6 FAQs about [Microscopic mechanism of battery charging]

What happens during the charge-discharge process in rechargeable batteries?

Here, electrode volume change, mechanical deformation, dendrite growth, electrolyte degradation and SEI formation are all typical examples during the charge-discharge process in almost all current rechargeable batteries.

What mechanisms dominate Li + storage in battery electrodes?

Intercalation, alloying and conversion reactions are three typical mechanisms generally recognized to dominate Li + storage in battery electrodes. These reactions direct the charge storage of electrode materials differently, leading to distinct electrode capacities, morphology and structures [3, 144].

What are the charging processes in Li-O 2 cells?

The charging processes in Li-O 2 cells include the evolution of SEI, the competition of the oxidative decompositions of various species (e.g., Li2 O 2 and Li 2 CO 3), and the pore-clogging issue in the porous composite electrode.
