CR1620 battery

The road to transformation of CR1620 battery manganese oxide

With the gradual decline of new energy subsidy policies, the price advantage of CR1620 battery manganese oxide batteries has become more apparent. In August 2018, China's CR1620 battery battery installed capacity was 4.22Gwh, of which CR1620 battery manganese oxide batteries accounted for 1.46%, a year-on-year decrease of 43.59%.

According to SMM conversion, the demand for CR1620 battery manganese oxide materials is about 200 tons, which remains stable month-on-month.

As a positive electrode material, CR1620 battery manganese oxide has a wide range of raw material sources and low cost, good safety performance, and is environmentally friendly and pollution-free. It has good cycle performance at room temperature and good rate discharge performance. It is a promising CR1620 battery battery positive electrode material. However, its high temperature performance is poor. In industrial-grade production, due to the low purity of raw materials and poor process control accuracy, the capacity of CR1620 battery manganese oxide decays rapidly at high temperature (55°C), and the cycle performance and storage performance are poor.

Due to its poor high temperature cycle performance, CR1620 battery manganese oxide is mostly used in capacity batteries such as mobile phones, tablets and other digital products. The market share of its application in power batteries is much smaller than that of CR1620 battery iron phosphate and ternary CR1620 battery power battery systems. CR1620 battery manganese oxide power batteries are currently used in pure electric special vehicles, plug-in hybrid buses and pure electric buses. Among them, BAIC New Energy has the most pure electric bus companies. In addition, bus manufacturers such as Xiamen King Long, King Long, Zhongtong Bus, and Yutong Bus have also begun to use CR1620 battery manganese oxide batteries.
