Nanoporous LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2 as an ultra-fast charge cathode material for aqueous rechargeable lithium batteries

摘要

Nanoporous LiNi_(1/3)Co_(1/3)Mn_(1/3)O_2 (NP-NCM) was synthesized by using vapour grown carbon fibers (VGCFs) as templates. It exhibits excellent electrochemical performance as a cathode material for aqueous rechargeable lithium batteries, especially with ultra-fast charge capability, and 72 mA h g~(-1) can be achieved at a charge time of 20 s.
