As a Lithium Battery For Ebike Factory, share it with you. All lithium
battery pack faults are caused by short-circuit faults. The conditions that lead
to short-circuit faults experience overcharge, overdischarge, overcurrent,
overtemperature, etc., all caused by the internal structure of the lithium
battery. 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. However, during the processing, the electrolyte and
diaphragm of the lithium battery cannot avoid being stained with metal material
dust, copper or aluminum Platinum and other debris.

Lithium battery will over-temperature 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 quiet condition of normal temperature, and then make it in hotter Thermal movement of the indoor space of the lithium battery electrolyte. Next, if the debris is close to the diaphragm, the hot debris will harm the isolation of the diaphragm and cause a short circuit failure. Therefore, now we have a high-polymer lithium battery, using a colloidal solution electrolyte solution instead of a liquid electrolyte solution, which can reduce the probability of short-circuit failure.
Principle of lithium battery pack: 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 crossover and deintercalation of lithium-ion batteries between positive and negative.
In the whole process of battery charging, the lithium ion battery will be caused at the positive stage of the rechargeable battery, and the resulting lithium ion battery will enter the negative stage according to the lithium battery electrolyte. Carbon as a negative stage has a laminar structure with many microporous plates, so that negative lithium-ion batteries are placed in the carbon microporous plates. The more lithium-ion batteries are inserted, the battery charging capacity will be improved. Bigger. Similarly, when the rechargeable battery is charged and discharged, the lithium-ion battery placed in the negative stage carbon layer is also taken off and moved back to the positive stage again. The more positive lithium-ion batteries, the larger their volume;
The basic principle of the composition of lithium battery pack.
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.
