ALD and MLD Surface Coatings for Performance and Safety Enhancement of Li-Ion Batteries

Interfacial surfaces have commercial plagued battery development causing both reduced lifetime and safety concerns. Despite continuous improvements in capacity and stability for electrodes in both liquid and solid-state lithium-ion batteries, ionic conductivity, dissolution, decomposition, and solid electrolyte interphase (SEI) formation often limit the ability for new materials to be commercially implemented. One commonly implemented method is to apply a thin surface coating.
