A laminated core for a laminated lithium-ion battery capable of reducing internal temperature rise |
| abstract |
The invention provides a laminated core for a laminated lithium ion battery capable of reducing the internal temperature rise. The present invention provides two or more positive electrode sheets and a stacked core for lithium ion batteries including these positive electrode sheets. Due to the different impedances of different positive electrode sheets, the positive electrode sheets with relatively small impedance are stacked on the stack for lithium ion batteries. In the inner layer of the core, the positive electrode sheet with relatively large impedance is stacked on the outer layer of the stacked core for lithium ion batteries. Under high-rate charging, the heat generation in the high-temperature hot zone that is not easy to dissipate heat inside the battery is reduced, thereby reducing the temperature rise of the battery under high-rate charging. In addition, when the impedance of the positive electrode sheet in the inner layer of the stacked core is reduced by increasing the content of the conductive agent, the outer layer area can still be coated with a higher content of active material, achieving the technical effect of reducing the temperature rise of the battery and reducing the loss of energy density. . |
