6 FAQs about [Amorphous silicon thin film battery components]
Are silicon thin-film anodes amorphous or nanocrystalline?
In general, pure silicon thin-film anodes can have either one of two possible structures namely: nanocrystalline or amorphous. Amorphous materials do not contain any long-range atomic ordering [ 111 ]. However, most pure thin-film anodes fabricated to date (and cited in this study) possessed an amorphous structure as given in Table 1.
What is the discharge capacity of a thin-film anode?
The amorphous silicon thin-film anode exhibited an initial discharge capacity of ∼3500 mAh g −1 and retained a capacity of ∼2000 mAh g −1 over 50 cycles, while the nanocrystalline silicon exhibited a discharge capacity of approximately 1100 mAh g −1 with only a ∼50% capacity retention after 50 cycles.
Are amorphous Si anode films cyclable?
Previous work has shown that amorphous Si anode films with thickness of up to 0.3 µm display high capacity and good cyclability (for instance, in our previous work 7, 8, 1st discharge capacity >3000 mAh g −1 and a capacity retention of ~85% after 100 cycles) in solid electrolytes 7, 8, 9, 10.
Is silicon a good anode material for lithium-ion batteries?
Silicon has emerged as a highly promising anode material for lithium-ion batteries (LIBs) owing to its high specific capacity and low voltage. However, previous research on silicon-based anodes has not adequately addressed inherent issues, leading to limited commercial applications on a large scale.
What are the different structures of silicon-based thin-film anodes?
Silicon-based thin-film anodes can have different structures as follows: Non-traditional structure silicon-based thin-film. While the above list indicates that a variety of silicon-based anodes have been investigated, the emphasis of this review will be focused on the continuous pure silicon thin-film anodes.
