Past, present, and future of lead–acid batteries

W hen Gaston Planté invented the lead–acid battery more than 160 years ago, he could not have fore-seen it spurring a multibillion-dol- lar industry. 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

CADMIUM

This proposal has now been sent to the European Parliament, which has reintroduced the concept of a NiCd battery ban as well as a ban on small sealed lead acid batteries. Until the outcome of the EU''s proposed Battery Directive has been resolved, there will continue to be uncertainty and weakness in cadmium prices.
