Performance comparison between lithium ion batteries and storage batteries

Temperature tolerance: The common operating temperature of lithium ion batteries is - 20-60 degrees Celsius, but generally below 0 degrees Celsius, the performance of lithium ion batteries will decline, and the discharge capacity will decrease accordingly. Therefore, the operating temperature of lithium ion batteries with complete performance is commonly 0 to 40 degrees Celsius. Some special environments require different temperatures for lithium ion batteries, and some can even operate normally in environments of up to 100 degrees Celsius.

The operating temperature of a storage battery is generally required to be between 20 ℃ and 25 ℃. When it is below 15 ℃, its discharge capacity decreases. Every 1 ℃ decrease in temperature decreases its capacity by 1%, while if the temperature is too high (greater than 30 ℃), its life will be greatly shortened.

Cycle life: The cycle times of a lithium ion battery are generally around 2000-3000, while the cycle times of a battery are around 300-500. The cycle life of a lithium ion battery is about five or six times that of a battery.

Mass specific energy (WH/kg): The lithium ion battery is 100-150, and the battery is 30-50.

Volume specific mass (Wh/L): The lithium ion battery is 200-250, and the battery is 60-90.

Charge and discharge: Lithium ion batteries have no memory effect; The battery can be charged and discharged at any time, with low self-discharge and less than 1% monthly self-discharge. The battery can be stored for a long time; Powerful, capable of fast charging and discharging, capable of filling over 80% of the battery in 20 minutes, and discharging the battery in 15 minutes.

The battery has a memory effect and cannot be charged or discharged at any time; There is a serious self discharge phenomenon, and the battery is easy to be scrapped after being stored for a period of time; Low discharge rate, unable to discharge large current for a long time.

There is also a significant difference between lithium ion batteries and batteries in terms of environmental protection. In this era of environmental protection, environmentally friendly and efficient batteries can better conform to the development trend of the times and be widely used. In modern times, lithium ion batteries are used in all aspects of our lives, such as mobile phone batteries, watch batteries, power car batteries, and so on.
