Selenium cathodes have attracted considerable attention due to high electronic conductivity and volumetric capacity comparable to sulphur cathodes. Engineers have developed a simple and elegant method of producing high-powered lithium-selenium (Li-Se) batteries. However, practical development of lithium-selenium batteries has been hindered by the low selenium reaction activity with lithium, high volume changes and rapid capacity fading caused by the shuttle effect of polyselenides. Lithium is the key component of lithium-ion battery technology, which is becoming increasingly more prevalent in electronics. do not need to formally request permission to reproduce material contained in this Lithium-ion-storage behaviour of a Se@Co SA -HC cathode. with the reproduced material.

Although the idea of a Li–Se battery dates to the 1960s, over the past four years it has been revisited as a practical potential candidate for electrochemical energy storage. Li-Se battery technology is increasingly considered a real alternative to LIBs because of its high theoretical volume capacity and much higher conductivity. article provided that the correct acknowledgement is given with the reproduced material. Fig. Rechargeable lithium-ion batteries (LIBs) are considered the best hope for next-generation battery technology, thanks to their long-life cycle, high specific power and energy density. Mater.
