At present, lead-acid batteries still occupy about 75% of the market share in the secondary power supply, which shows that lead-acid batteries have a strong vitality and market advantages.
What are the advantages of lead-acid batteries?
Firstly, the recycling rate of lead-acid battery resources is particularly high, and the regeneration rate of lead can be as high as 98%, which is incomparable to other products. In other words, the production and use of lead-acid batteries hardly consume the lead resources on the earth, and when other resources on the earth are basically exhausted after decades or centuries, lead-acid batteries can still serve mankind very well.
Secondly, lead-acid batteries have a high level of safety, they can be used normally at a high temperature of 100 degrees, and the body will not explode, burn or pollute, which is a great guarantee for personal and facility safety.
Thirdly, the voltage stability of the lead-acid battery is extremely high, which is due to the fact that the lead-acid battery is the only one in the secondary power supply that is made of the same material for both poles, while the electrolyte is also unique. Therefore, the lead-acid battery has a wide temperature range and can be used reliably in the temperature range of -50℃ to +100℃. For example, in the winter in the north, the car can start normally at -40°C or 50°C. In the summer, even if the car engine generates a higher temperature in the south, it will not affect the normal use of the lead-acid battery.
Fourthly, lead-acid batteries are very inexpensive, lasting 3 or 4 years, and with a residual value of around 50%, they are well suited to the needs of a wide range of low-end consumers.
Fifthly, the maintenance and repair of lead-acid batteries are very convenient, and some malfunctioning users can carry out simple maintenance and repair themselves and can guarantee the safety of the situation.
Therefore, the development of human society is, first of all, inseparable from resources; the first is to ensure the safety of consumer goods, the second is the convenience of use, and the third price should be cheap; consumption can be at one’s own pace. Therefore, lead-acid batteries should be the most ideal secondary power source for the above-mentioned human needs.
