1. Durability/Battery Life: Lead acid batteries generally have a lifespan of about 2 years, while lithium-ion batteries are more durable, with a lifespan of mostly 4-5 years; And lead-acid batteries generally have a complete charge and discharge cycle of less than 300 times, while lithium-ion...

3. The market-oriented membrane materials are mainly polyolefin membranes made of polyethylene and polypropylene. In the structure of lithium-ion batteries, the separator is one of the key inner components. The performance of the separator determines the interface structure, internal resistanc...

What are the raw materials for lithium iron phosphate batteriesThere are four key factors in the processing of raw materials for lithium iron phosphate battery packs, namely positive electrode materials, negative electrode materials, electrolytes, and separators.Among positive electrode materials, t...

I admire Japanese Kanno very much. He has always insisted on keeping solid electrolytes in place, and I think this is something we can learn from in Japan. Our research on solid-state batteries has basically been released and stopped since the beginning of lithium-ion batteries, but today, we...

4. Who is the ultimate battery of the future? The current lithium-ion batteries are liquid electrolytes, so the energy density has basically reached its limit, around 300 watt hours per kilogram or 350 watt hours per kilogram, which has already reached its limit. So safety i...

Recently, a company in Shenyang has built an electric plane with two seats. But in fact, if you look online, in 2010, a private company in Shanghai had already made an electric plane for two people and successfully tested it. In fact, the Israelis are the ones who do well in electric airplanes...

3. Can "Electric China" Solve the Energy Crisis? Our development of electric vehicles is not for the purpose of developing electric vehicles, but is actually closely related to the energy situation of our country. In 2004, our engineering institute conducted a cons...

At present, NIO Company has a battery change mode. It runs from Beijing to Shenzhen, and there is a place to change the battery every step. It can be changed in a few minutes, and the fastest charging time is about a quarter of an hour, which is the time for a cup of coffee. A quarter of an ho...

From mobile phones and digital products to electric vehicles and ships, lithium-ion batteries have played an increasingly important role in our daily lives. But in recent years, accidents caused by safety issues in lithium-ion batteries have also been impressive. Samsung mobile phone batteries...

Goodenough discovered the commonly used cathode materials lithium cobalt oxide and lithium iron phosphate, but both materials have drawbacks. Lithium cobalt oxide can only extract 0.5 moles of lithium, while lithium iron phosphate is actually an insulator, both of which have drawbacks. We foun...
