Abstract
The invention relates to a preparation method of a negative electrode material of a battery, and particularly relates to a preparation method of a sodium-nickel battery shell insulation material. The method comprises the steps of firstly polishing a pasting surface of a battery, coating gluewater on a piece of mica paper, then winding a gumming mica tape on a battery shell with the winding direction being transverse, heating to 150 DEG C after winding and drying winding, and solidifying 5-8 h. The preparation method provided by the invention has the advantages of being unique, and enabling a battery insulating layer to be high temperature resistant and weather resistant, so as to improve the current security of the battery and prolong the service life of the battery.
Description
