2. History: The lead–acid battery was invented in 1859 by French physicist Gaston Planté It is the oldest type of rechargeable battery (by passing a reverse current through it). As they are inexpensive compared to newer technologies, lead–acid batteries are widely used even when surge current is not important and other designs could provide higher energy
The pollution control problem of discarded lead-acid batteries has become increasingly prominent in China. An extended producer responsibility system must be implemented to solve the problem of
lead from end-of-life lead-acid batteries, due to increasing energy costs of pyrometallurgical lead recovery, the resulting CO2 emissions and the catastrophic health implications of lead exposure from lead-to-air emissions.

One possibility would be discarded lead-acid car batteries. Today, old car batteries are recycled, with most of the lead used to produce new batteries. But battery technology is changing rapidly, and the future will likely bring new, more efficient options. At that point, the 250 million lead-acid batteries in US cars today will become waste—and that could cause environmental problems.
The use of batteries, specifically secondary batteries like lithium-ion (LiBs), lead-acid (LABs), nickel-metal hydride batteries (NiMH), and nickel-cadmium (Ni–Cd), has witnessed a remarkable surge [1, 2].
