Compare the performance of lithium batteries and batteries

Compare the performance and temperature resistance of lithium batteries and storage batteries: the operating temperature of ordinary lithium batteries is -20-60 ℃, but generally below 0 ℃, the function of the lithium battery will decrease, and the discharge capacity will also decrease, so the lithium battery The full-featured working temperature is generally 0~40℃. Some special environments require different temperatures for lithium batteries, and some can even operate in an environment of several hundred degrees Celsius. The operating temperature of the battery is generally required to be between 20°C and 25°C. Below 15°C, its discharge capacity will drop, the temperature will drop by 1°C, its capacity will drop by 1%, and if the temperature is too high (above 30°C), its life will be greatly shortened. Cycle life: The cycle times of lithium batteries are generally about 2000-3000 times, and the cycle times of batteries are about 300-500 times. The cycle life of lithium batteries is about 5-6 times that of batteries. Mass specific energy (WH/kg): Lithium battery 100-150, battery 30-50. Volume to mass ratio (Wh/L): lithium battery 200-250, battery 60-90. Charge and discharge: Lithium battery has no recall effect; the battery can be charged and discharged at any time, the battery self-discharge is low, the monthly self-discharge is less than 1%, the battery can be stored for a long time; the power is strong, it can be quickly charged and discharged, and it can be charged more than 80% in 20 minutes, 15 It can be discharged in minutes. The battery has a recall effect and cannot be charged and discharged at any time; the self-discharge phenomenon is serious, and the battery is easily obsolete after being left for a period of time; the discharge rate is small, and the discharge point is not long. Lithium batteries are also very different from ordinary batteries in terms of environmental protection. In this era of environmental protection, environmentally friendly and efficient batteries can better adapt to the development trend of the times, and thus be more widely used. In modern times, lithium batteries are used in all aspects of our lives, such as mobile phone batteries, watch batteries, power car batteries, and so on. In these applications, lithium batteries come in various shapes, sizes and types. Among them, the lithium battery pack is a lithium battery with broad development prospects. Lithium battery packs can be used in sub-systems such as small computer rooms and weak motor rooms, communication base stations, indoor and outdoor air-conditioning stations, radio and television, military, petroleum and other unmanned stations. It can be seen from the application range of lithium battery packs that lithium battery packs are highly adaptable to the environment, suitable for unattended places, and save manpower.
