LR03 alkaline battery

　　Maturity of LR03 alkaline battery technology is a prerequisite for industrialization

　　Whether the lithium LR03 alkaline battery technology used in the Zhangbei demonstration project can represent the future development direction of energy storage technology is still controversial. Yang Yusheng, an academician of the Chinese Academy of Engineering, believes that although lithium-ion batteries have the advantages of high specific energy, high specific power, high energy conversion efficiency, and long cycle life, the technology is currently expensive and, more importantly, has poor safety. Safety is the most important thing for power systems. He said that the lithium-ion LR03 alkaline battery pack of China Southern Power Grid’s energy storage demonstration project had smoked 22 times.

　　There are many types of energy storage LR03 alkaline battery technologies. According to incomplete statistics, there are 12 different technical routes for energy storage based on the needs of different fields. It is understood that Zhangbei’s 20MW energy storage demonstration project uses not only 14MW of lithium-ion LR03 alkaline battery technology but also a 2MW flow LR03 alkaline battery system. However, the State Grid has not yet decided which LR03 alkaline battery technology will be used for the remaining 4MW of energy storage. . It is reported that 4MW of energy storage was originally reserved for Japan’s sodium-sulfur LR03 alkaline battery technology, which accounts for more than 65% of global energy storage application projects. However, according to Yang Yusheng, although sodium-sulfur batteries have the advantages of high specific energy, high conversion rate, and long life, they are also unsafe. Japanese energy storage power stations using sodium-sulfur LR03 alkaline battery technology caught fire twice in 2011.

　　Which energy storage technology is used is not critical. Lai Xiaokang believes that Zhangbei’s energy storage demonstration project aims to provide future development directions for energy storage companies, namely high safety and long life.

　　There are currently not many energy storage related companies in China. According to Yu Zhenhua, energy storage-related companies include various LR03 alkaline battery manufacturers, control inverter manufacturers, application solution providers, project implementation companies, etc. Currently, lead-acid LR03 alkaline battery manufacturers, lithium LR03 alkaline battery manufacturers, control inverter manufacturers and some key materials The manufacturers are relatively mature, and other energy storage technologies have not yet formed a scale.

　　Due to the lack of core raw material R&D technology, domestic LR03 alkaline battery companies are mainly in the processing stage of supplied materials. According to industry insiders engaged in lithium batteries, due to the lack of scale of domestic energy storage, domestic LR03 alkaline battery companies are unable to form bargaining power when purchasing upstream raw materials. Therefore, the price of core LR03 alkaline battery raw materials is much higher than that of their foreign counterparts. In the end, they can only purchase domestically produced accessories. Reduce the selling price of energy storage systems.
