Improving high-energy lithium-ion batteries with carbon filler
Lithium-ion batteries are the significant rechargeable power source for numerous mobile devices in addition to electrical automobiles, but their use is restricted, since they do not provide high power outcome while at the same time permitting reversible power storage. Study reported in Applied Physics Reviews, by AIP Publishing, aims to offer a solution by showing how the incorporation of conductive fillers improves battery performance.
