Foreign university experts develop the first Nickel Hydride No. 5 batteries

　　According to reports, scientists at the University of Illinois at Chicago (UIC) have recently developed and designed a fully rechargeable lithium-carbon dioxide battery that can maintain stable performance after 500 charges and discharges and overcomes two major problems. Technical barriers.

　　According to experts, the performance and energy density of the lithium-carbon dioxide battery they developed will be seven times higher than that of currently commonly used lithium-ion batteries. It turns out that current lithium-ion batteries have some problems with their performance and stability after repeated charging and discharging.

　　A University of Illinois at Chicago (UIC) research team found a way to solve this problem and developed this lithium-carbon dioxide battery, the characteristics of which are described in an article titled "Carbon-neutral long-term battery" published by the industry media "Advanced Materials". Efficient lithium-carbon dioxide battery" was described in the paper.

　　Solve the problem of carbon deposits

　　Alireza Ahmadiparidari, the lead author of the paper, said that one of the main problems we encountered in developing this battery was the large accumulation of carbon on the battery catalyst after the energy storage system was discharged. This process eventually caused the battery to fail. The accumulation of carbon not only prevents the activity of the catalyst, but also prevents the diffusion of carbon dioxide and triggers the decomposition of the electrolyte in the charged state.

　　To solve this problem, the team used molybdenum disulfide nanoflakes as a catalyst in the battery cathode material and a hybrid ionic liquid/dimethyl sulfoxide electrolyte material, which they say helps incorporate carbon into the cycling process Neutralize and prevent damaging performance, and ultimately achieve breakthroughs.

　　said Amin Salehi-Khojin, associate professor of mechanical and industrial engineering at the University of Illinois at Chicago (UIC). Our unique combination of materials helps create a carbon-neutral lithium carbon dioxide battery with higher efficiency and longer cycle life.

　　Although the paper relies on theoretical calculations to describe the reversible operation of this battery, the team appears confident in its development and applications.
