Nanoporous LiNi(1/3)Co(1/3)Mn(1/3)O2 as an ultra-fast charge cathode material for aqueous rechargeable lithium batteries.

Nanoporous LiNi1/3Co1/3Mn1/3O2 (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.
