KAIST announces battery separator with 94% capacity retention after 100 fast-charge cycles
KAIST announced that a research team developed a battery separator that controls lithium-ion pathways by adjusting the molecular alignment of liquid-crystal polymers. The team said a lithium-metal battery using the separator retained 94% of its initial capacity after 100 charge-discharge cycles under fast-charging conditions theoretically allowing a charge in about 15 minutes.
