Analysis of the performance requirements of high-rate battery electrolyte

The selection of high-power batteries has high-active materials and high-temperature characteristics. Lithium-ion battery wholesale 1. In order to obtain high conductivity, a large number of chain esters are selected in the electrolyte. Carboxylates are prone to side reactions at high temperatures and have poor oxidation resistance. 2. In terms of electrolyte additives, in order to reduce the positive resistance of SEI, usually fewer additives are selected, or the film is thinner. Therefore, at high temperatures, the positive and negative electrodes react more strongly with the electrolyte. 3. Positive and negative active substances, generally those with small particles and large BET, have high reactivity and high temperature; 4. There are more conductive agents and relatively few adhesives, so dust is more difficult to control, and the K value is relatively large. So it is easy to do 1. When the high multiplier battery is discharged at high temperature, the performance becomes clearer, and the high multiplier impacts the core FAQ1. High-power batteries may have a major impact on the internal stability of the battery. 1. The best temperature should not exceed 55 degrees 2. The material can increase the multiplier and reduce the temperature rise. The battery can better raise the temperature. 3. A 60C battery is shown in the following figure: The result is that when charged at 2C, discharged at 60C, the highest level of a single cycle is about 200 times, which is actually designed. 4. The performance is not the best, but the most suitable. Generally speaking, the cost-effective performance is good. Lithium-ion battery wholesale If the customer’s normal operating current is 2C, it’s best to design it around 5C, pure personal experience. If the electrolyte of the high multiplier battery can withstand high temperatures, add additives with high temperature resistance. In this additive, the viscosity of the original electrolyte increases, the movement of ions decreases, and the polarization wave increases. With the decline of the performance of the multiplier, to overcome the temporary incompatibility between high temperature and high multiplier, further research!
