▎ 摘　　要

NOVELTY - Lithium-air battery anode nano composite material (I), is new. The composite material comprises layered composite metal hydroxide (II), and reduced graphene oxide (III). USE - The material is useful for lithium-air battery. ADVANTAGE - The material: solve the problems of low capacity, poor cycling and low multiplication of traditional anode materials; is simple to prepare and economical; and used in large-scale lithium battery production process. DETAILED DESCRIPTION - Lithium-air battery anode nano composite material of formula (M1(2+)1-xM1(3+)x(OH)2)(x+)A1(n-)x divide by n.mH2O.yrGO (I), is new. The composite material comprises layered composite metal hydroxide of formula (M1(2+)1-xM1(3+)x(OH)2)(x+)A1(n-)x divide by n.mH2O (II), and reduced graphene oxide of formula (rGO) (III). The layered composite metal hydroxide is an anionic layered compound. M1(2+) and M1(3+) = bivalent and trivalent metal cations; A1(n-) = an interlayer anion; n = valence number of the anion; X = molar ratio of M1(3+) to (M1(2+) + M1(3+); m = number of interlayer water molecules; and y = molar ratio of reduced graphene oxide to the layered composite metal hydroxide . An INDEPENDENT CLAIM is also included for preparing the lithium-air battery anode nano composite material.
