Method for manufacturing secondary metal lighium cell cathode

The method includes steps: (1) plastering lithium foils onto two sides of metal mesh as framework; with PTFE films filled up at both sides, dual roller press rolls the lithium foils on metal mesh, or coating conducting resin to two sides of metal mesh, plastering lithium foils, and rolling the lithium foils on metal mesh by dual roller press in order to agglutinate them firmly; (2) immerging lithium foils and metal mesh into treating liquid including components: copolymer between PVDF and perfluoro propylene, silica in gas phase, alumina powder and tetrahydrofuran for treatment; (3) die cutting pole ears. The metal mesh restricts growth of lithium crystal effectively so as to solve phenomena of piercing diaphragms by lithium crystal branches. The invention raises lifetime of duty cycle operation of battery greatly.
