▎ 摘　　要

NOVELTY - The shell comprises shell. The outer side and inner side of shell are provided with coating, where the coating comprises gas gel carbon nano-tube or graphene, porous material and fiber tissue. The coating comprises 10% to 25% of gas gel, 10% to 30% of carbon nanotube or graphene, 20% to 30% of porous material and 20% to 30% of fibrous tissue in terms of weight percentage. The gas gel comprises graphite oxide, silica gas gel, and alumina gas gel. The shell is an aluminum shell or a steel shell. USE - Used as battery shell. ADVANTAGE - The shell: realizes heat preservation performance at low temperature; radiates the battery at high temperature; increases the coefficient of heat conductivity of coating; transmits heat in battery quickly to the outside; adsorbs carbon nano-tube or graphene by porous material at low temperature; occupies whole coating by gas gel; and improves the heat preservation performance of the battery shell in low temperature environment. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a battery; and a battery pack. DESCRIPTION OF DRAWING(S) - The drawing shows a structure explosion schematic diagram of the battery of battery shell.
