In recent years, science and technology have developed rapidly. Relying on electric power resources to initiate and maintain operations has become an indispensable part of human normal life and development. At present, China's power generation is based on thermal power generation, and its coal consumption ratio is relatively high and its efficiency is low, which is not conducive to energy conservation and emission reduction. The cost of power generation is high. Therefore, the continuous development and optimization of electric energy has become a difficult problem in the field of human power development. The emergence of energy storage technology has become a major aspect of new energy technologies.
Energy storage technology can effectively improve the efficiency of energy use, and can solve the problem of power supply in urban areas. It can also achieve the effect of “cutting peaks and filling valleys” and will greatly improve the stability of the power grid and the quality of power. Lithium-ion battery energy storage systems are emerging all over the world. Lithium-ion battery cathode materials are lithium metal oxides. Lithium-ion battery cathode materials are lithium metal oxides, which are characterized by high efficiency and high energy density, and have a stable discharge voltage. Wide operating temperature range, long storage life, no memory effect and no environmental pollution.
Lithium batteries have high energy storage densities up to 100W•h/kg, 3~5 times that of lead-acid batteries; High output voltages (unit operating voltages above 3.2 V), approximately equal to 3 NiCd or NiMH The series voltage of the rechargeable battery can achieve an energy efficiency of more than 90%. It is adaptable to high and low temperatures and can be used in environments of –20 to 60 °C.
