Ternary polymer lithium-ion batteries refer to lithium-ion batteries that use nickel cobalt manganese oxide (Li (NiCoMn) O2) as the cathode material. The precursor product of ternary composite cathode material is made of nickel salt, cobalt salt, and manganese salt as raw materials, and the pr...

A 'big gamble' after 'falling behind' Fully equipped with blade batteries is a big gamble for BYD. Recently, according to the financial report released by BYD, in 2020, BYD sold a total of 427000 vehicles, with new energy vehicle production...

Driving the rise of lithium iron phosphate batteries Previously, pure electric passenger cars tended to choose ternary lithium-ion batteries with higher energy density, while iron phosphate lithium-ion batteries were more commonly used in commercial vehicles. However, ternar...

In 2020, there were 124 incidents of spontaneous combustion and smoke from electric vehicles. "In Wang Chuanfu's view, if not fundamentally corrected and allowed safety accidents to escalate, the problem of battery detonation will become the" number one enemy "for the better...

On April 7th, BYD simultaneously announced four new cars at the Chongqing New Product Announcement Conference, namely the 2021 Tang EV, Qin PLUSEV, Song PLUSEV, and 2021 e2. After comprehensive subsidies, the selling price ranges from 99800 to 314800 yuan. It is worth noting that all the new c...

Car starting batteries, also known as car batteries, are commonly known as car batteries. Traditional automotive starting batteries are divided into lead-acid batteries and maintenance-free batteries (a type of lead-acid battery). Power lithium battery plates are mostly made of lead calcium al...

In terms of battery maintenance, Wang Zidong stated that power lithium batteries need to be maintained, but currently many companies do not reserve maintenance interfaces for their battery packs, making this effective repair method difficult to popularize. We need to improve from two aspects:...

The Development Trend of Industrialization of New Energy Vehicles At present, most electric vehicle products are transformed from traditional cars. Prince Dong believes that in the design of electric vehicles, the thinking of car companies has been confined by traditional ca...

2. Safety issues with power lithium batteries. Factors such as power lithium battery materials, separators, adhesives, structures, sealing, production processes, and production process control may all cause fire accidents. Although it is difficult to determine the specific cause of a power lit...

Comparing the layout of domestic and overseas companies, it can be found that the cooperative car companies of domestic battery companies are mostly domestic brands, with market planning concentrated in China and relatively closed overall. International mainstream automotive companies' bat...
