Rare Earth Hydrogen Alloy Electrode for New Energy Storage

Baotou Zhongke Xuanda New Energy Technology Co., Ltd. (hereinafter referred to as Zhongke Xuanda) establishes stable production of new rare earth hydrogen alloy electrode materials for energy storage with independent intellectual property rights in domestic. The process and product control system, as well as the products, are highly valued by various power battery manufacturers, according to the information of Baotou Rare Earth High-tech Zone.

The global hydrogen energy layout is accelerating. From the perspective of energy development laws and influencing variables, the hydrogen energy industry has entered a new stage of development. During the "14th Five-Year Plan" period, our country accelerates the development of hydrogen energy industry chain technology and equipment such as green hydrogen production, storage, transportation and application, and promotes the development of the hydrogen fuel cell technology chain.

By 2050, the global hydrogen energy will account for about 18% of the total energy, and the output value of the hydrogen energy industry chain will exceed 2.5 trillion US dollars. With the continuous investment in technology R&D and industrial capital, the global hydrogen energy industry will Usher in a period of major opportunities for rapid development.

Professor Han Shumin from Yanshan University said that the commissioning of the production line of new rare earth hydrogen alloy electrode materials is a crucial attempt in the combination of new material R&D and preparation technology and hydrogen energy application, and points out an important direction for the future development of hydrogen energy in our country.

The energy crisis is a huge challenge that will be faced in the middle of this century. Per statistics, if the world's proven energy sources are exploited at the current level, coal resources can still be exploited for 100 years, oil for 30-40 years, and natural gas for 50-60 years.

On the other hand, the ecological crisis has become a huge challenge facing today's society. The harmful substances produced when fossil fuels are burned seriously pollute the environment, leading to many ecological problems such as the greenhouse effect, global warming, reduction of biodiversity, desertification, etc., which seriously affect resource security and sustainable social and economic development.

As a secondary energy source with a wide range of sources, clean, carbon-free, flexible and efficient, hydrogen has rich and extensive application prospects in the fields of automobiles, rail transit, ships, aerospace, logistics, power supply. This new type of hydrogen storage technology is considered to be the most promising hydrogen storage method.

Rare earth magnesium-nickel-based hydrogen energy storage alloy battery is a new type of secondary battery with hydrogen storage alloy as the negative electrode material. It is known as green energy. It is widely used in various small portable devices. However, the high self-discharge rate causes certain difficulties for the practical application of batteries.

The R&D team of Zhongke Xuanda has realized the precise control and safe operation required by the large-scale production of alloys by improving the Mg feeding method and production process. The electrochemical capacity of the prepared alloy is greater than 360mAh/g, the life could reach more than 500 cycles. The alloy has the advantages of low-temperature performance and low self-discharge performance. It is well performed than the currently commercialized mixed rare earth AB5 alloy electrode material.

The new rare earth hydrogen alloy electrode significantly improves the performance and market competitiveness of Ni/MH power batteries, showing good market application prospects, and can be used in fields such as new energy vehicles, smart grid energy storage, and communication base station reserve power supplies.
