Do you know what a high-rate battery is?

High-rate batteries generally refer to lithium batteries. Lithium batteries are rechargeable high-rate batteries that rely on lithium ions to move between the positive and negative electrodes to work. During charging and discharging, Li+ is intercalated and deintercalated back and forth between the two electrodes: when recharging the battery, Li+ is deintercalated from the positive electrode and inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Generally, batteries containing lithium elements are used as electrodes. It is a representative of modern high-performance batteries. So what does the lithium battery time rate and rate mean? The time rate is the discharge rate expressed by the discharge time, that is, the time it takes to discharge the rated capacity at a certain current. For example, the 20h rated capacity of Dongfeng brand EQl090E automobile lithium battery is 105Ah, that is, Cu003d105Ah, then the lithium battery should be discharged with a current of 105u0026pide;20u003d5.25A, and it is qualified if it continues to reach 20h. Multiplying rate means that the value of a certain battery's discharge current is a multiple of the rated capacity value. Regarding the above-mentioned EQl090E automotive lithium battery 6-Q-105, if the discharge current is expressed as 0.1CA, it is discharged at a current of 0.1X105u003d10.5A; if the discharge current is expressed as 3CA, it is discharged at a current of 3X105u003d315A. The cut-off voltage refers to the lowest working voltage at which the battery voltage drops to the point where it is no longer suitable for continuous discharge. Generally, the discharge termination voltage under high rate and low temperature conditions is specified lower. Precautions when using high-rate power lithium batteries: 1. Storage requirements: in an environment with a temperature of 25±5°C and a humidity of no more than 50%, the aluminum foil must be guarded against the erosion of air and water vapor during transportation; 2. Carbon The heat dissipation of the layer is worse than that of aluminum foil, so it is necessary to fine-tune the belt speed and baking temperature when coating.
