Lead-acid batteries have poor energy storage
Despite an apparently low energy density—30 to 40% of the theoretical limit versus 90% for lithium-ion batteries (LIBs)—lead–acid batteries are made from abundant low-cost materials and nonflammable water-based electrolyte, while manufacturing practices that operate at 99% recycling rates substantially minimize envi-ronmental impact (1).
