Název v původním jazyce

A self-standing binder-free biomimetic cathode based on LMO/CNT enhanced with graphene and PANI for aqueous rechargeable batteries

Popis výsledku v původním jazyce

The electrochemical parameters of a novel binder-free self-standing biomimetic cathode based on LMO/CNT for Li-Ion aqueous batteries are improved using polyaniline (PANI) core-shell in situ polymerization and graphene. This constitution is created by combining three components as shown by a SEM and a TEM analysis: the graphene substrates support an entangled matrix of conductive CNT which connects islands of non-conductive inorganic material composed of lithium manga nese oxide (LMO). The electrochemical performances of the LMO/CNT-Gr/PANI composite electrode are optimized up to 136 mA h·g -1 compared to 111 mA h·g-1 of the LMO/CNT. Besides that, the new electrode shows a good cycling stability after 200 galvanostatic charging/discharging cycles, making this structure a future candidate for cathode materials for rechargeable aqueous batteries.
