Lead-acid batteries. These have been used in several electricity-storage applications for more than 30 years. This technology offers low energy density (the amount of electricity that can be stored in a given size and weight of battery) and limited lifetime (700 to 1000 cycles) compared with more advanced technologies.
These three types of TES cover a wide range of operating temperatures (i.e., between −40 C and 700 C for common applications) and a wide interval of energy storage capacity (i.e., 10 - 2250 MJ / m 3, Fig. 2), making TES an interesting technology for many short-term and long-term storage applications, from small size domestic hot water …
