In 1859, the Frenchman Plante invented the lead-acid battery.

Why do lead-acid batteries still stand firm in the market after more than a hundred years? Why is the lead-acid battery installation rate of electric bicycles still exceeding 80% to this day?

When we know the advantages of lead-acid batteries, we believe that the answers to the above questions are readily available.

High resource recycling rate

The manufacturing process of lead-acid batteries is relatively simple, with the main raw materials being PbO, Pb, H2SO4, etc.

The manufacturing process includes steps such as melting, casting, slicing, and assembly.

The core material among them is lead, and the regeneration rate of lead can reach up to 98%, which is incomparable to other products. That is to say, the production and use of lead-acid batteries almost do not consume lead resources on Earth.

Lead ore

After decades or hundreds of years, when all other resources on Earth are basically consumed, lead-acid batteries can still serve humanity well.

High security

According to public sources, lead-acid batteries can still be used normally at a high temperature of 100 degrees Celsius, and the body will not experience problems such as explosion, combustion, or pollution.

Compared to lithium and sodium batteries, vehicles equipped with lead-acid batteries are more guaranteed for personal safety and the safety of parking facilities.

High voltage stability

Lead acid batteries are the only type of secondary power source where the two poles are made of the same material, and the electrolyte also has uniqueness. Therefore, they have a wide temperature range and can be reliably used within the temperature range of -50 ℃+100 ℃.

For example, in winter in the north, cars can start normally at temperatures below -40 ℃ and 50 ℃. In summer, even higher engine temperatures in the south will not affect the normal use of lead-acid batteries.

Cheap price

The price of lead-acid batteries is low, and entry-level lead-acid batteries with a capacity of 48V 20Ah can be exchanged for new ones for just over 200 yuan.

With careful maintenance, it can be used for 3-4 years.

Even if the battery is scrapped and recycled in the future, it can still generate about 50% of residual value. Calculated, it only costs about 10 cents per day, which is very suitable for the vast low-end consumer group.

Easy maintenance

The disassembly of lead-acid batteries is very simple, and many friends extend the battery's lifespan by adding distilled water and electrolyte themselves.

summary

In summary, lead-acid batteries have advantages such as high resource recycling efficiency, high safety, high voltage stability, low price, and convenient maintenance.

This is also why even after so many years, lead-acid batteries still stand firm in the battery market.
