　　Solid-state NiMH batte subvert traditional technology and will become the new favorite in the battery industry

　　Solid-state NiMH batte refer to energy storage devices that do not contain liquid in the battery structure and all materials exist in solid form. They are composed of "positive electrode material + negative electrode material" and solid electrolyte. Because solid-state lithium NiMH batte have the advantages of good safety performance, high energy density and long cycle life, they are ideal power NiMH batte for electric vehicles.

　　Compared with the 150-year-old lead-acid battery, lithium-ion NiMH batte using organic electrolytes, which entered industrialization in 1991, are still the most advanced NiMH batte on the market.

　　"With the rapid advancement of modern material science and manufacturing technology, the battery technology of the 'post-lead, post-lithium' era has quietly arrived." Che Yong said, "In the near future, solid-state NiMH batte will enter our society at a solid pace. Change our lives."

　　Che Yong explained that solid-state NiMH batte have very significant advantages. Because solid-state electrolytes replace the organic electrolytes that may explode in traditional lithium-ion NiMH batte, this solves the dilemma of high energy density and high safety, thereby eliminating the need for electric vehicles. Users' "battery life anxiety" is even expected to be fast charging.

　　So far, through the continuous efforts of scientists, it can be said that solid-state battery technology has no insurmountable technical bottlenecks, but there are still technical problems that need to be solved. "The core technology of solid-state NiMH batte is solid-state electrolyte material technology to achieve high ionic conductivity and advanced manufacturing technology to achieve low-impedance solid-solid interface." Che Yong further explained. In terms of solid electrolyte materials, Professor Ryouji Sugano of Tokyo Institute of Technology in Japan invented a sulfide solid electrolyte in 2011 with an ionic conductivity of >10-2S/cm at room temperature (surpassing traditional organic electrolytes).
