Simple analysis of several lithium batteries

1. High-rate lithium battery If the lithium battery uses a high-rate battery cell, the battery is mostly used in electrical equipment that requires high current discharge, such as rc high-speed racing, formula racing, heavy-duty plant protection drones, and so on. 2. Low-temperature lithium battery. If the lithium battery uses a low-temperature battery cell, it is basically used in winter or in a relatively cold working environment. Because the operation in a low-temperature environment is more complicated, the battery performance requirements will be relatively high, and the price is relatively low. It will be more expensive. Low-temperature lithium battery performance characteristics: (1) High low-temperature discharge performance, discharge at 0.2c at -40°C, with an efficiency of more than 75%; at -30°C, discharge at 0.2c, with a discharge capacity of 85%; (2) Work Wide temperature range, -50C to 50C; (3) Excellent low-temperature cycle performance, charge and discharge at 0.5c at -30℃, keep the capacity above 85% after 300 cycles; (4) High safety performance, pass UL/ CE/UN and other battery certification; (5) The size is flexible and can be customized according to the size and shape of the customer; (6) It has the capability of batch processing and the battery consistency is good; 3. The general lithium battery is generally used. For battery cells, the electronic equipment should not have very high power requirements. It is basically used in a normal environment, and the discharge current continues to be stable and small, but the cycle life of the battery should be more important. There are many domestic manufacturers of general 　-type lithium batteries, and the cycle life times range from 300 to 500 times. The lithium battery manufacturers with relatively strong processing and manufacturing technology have a relatively strong comprehensive strength in processing and manufacturing technology. If the lithium battery is operated in accordance with the manufacturer's specifications, the service life is basically more than 500 times.
