The battery has a hydrogen-absorbing alloy for the negative electrode instead of cadmium. Lithium-ion battery: The choice in many consumer electronics and have one of the best energy-to-mass ratios and a very slow self-discharge when not in use. Lithium-ion polymer battery: These batteries are light in weight and can be made in any shape desired.
The hydrogen will be produced nearby through a process called electrolysis. This will be done using excess solar and wind power in spring and fall, when demand for energy is low. Then it can be stored until peak energy demand hits in the summer — at that time, it would be burned at a power plant as a blend of hydrogen and natural gas.. The burning of hydrogen

According to scientists at the International Institute for Applied Systems Analysis (IIASA), abandoned mines could provide a solution. They claim that turning decommissioned mines into vast “gravity batteries” could provide up to 70 terawatts of energy storage. This is enough to match the entire world's daily electricity consumption.
