Abstract

The invention discloses a manufacture method of polymer lithium iron battery cathode and polymer lithium iron battery, which aims to provide a manufacture method of cathode and battery preventing decomposition of passive film at the cathode surface and inhibiting secondary reaction between electrolyte solvent as well as anode and cathode, reducing the generation of gases and preventing battery deformation at high temperature. The cathode manufacture method includes the following steps: mixing the cathode active material and a conductive agent evenly; adding deionized water to prepare cathode slurry material; dissolving Li2CO3 additive in the deionized water to prepare a solution with a percentage concentration by weight of 0.3-1.5%; adding the solution containing Li2CO3 in the cathode slurry material to prepare a mixed slurry material; wholly dissolving a caking agent in a solvent, adding in the mixed slurry material for even stirring, coating on the surface of copper-collected fluid,and then drying, pressing and cutting to prepare the cathode for polymer lithium iron battery.
