With the continuous advancement of lithium battery technology, various new types of batteries are emerging one after another, such as ternary lithium-ion batteries, lithium cobalt oxide batteries, and lithium iron phosphate batteries. And now, another brand-new lithium battery has arrived!
In April of this year, a company in California, USA, announced that it had developed a brand-new lithium battery, a radioactive battery that is comparable to graphene batteries.
In mid-May, it was reported that Harvard University had also created a brand-new lithium battery.
It is understood that Harvard University's lithium battery uses a sandwich-like structure and is a lithium metal solid-state battery.
Compared to lithium-ion batteries, solid-state batteries can significantly improve energy density, and are smaller and thinner than liquid lithium batteries.
Furthermore, solid-state batteries offer high flexibility after being made thinner and lighter. Data shows they can withstand hundreds to thousands of bends while maintaining virtually no performance degradation, and are also safer than liquid batteries.
However, the less-than-ideal chemical volatility of lithium metal solid-state batteries makes their development quite challenging. Harvard University has overcome this very hurdle.
It is reported that the lithium metal solid-state battery developed by Harvard is very stable and can achieve more than 100 million charge-discharge cycles under high energy density settings.
This means that if this battery were used in electric vehicles, it should last 10 to 15 years without needing to be replaced. Moreover, it can be fully charged in approximately ten minutes!
