[0032] Example 1
[0033] Prepare the positive pole piece and negative pole piece according to the following formula:
[0034] Positive electrode slurry formula: active material (T11R): conductive agent 1 (SP): conductive agent 2 (KS-6): pore former (ammonium chloride): binder (PVDF)=92:4:1:1 :2;
[0035] Anode slurry formula: active material (lithium titanate LTO): conductive agent 1 (SP): conductive agent 2 (KS-6): pore former (ammonium chloride): binder (PVDF) = 90:4: 1:1:3.
[0036] Coating the above-mentioned homogeneously mixed substances on the aluminum foil current collector;
[0037] Adjust the oven temperature to 100-150°C, place the above aluminum foil or copper foil current collector on the conveyor belt and bake in the oven;
[0038] After cooling and baking the pole pieces at room temperature, a porous positive electrode piece and a porous negative electrode piece are obtained respectively.
[0039] The positive electrode sheet and the negative electrode sheet without pore...
