Thanks to CTOnews.com netizens Xiao Zhan cut, Mr. Aviation, Brother Black fly's left hand clue delivery! CTOnews.com, April 6 (Xinhua)-- according to CCTV News, Chinese scientists have developed the world's first hydrogen negative ion conductor that can transmit ultra-fast at room temperature.

According to the report, researchers at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences have developed the first case of hydrogen negative ion conductor that can be transmitted ultra-fast at room temperature, which can be used to develop a new type of battery different from lithium-ion battery. it is expected to bring a series of technological changes to areas such as energy storage and conversion.

The relevant scientific research results were published in the international academic journal Nature on the evening of April 5, Beijing time.

Hydrogen negative ion has the characteristics of strong reducibility and high redox potential. Hydrogen negative ion conductor has a broad application prospect in the fields of rechargeable battery and fuel cell, and it is a frontier topic in the field of clean energy.

According to the paper, Chen Ping, a researcher at Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Cao Hujun, an associate researcher team, put forward a new material design and development strategy, which created a large number of nanocrystals and lattice defects in rare earth hydride-lanthanum hydride lattice by mechanical ball milling, resulting in the distortion of lanthanum hydride lattice, thus significantly restraining the conduction of electrons and realizing the rapid conduction of pure hydrogen negative ions.

Previously, hydrogen negative ion conductors could only achieve ultrafast conduction at about 300 degrees Celsius, but this study achieved ultrafast conduction in the range of minus 40 degrees Celsius to 80 degrees Celsius, opening up a new way for the research and development of hydrogen negative ion conductors.

Structure of ▲ Lanthanum hydride LaHx sample according to Chen Ping, a researcher from Dalian Institute of Chemical Physics, Chinese Academy of Sciences, the scientific research team has now made an attempt to assemble hydrogen negative ion batteries, and on this basis they will develop next-generation materials with better performance to make them more practical.
