1. Differences in charging and discharging:
1) 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 easily scrapped after being left unused for a period of time; The discharge rate is small and cannot be discharged with high current for a long time.
2) Lithium batteries have no memory effect and can be charged and discharged at any time. The self discharge of the battery is low, and the monthly self discharge is less than 1%. The battery can be stored for a long time; Powerful, capable of fast charging and discharging, able to fully charge up to 80% in 20 minutes, and fully discharge in 15 minutes.
2. Differences in temperature tolerance:
1) The working temperature of a battery is generally required to be between 20 ℃ and 25 ℃. When it is below 15 ℃, its discharge capacity decreases. For every 1 ℃ decrease in temperature, its capacity decreases by 1%. However, if the temperature is too high (greater than 30 ℃), its lifespan will be greatly shortened.
2) The common working temperature for lithium batteries is -20 to 60 degrees Celsius. However, generally, when the temperature drops below 0 ℃, the performance of lithium batteries will decrease, and the discharge capacity will correspondingly decrease. Therefore, the working temperature for lithium batteries with complete performance is usually 0 to 40 ℃. Some special environments require different temperatures for lithium batteries, and some can even operate normally in environments of hundreds of degrees Celsius.
3. Differences in chemical reaction formulas during discharge:
1) When discharging the battery: negative Pb (s) -2e -+SO42- (aq)=PbSO4 (s).
2) Lithium battery discharge reaction: Li+MnO2=LiMnO2.
