Embodiment 1
[0039] In this embodiment, the injectable / pumpable lithium battery is an injectable lithium slurry battery, and the maintenance regeneration is an offline maintenance and regeneration mode.
[0040] figure 1 This is a schematic diagram of the full life cycle operation mode of the liquid-injected lithium slurry battery in this embodiment. When the liquid-injection lithium slurry battery leaves the factory, the positive electrode sheet of the liquid-injection lithium slurry battery contains dry positive electrode active conductive particles, wherein the positive electrode active conductive particles are composites or mixtures of positive electrode active materials and conductive components; liquid injection The negative electrode sheet of the lithium slurry battery contains dry negative electrode active conductive particles, wherein the negative electrode active conductive particles are composites or mixtures of negative electrode active materials and conductive components. The...
Embodiment 2
[0046] In this embodiment, the injectable / pumpable lithium battery is a grouting type lithium slurry battery, and the maintenance regeneration is an online maintenance regeneration mode.
[0047] figure 2 A schematic diagram of the full life cycle operation mode of the grouting type lithium slurry battery in this embodiment. When the grouting type lithium slurry battery leaves the factory, the positive electrode composite powder material and the negative electrode composite powder material of the grouting type lithium slurry battery are respectively mixed with the non-reactive active electrolyte to form a slurry state, wherein the positive electrode composite powder material is The composite or mixture of the positive electrode active material and the conductive component, the negative electrode composite powder material is the composite or mixture of the negative electrode active material and the conductive component, and the non-reactive active electrolyte is an aqueous or ...
Embodiment 3
[0055] In this embodiment, the refillable / pumpable lithium battery is a bipolar lithium battery. Compared with Embodiment 1 and Embodiment 2, the full life cycle operation mode in this embodiment includes fewer steps.
[0056] image 3 This is a schematic diagram of the full life cycle operation mode of the bipolar lithium battery in this embodiment.
[0057] A bipolar lithium battery includes a plurality of bipolar electrode sheets formed by coating a positive electrode material layer and a negative electrode material layer on both sides of the bipolar plate, which are superimposed on each other, and a plurality of bipolar electrode sheets located at both ends of the several superimposed bipolar electrode sheets. A unipolar electrode sheet coated with a positive electrode material layer or a negative electrode material layer on one side, the bipolar electrode sheet and the unipolar electrode sheet are collectively referred to as electrode sheets, and an isolation layer is pro...
