VW & Quantumscape Bring Solid State Batteries Closer To Reality
A couple weeks ago, Volkswagen and Quantumscape claimed to have solved a key problem in the development of solid state batteries. Solid state batteries would give great benefits to both the automotive world and other industries, but have so far been frustrated by the inability to come up with a separator that can keep the battery from failing prematurely. Quantumscape claims that it has come up with a better separator that has been proven to work.
For those unfamiliar, batteries have cathodes and anodes, the positive and negative electrodes. These must be separated to prevent the battery from short circuiting. At worst, separation failures can cause fires and explosions, while at best, they prevent the battery from holding a charge. This separator must also be permeable to lithium or other ions that have to pass from one side of the battery or the other during charge an discharge.
