The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future - for example in electric vehicles. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. The biggest challenge, hindering its application, is the formation of lithium dendrites, small, needle-like structures, similar to stalagmites in a dripstone cave, over the lithium metal anode. These dendrites often continue to grow until they pierce the separator membrane, causing the battery to short-circuit and ultimately destroying it.
For many years now, experts worldwide have been searching for a solution to this problem. ...
