Embodiment 1
[0028] The positive electrode active material uses commercial LiMn 2 o 4 . Cathode material according to LiMn 2 o 4 : Acetylene black: PTFE binder = 80:10:10 mass ratio and mix evenly, after drying, roll or roll the mixture onto a stainless steel mesh, and then make an electrode sheet with a thickness of 0.2mm. The negative electrode material is commercialized activated carbon, which is uniformly mixed according to the mass ratio of activated carbon: conductive carbon black: PTFE binder = 80:10:10. After drying, the mixture is rolled or rolled onto a stainless steel mesh, and then made into a 1mm thick electrode pads. Using analytically pure raw materials, configure 1M Li 2 SO 4 Electrolyte, adjust the pH of the electrolyte to 7.50 with LiOH. The positive and negative electrodes are cut according to the specifications, and the hydrophilic treated PP-based separator and the above-mentioned electrolyte are used to pair and assemble into a battery. In the working voltage ...

[0030] The positive electrode active material uses commercial LiMn 2 o 4 . Cathode material according to LiMn 2 o 4 : Acetylene black: PTFE binder = 80:10:10 mass ratio and mix evenly, after drying, roll or roll the mixture onto a stainless steel mesh, and then make an electrode sheet with a thickness of 0.2mm. The negative electrode material is commercialized activated carbon, which is uniformly mixed according to the mass ratio of activated carbon: conductive carbon black: PTFE binder = 80:10:10. After drying, the mixture is rolled or rolled onto a stainless steel mesh, and then made into a 1mm thick electrode pads. Using analytically pure raw materials, configure 1M Li 2 SO 4 Electrolyte, containing 0.4 M lithium acetate solution in the electrolyte, and adjusting the pH value of the electrolyte to 7.50 with LiOH. The positive and negative electrodes are cut according to the specifications, and the hydrophilic treated PP-based separator and the above-mentioned electro...
