Modeling the delamination of amorphous-silicon thin film
Sputter-deposited amorphous silicon thin films on metallic copper current collectors are widely studied as lithium-ion anode systems. Electrochemical results indicate these electrodes exhibit near theoretical capacity for first few cycles; however delamination at the thin film–current collector interface causes rapid capacity fade leading to poor cycling performance.

Are hydrogenated amorphous silicon thin-films suitable for lithium-ion batteries?
Therefore, hydrogenated amorphous silicon thin-films have demonstrated their suitability as an alternative for anodes in lithium-ion batteries. Our findings highlight that the PECVD technique offers the potential to explore various preparation conditions that can produce aSi:H films with high conductivities and low polyhydride contents.
What is a thin-film lithium-ion battery?
A thin-film lithium-ion battery , , , is one of the candidates for satisfying these demands. The lithium-ion (or rocking chair type) battery generally consists of intercalation compounds for both positive and negative electrodes as well as thin-film solid electrolyte.
What is a thin film battery?
Each thin-film battery component, current collectors, cathode, anode, and electrolyte, is deposited from the vapor phase. The final film, a protective coating, is required to prevent the reaction of the lithium from the anode when the battery is exposed to the air.
Can thin-film batteries be used with liquid electrolytes?
Thin-film cathodes and anodes tested with liquid electrolytes Only cathode films which are free of volatile components, binders and other additives, and are dense, smooth, and tightly adhered to the current collector are deemed to be plausible candidates for use in the all-solid-state thin-film batteries.
Are all-solid-state lithium batteries made of thin-film?
Recent reports of all-solid-state lithium batteries fabricated entirely of thin-film (<5 μm) components are relatively few in number, but demonstrate the variety of electrode materials and battery construction that can be achieved. More numerous are studies of single electrode films evaluated with a liquid electrolyte in a beaker-type cell.
Are smart windows a thin-film lithium-ion battery?
Electrochromic devices such as smart windows may be very similar in materials and operation to the thin-film lithium-ion batteries. Typical windows use a Li + ion or a H + ion electrolyte, either as a thin-film or a polymeric laminate material, whereas the electrodes are required to be submicron-thin-films for spectral reasons.
