Embodiment 1
[0018] This example describes an aqueous solution lithium ion battery with lithium manganate as the positive electrode and copper hydroxide as the negative electrode.
[0019] [1] Positive electrode part: take industrial lithium manganese oxide as positive electrode active material, take conductive carbon black SP as conductive agent, and 60wt% PTFE emulsion as binder, according to active material: conductive agent: binder is 80:10: 10% by weight, stirred and mixed evenly, rolled on a roller press to form a film, dried in an oven at 50°C for 48 hours, and dried in vacuum at 140°C for 19 hours. Pressed on the nickel grid, connected with the copper wire, as the positive electrode. The positive electrode electrolyte is a lithium sulfate aqueous solution with a concentration of 20 wt%.
[0020] [2] Negative electrode part: get copper hydroxide powder, get natural graphite as conductive agent, 60wt% PTFE emulsion is binder, according to active material: conductive agent: binder is...
