage lithium ion battery In order to solve this problem, it is necessary to design and synthesize new high voltage resistant electrolyte or find suitable electrolyte additives.

Batteries are used, feel not durable, capacity is not more than before, these are the continuous decay of the cycle life Next, we will talk about the long-term reliable use of lithium-ion batteries: cyclic life.

1, in a low-power system, replace the previous secondary battery with a lithium ion capacitorNotes:Lithium-ion capacitors have large capacity and low discharge currents.

Recently, Anyang City issued the "Implementation Opinions on Further Accelerating the Promotion and Application of New Energy Vehicles" Before 2020, a one-time emission reduction award was given to new energy vehicles purchased by non-governmental investment in the city according to the capacity of vehicle-powered batteries.

In 2017, Beijing Dangsheng Materials Technology Co, Ltd.
