Embodiment 1
[0026] like figure 2 As shown, the process for preparing high-load lithium-manganese batteries is as follows:
[0027] 1. Weigh 40kg of electrolytic manganese dioxide powder, bake in a high-temperature oven at 380±5°C for 12 hours, then cool for later use; the purity of the manganese dioxide is 92%;
[0028] 2. Inject 2kg of isopropanol and 15kg of deionized water into the high-speed mixing granulator. After adding the liquid materials, turn on the low speed gear and stir for more than 30s;
[0029] 3. After the stirring is stopped, add 2.7kg of conductive carbon black to the granulator. After adding the conductive agent, first keep stirring at low speed for 30 seconds, then change the stirring speed to high speed and stir for more than 3 minutes;
[0030] 4. After the stirring of the conductive agent is stopped, add the prepared electrolytic manganese dioxide powder into the granulator, the stirring speed is still at high speed, and stir for more than 5 minutes;
[0031] 5...
Embodiment 2
[0033] The process for preparing high-load lithium-manganese batteries is as follows:
[0034] 1. Weigh 60kg of electrolytic manganese dioxide powder, bake it in a high-temperature oven at 380±5°C for 12 hours, and then cool it for later use; the purity of the manganese dioxide is 92%;
[0035] 2. Inject 4kg of isopropanol and 25kg of deionized water into the high-speed mixing granulator. After adding the liquid materials, turn on the low speed gear and stir for more than 30s;
[0036] 3. After the stirring is stopped, add 5kg of conductive carbon black to the granulator. After adding the conductive agent, first maintain the low-speed stirring for 30s, then change the stirring speed to high-speed and stir for more than 3 minutes;
[0037] 4. After the stirring of the conductive agent is stopped, add the prepared electrolytic manganese dioxide powder into the granulator, the stirring speed is still at high speed, and stir for more than 5 minutes;
[0038] 5. After the stirring...
Embodiment 3
[0040] The process for preparing high-load lithium-manganese batteries is as follows:
[0041] 1. Weigh 65kg of electrolytic manganese dioxide powder, bake it in a high-temperature oven at 380±5°C for 12 hours, and then cool it for later use; the purity of the manganese dioxide is 92%;
[0042] 2. Inject 4kg of isopropanol and 20kg of deionized water into the high-speed mixing granulator. After adding the liquid materials, turn on the low speed gear and stir for more than 30s;
[0043] 3. After the stirring is stopped, add 3kg of conductive carbon black to the granulator. After adding the conductive agent, first maintain the low-speed stirring for 30s, then change the stirring speed to high-speed and stir for more than 3 minutes;
[0044] 4. After the stirring of the conductive agent is stopped, add the prepared electrolytic manganese dioxide powder into the granulator, the stirring speed is still at high speed, and stir for more than 5 minutes;
[0045] 5. After the stirring...
