What are the differences between lead-acid batteries and lithium battery packs

Environmental protection, lithium batteries are not polluted (not absolutely), while lead-acid batteries are polluted by heavy metal lead; safety, power-type lithium batteries (lithium manganate, lithium iron phosphate) materials are different in safety, lead-acid battery technology It is quite mature and safer than lithium batteries; the specific energy, mass ratio and volume ratio of lithium batteries are about 40% higher than that of lead-acid batteries; in terms of price, the price of lithium batteries with the same capacity is one of the prices of lead-acid batteries. More times. There are many degradation mechanisms of lithium batteries, which can be roughly divided into two types: abuse degradation and normal degradation. Abuse of decay can be guarded against, including overcharge, overdischarge, low temperature, high-power charging and discharging, and so on. Regarding mobile phone usage scenarios: overcharge: electronic devices have circuit protection, and this usually does not happen, so users do not need to worry. Overdischarge: This is a vague concept. Generally speaking, try not to use the mobile phone under 20% of the battery, especially don't use the mobile phone under 5% of the battery, it will cause irreversible damage to the battery. Low temperature: It means that low temperature charging is very harmful. Electronic devices are generally also protected (iPad cannot be charged in low temperatures), so users do not have to worry about it. High-power charge and discharge: The discharge of electronic equipment is generally gentle. Even if you keep playing games, the phone can last for three or four hours. This is 0.2C discharge at most, which is very gentle, and users don’t have to worry about it. Charging is also protected by the circuit of the charger and electronic equipment, so users don’t have to worry about it. Normal decay cannot be guarded. The important influencing factors are the integral of the depth of discharge and the state of charge at rest.
