What is the internal structure of a safe lithium-ion battery pack? All lithium-ion battery packs are caused by short-circuit failures, resulting in overtilization, overlapping, overcurrent, super temperature, etc., all according to lithium-ion batteries Internal structure caused. The positive and negative levels of the lithium-ion battery should be kept clean, and the lithium-ion battery electrolyte, the diaphragm should be crystallized during production, but the lithium ion battery electrolyte and the diaphragm cannot be guarded in the dust, copper Mooring or aluminum platinum, etc.
Lithium is not in moderate application (overcharge, loss, overcurrent) or at an extremely natural environment (too high temperature), will be over temperature, the silence of the slag is getting rid of in the normal temperature state, which in turn is in hot Lithium-ion battery electrolyte indoor space surrounding heat. Connected, if the residue is close to the diaphragm, the heat eligible will harm the diaphragm isolation, which will also cause short circuit failure. Therefore, there is now a high polymer lithium electrolyte, replacing the liquid electrolyte solution with a colloidal solution, can reduce the probability of short-circuit failure.
Lithium-ion battery pack principle: lithium electric package is a secondary battery (rechargeable battery), and the key to the intensity of lithium-ion batteries in the center of work, complete storage and release of kinetic energy. In the full process of battery charging, the lithium ion battery will cause the positive level of the rechargeable battery, and the lithium ion battery caused by the lithium ion battery electrolyte into the negative level. Carbon is a negatively grade-based structure, with a lot of microplate, which is a negative lithium ion battery in the microve plate of carbon, the more lithium ion batteries, the battery charging capacity Greater.
Similarly, when the rechargeable battery is charged and discharge, the lithium ion battery in the negative carbon layer is also taken off, and move back to the positive level again. The more lithium-ion batteries are returned, the greater the volume; the basic principle of the composition of the lithium ion battery pack. 1, the positive construction.
Shape memory alloy 4 (lithium iron phosphate) + conductive agent (acetylene black) + adhesive (PVDF) + set liquid (aluminum platinum). 2, negative construction. High-purity graphite + conductive agent (acetylene black) + adhesive (PVDF) + collective negative (copper).
Lithium iron phosphate ion battery pack is structurally stable during lithium-charged discharge. .
