Analysis of basic parameters of 32650 lithium iron battery

Cell energy density ≥120wh/kg3C charge and discharge 300 times, can maintain capacity above 96%, cell internal resistance ≤8m month self-discharge ≤2%1, 32650 lithium iron phosphate battery cell safety technology-ventilation explosion-proof tube principle: chemistry occurs in the battery Under the reaction conditions, the gas appearing inside will first be concentrated in the vent pipe, which is conducive to the dispersion of the gas inside the battery, and the battery will never explode. 32650 iron-lithium battery cylindrical iron-lithium battery introduces a vent device, which effectively handles the safety problems caused by the high temperature of the battery cell under extreme conditions such as overcharge, short circuit, and collision. When the internal pressure of the 32650 iron-lithium battery cell safety valve reaches 1.8Mpa, the safety valve will open, and the gas will be discharged, guarding against the risk of explosion. 2, 32650 lithium iron phosphate battery cell performance improvement patented technology end welding discarded the lug structure, using the coating and blanking process to make a single-side metal blank cell, and then using the end face welding process. The end-face welding technology can greatly reduce the internal resistance and temperature rise of the battery cell, improve the battery cycle life, and realize the fast charging and discharging of the battery. The group does not need a heat sink. Develop a network-shaped three-dimensional current collector. This structure makes the combination of the coating and the current collector tighter and has stronger adhesion. The micropores on the foil can form a channel for ion movement through the electrolyte, and both sides of the entire pole piece participate in the corresponding positive at the same time. The reaction of the negative electrode. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
