Harvard’s solid-state lithium battery might be what we have been looking for as this battery has many benefits. Quick-charging batteries play a vital role in expanding the electric vehicle market, however, modern day lithium batteries take long to charge and are not long-lasting.
Researchers have made efforts to harness the ability of lithium batteries, which have more energy in the same volume.
A lithium-metal battery is considered the holy grail for battery chemistry because of its high capacity and energy density. But the stability of these batteries has always been poor.Xin Li, Associate Professor of Materials Science
Li and other scientists have developed a lithium solid-state battery that lasts long. This battery can charge and discharge at least 10,000 times. The researchers compared this new battery design with a high energy density cathode material.
This battery can increase electric vehicle’s lifespan to that of gasoline cars without needing to replace the battery. It is reported that this battery could come in handy for electric vehicles that can charge within 10 to 20 minutes.
Our research shows that the solid-state battery could be fundamentally different from the commercial liquid electrolyte lithium-ion battery. By studying their fundamental thermodynamics, we can unlock superior performance and harness their abundant opportunities.Li
The main problem with lithium-metal batteries is the chemistry. When Lithium batteries are charging, lithium ions are moved from the cathode to the anode. Dendrites form on the surface of the anode when it is made of lithium metal.
Li and his team developed a multilayer battery that inserts several materials of varying stabilities between the cathode and the anode. This Harvard’s solid-state lithium battery prevents lithium dendrites from penetrating by controlling and containing them.
