At the “2015 China Rare Earth Hydrogen Storage Forum†held in Shandong at the end of August, Mr. Gao Jinliang, the hydrogen storage materials branch of China Rare Earth Industry Association, said that China’s hydrogen storage capacity is above 20,000 tons, and the market demand is below 10,000 tons. Seek significant. Since 2003, except for 2005 and 2010, China's hydrogen storage alloy market demand has reached 11,000 tons and 10,000 tons respectively, and other years are less than 10,000 tons. According to data from the China Chemical and Physical Power Industry Association, the market size of China's nickel-hydrogen battery in recent years is about 5 billion yuan, about 800 million US dollars, more than 800 million, and it is still shrinking. In 2014, the sales volume of nickel-metal hydride batteries in China was about 700 million, and the production and sales of nickel-cadmium batteries were estimated to be more than 300 million. Therefore, replacing nickel-cadmium batteries and alkaline-manganese dry batteries is one of the development directions of nickel-metal hydride batteries in China. At present, in the fields of power tools, personal care, toys, lamps, etc., the replacement of nickel-cadmium batteries by nickel-hydrogen batteries is obvious. Due to the limitations of nickel-cadmium batteries, relevant countries and regions have introduced restrictive policies. For example, China imposed a consumption tax of 4% on nickel-cadmium batteries from February 2015. The EU restricted its use from January 2016. It is estimated that the replacement of nickel-cadmium batteries by nickel-hydrogen batteries will increase the demand for hydrogen storage alloys by 1,000 tons per year.
