Technical FAQs 4

Are lead-acid batteries a good choice for energy storage?

Lead–acid batteries have been used for energy storage in utility applications for many years but it has only been in recent years that the demand for battery energy storage has increased.

How much lead does a battery use?

Batteries use 85% of the lead produced worldwide and recycled lead represents 60% of total lead production. Lead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered.

What is the energy density of a lead-acid battery?

The energy density of practical lead-acid batteries is 25-40 Wh/kg, and the manufacturers usually guarantee a “lifetime” of 300-500 charge/discharge cycles. For comparison: the popular nickel-metal hydride rechargeable batteries (widely available in AA and AAA sizes) have the energy density more than twice that of the lead-acid.

Are lead batteries sustainable?

Improvements to lead battery technology have increased cycle life both in deep and shallow cycle applications. Li-ion and other battery types used for energy storage will be discussed to show that lead batteries are technically and economically effective. The sustainability of lead batteries is superior to other battery types.
