One of the few businesses working to create what is known as a lithium metal battery is QuantumScape.
The anode, which is often formed of graphite, silicon, or a combination of these materials, and the cathode, which is typically comprised of lithium mixed with other metals, are separated
The limiting elements in batteries are often things like the thickness of the separator and the energy capacity of the anode.
But if you can do away with the anode, you may greatly increase the battery's energy density and speed up the charging process.
It is a battery architecture that has been utilised in single-use batteries and has been the subject of decades of research in battery labs.
However, problems with rechargeable lithium metal batteries have repeatedly arisen.
