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...

Their research is all open to the public, and one day when it opens to society, they place this lithium nitride, a small button like battery on the table, with a lead-acid battery next to it. At first glance, a lead-acid battery is heavy, and a button battery is light. I thought this thing was...

Afterwards, John Goodinav synthesized a compound called lithium cobalt oxide. Lithium cobalt oxide is a layered compound that can be used as a lithium source for lithium-ion batteries. Its structure is still stable, which is Goodinav's contribution. After reading Gudinav's article in 1...

However, nowadays, lithium-ion batteries also face many practical challenges, with frequent safety accidents, limited endurance, and energy density improvement approaching the upper limit. Where will lithium-ion batteries go in the future? Who is the ultimate battery of the future in the face...

A few days ago, Ku Shu's article titled "This resource is being seized globally, and a news item has caused turmoil in China's stock market! What does Tesla want to do?" sparked heated discussion. The article mentioned that the arrival of lithium-ion batteries not only laid t...

Nickel hydrogen batteries are a relatively unfamiliar type of battery, and currently there are almost no models equipped with such batteries except for Toyota's models. Nickel hydrogen batteries are also a type of battery with good performance. Nickel hydrogen batteries...

Lithium iron phosphate has no advantage in energy density Although lithium iron phosphate batteries have the aforementioned advantages, they also have some drawbacks, which have led car companies to abandon lithium iron phosphate batteries and switch to ternary lithium ion batteries...
