Energy storage systems: a review

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.
