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.
Thermal capacitance is connected to the energy storage capacity and assumes no energy losses. It is defined as the heat flow necessary to change the temperature rate of a medium by one unit in one second: (5.124) C t h = q ( t) d θ ( t) d t = d Q ( t) d t d θ ( t) d t = d Q d θ. The SI unit for thermal capacitance is N-m-K −1 (or J-K −1 ).
