Through an environmentally-friendly electrospinning process, KAIST's team created a membrane with nanoscale channels that promote even lithium-ion deposition while maintaining stability against undesirable reactions with the electrolyte. Impressively, this new design enhances the lifespan of lithium-metal anodes to achieve a performance benchmark of 94% capacity retention at a charge rate of one hour over 300 cycles—described by the researchers as ‘world-class performance.’
