Cathode materials

…Currently studied cathode materials for RAZIBs report promising initial battery capacity (>250 mA h g-1) and operating potential (ca. 1.5 V vs Zn/Zn2+); however, the battery cells suffer from severe capacity loss when cycling at practical rates (C-rate < C/2), hampering the commercialization of RAZIBs. Therefore, the development of RAZIBs as a tech

Mariana Kneppers, Patrick Walter and Neil Withers compare competing cathode materials for electric-vehicle batteries and the tradeoffs among cost, safety and performance. They also discuss a photocatalyst that uses spent car-battery acid to help convert plastic waste into useful chemicals.
