In recent years, benefiting from the rapid update of electric vehicle technology and the promotion of policies, China's new energy automobile industry has shown a “blowout” growth As a battery component of electric vehicles, the technical level directly affects or even restricts the development of new energy automobile industry.

A few days ago, a good young man called us and said that when he used the Agilent 34401A6 half-digit meter to measure the voltage of the lithium power battery, there was a bizarre measurement phenomenon: at the beginning of the test, the lithium power battery voltage was 423621V.

Due to the fact that the company has not yet achieved profitability in the 15 years since its founding, Tesla, the senior electric vehicle manufacturer in the United States, has received much attention Recently, some analysts said that Tesla now consumes $6,500 per minute.

It is reported that the world's largest lithium-ion battery system built by Tesla, that is, the Hornsdale energy storage system, has been officially launched on December 1st The local government officials said the Hornsdale energy storage system.

Graphene has a large specific surface area, good electrical conductivity and thermal conductivity, and is a potential energy storage material Graphene as an energy storage material has the following advantages: Graphite raw materials are abundant and cheap, and the cost of graphene prepared by chemical method is low; the low-temperature expansion method invented by our research group has greatly reduced the cost.

Zheng Yonggang, chairman of Shanshan Holdings Board of Directors, has multiple labels He is the first clothing brand in China in the 1990s, and a new energy leader with a forward-looking and successful transformation of lithium battery materials.

Recently, the Ministry of Industry and Information Technology announced the 310th batch of "Road Motor Vehicle Manufacturing Enterprises and Products Announcement" new products Among them, Luzhouzhou and Xinri's two new energy vehicles are quite interesting because their power batteries are powered by Yuyou Power produces and supplies the world's first lithium-rich manganese-based soft pack battery.

The correct use of the lithium power battery for electric vehicles is as follows: 1, the battery does not need to "activate" Lithium batteries do not need to be charged for more than 12 hours in the first three times, and lithium batteries have no memory 2, battery charging Use the charger specified by the manufacturer to charge.

China's power battery company Ningde era is attacking the city on the international market Recently, at the Beijing Auto Show, Nissan announced that it will introduce 20 electric models to the Chinese market in the next five years.

Many people know very little about lithium power batteries, and they don't know the difference between fuel cells and lithium power batteries How do you decide during the selection process? Let's analyze the two power supplies for everyone.
