Wang Zidong believes that the entire process of manufacturing power lithium-ion batteries in China is not truly automated, but rather every step of the process. For example, to continue the slurry mixing system, many domestic companies operate one tank at a time, rather than continuing. This s...

Power lithium-ion batteries are a crucial factor affecting the development of new energy vehicles. For example, of the 150 electric taxis currently in demonstration operation in Nanchang, only 50 are operating on the road, while the other 100 are unable to function properly due to battery issu...

After the rise of electric vehicles in recent years, there has been a considerable trend. The first batch of electric vehicles have already faced the problem of battery scrapping. However, replacing a new energy vehicle with a battery is even more expensive than replacing a new car, which is t...

The method to deal with collision (mechanical) heat loss is to design the structural safety protection of the battery. For this reason, Professor Ouyang Minggao proposed four design routes: 1. Assembly structure design: plastic frame support+steel strip pre tightening assemb...

To address this issue, the first step is to improve the manufacturing process and reduce impurities in battery manufacturing. This requires selecting a battery manufacturer with good product quality, and then conducting safety predictions for internal short circuits. Before thermal runaway occ...

The experimental data shows that when the temperature of the battery cell reaches 135 ℃, the separator begins to melt and the voltage drops; The battery voltage drops rapidly at 150 ℃; When the temperature reaches 245 ℃, the diaphragm completely collapses, and the battery will experience a...

Due to the rapid development of new energy vehicles, the power lithium-ion battery industry has also received much attention. Power lithium-ion batteries refer to batteries that provide power to electric vehicles, electric trains, electric bicycles, and golf carts. The first...

LG Chemical has certain competitiveness in the field of electric vehicle soft pack batteries, with products featuring high power, high energy density, and high stability. This technology has become the fuse of the dispute between LG Chemical and SKInnovation. LG advocates that SKInnovation pla...

LG Chemical and SKInnovation recently filed a lawsuit on the grounds of leaking trade secrets and patents. Although it appears to be a dispute over technology leakage and talent grabbing, it is essentially a competition for dominant power in the future battery market. Electr...

Recently, the official WeChat account of Ningde Times reported that Ningde Times New Energy Technology Co., Ltd. (hereinafter referred to as "Ningde Times") has signed a power lithium-ion battery cooperation agreement with Volvo Car Group (hereinafter referred to as "Volvo"...
