With the development of lithium batteries, more and more people feel that making lead-acid batteries no longer pays off. This is not the case; lead-acid batteries remain a major trend for the coming decades. The reasons are as follows:

1. Lithium battery technology still needs improvement, with low safety

A lithium battery is indeed a good direction to develop, but many aspects still need constructive breakthroughs, such as safety and pass rate.

Everyone knows the 2016 Samsung Note 7 battery explosion. The lithium battery in a phone is relatively simple, with no series-parallel connections and energy of only about 2 Wh, yet its explosion rate still reached one in a million; the lithium batteries used in electric vehicles have larger energy and complex series structures, so their safety is correspondingly lower.

2. Lead-acid batteries have low production cost and low environmental pollution

Compared with lithium batteries, the production cost of lead-acid batteries is only about one-third, and the raw materials can be recycled, so environmental pollution is relatively less.

3. Lead-acid batteries have a mature production process and simple equipment

Lead-acid batteries have been developed for more than 150 years, with simple equipment and a mature production process. In recent years, graphene and gel batteries have gradually emerged, showing their lasting vitality.

From the three points above, it is not hard to see that lead-acid batteries will surely have decades of life ahead, and lithium batteries still need innovative technology.
