Lithium manganese oxide (LMO) batteries have higher specific power and thermal stability than LCO batteries, thus, they are used in medical instruments, portable power tools and some EVs like Nissan leaf .
The research team led by Professor Peter Slater has now shown recycled material from a cathode containing lithium manganese oxide (LMO) and nickel-rich ‘layered’ oxide (LO), can be upcycled to lithium manganese nickel oxides (LMNO) – a high voltage cathode material, which is attracting high levels of commercial interest.
2, as the cathode material. They function through the same intercalation /de-intercalation mechanism as other commercialized secondary battery technologies, such as LiCoO 2. Cathodes based on manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability.
LIBs are usually discarded near household waste and then placed in solid waste dumps, which can cause serious environmental problems; however, only 31.9 wt. % of spent LIBs were recycled by battery recycling industries (Golmohammadzadeh et al. 2018).

Lithium-ion batteries serve as a prominent secondary resource of lithium, but in the practice of LIBs recycling, lithium is not commonly recovered (Meshram et al. 2019). Batteries account for 27% of worldwide lithium consumption.
