The basic manufacturing process of such a Lithium Manganese Dioxide battery for digital cameras is now described by taking a fully sealed cylindrically wound lithium manganese dioxide battery as an example.

1. Preparation of manganese dioxide cathode

The heat-treated electrolytic manganese dioxide powder is mixed with acetylene black, polytetrafluoroethylene emulsion and isopropyl alcohol in a certain ratio and stirred into a paste, and then the paste is uniformly coated on the metal collecting net for heat treatment and crushing. Another method is to form the electrode by heating the prepared positive electrode paste and placing it on both sides of the metal current collector by rolling on a roll machine. The prepared electrode should be placed in an environment where the air humidity is less than 2010.

Second, the preparation of metal lithium anode

According to different battery models, select the lithium strip of the corresponding thickness and width, cut it to the required length, and then cold-weld the lugs on the cut lithium strip. The preparation of the negative electrode must be carried out in an environment where the relative humidity is less than 2%.
