How to design the internal structure of a safe lithium battery pack

How to design the internal structure of a safe lithium battery pack? All lithium battery pack failures are caused by short-circuit faults. The conditions that lead to short-circuit faults experience overcharge, overdischarge, overcurrent, overtemperature, etc., all based on the internal structure of the lithium battery. of. The positive and negative levels of the lithium battery pack should be kept clean. The electrolyte and diaphragm of the lithium battery should be crystallized when traveling, but during the production process, the electrolyte and diaphragm of the lithium battery cannot be protected from metal dust, copper or aluminum. Platinum and other debris. Lithium battery will overheat when it is not in moderate application (overcharging, power loss, overcurrent) or in extreme natural environment (excessive temperature), and the slag will get rid of the silence of normal temperature state, and then make it in hotter The thermal movement of the indoor space of the lithium battery electrolyte. Next, if the debris is close to the diaphragm, the hot debris will endanger the isolation purpose of the diaphragm and cause a short circuit failure. Therefore, now we have a high polymer lithium battery, replacing the liquid electrolyte solution with a colloidal solution electrolyte solution, which can reduce the probability of short-circuit failure. Lithium battery pack principle: Lithium battery pack is a kind of secondary battery (rechargeable battery). The key to its work is to store and release kinetic energy through the interweaving and deintercalation of lithium batteries in the middle of positive and negative. In the whole process of battery charging, the lithium battery will be caused at the positive stage of the rechargeable battery, and the resulting lithium battery will enter the negative stage according to the lithium battery electrolyte. Carbon as a negative-level lamellar structure, with many microporous plates, so that the negative-level lithium battery is placed in the carbon microporous plate. The more lithium batteries are placed, the greater the battery charging capacity. . Similarly, when the rechargeable battery is charged and discharged, the lithium battery placed in the carbon layer of the negative stage is also taken off and moved back to the positive stage again. The more returnable lithium batteries, the larger the volume; the basic principle of the composition of lithium battery packs. 1. Positive structure. Shape memory alloy 4 (lithium iron phosphate) + conductive agent (acetylene black) + adhesive (PVDF) + liquid collector (aluminum platinum). 2. Negative structure. High-purity graphite + conductive agent (acetylene black) + adhesive (PVDF) + negative current collector (copper pond). The lithium iron phosphate battery pack is structurally stable during the charging and discharging process of lithium.
