Lead-acid (LA) batteries. LA batteries are the most popular and oldest electrochemical energy storage device (invented in 1859). It is made up of two electrodes (a metallic sponge lead anode and a lead dioxide as a cathode, as shown in Fig. 34) immersed in an electrolyte made up of 37% sulphuric acid and 63% water.

The lead sulfuric acid battery was invented 150 years ago, and today, is perhaps one of the best-known electrochemical-energy storage systems. These are primarily used as starter batteries, electric drive batteries, and stationary batteries for emergency electricity supply .
