Are silicon-based negative electrodes suitable for all-solid-state batteries?

In all-solid-state batteries (ASSBs), silicon-based negative electrodes have the advantages of high theoretical specific capacity, low lithiation potential, and lower susceptibility to lithium dendrites. However, their significant volume variation presents persistent interfacial challenges.

Do silicon negative electrodes increase the energy density of lithium-ion batteries?

Silicon negative electrodes dramatically increase the energy density of lithium-ion batteries (LIBs), but there are still many challenges in their practical application due to the limited cycle performance of conventional liquid electrolyte systems.

What are ideal silicon negative electrodes for high-energy lithium-ion batteries?

Nature Communications 16, Article number: 4858 (2025) Cite this article Ideal silicon negative electrodes for high-energy lithium-ion batteries are expected to feature high capacity, minimal expansion, long lifespan, and fast charging.

Are silicon electrodes good for lithium-ion batteries?

Silicon electrodes promise high energy for lithium-ion batteries but face swelling and durability issues. Here, the authors develop a sieving-pore design that enables stable, fast-charging silicon electrodes with long cycle life, low expansion, and industrial-scale potential.

Does a SSC negative electrode have a Li + transport resistance?

The fitting results are shown in Supplementary Fig. 24 that the Li + transport resistance in SEI (Rint) of the SSC negative electrode (approximately 5–8 Ω) is almost unchanged at whole measurements, appearing to be smaller than that of the SC negative electrode (larger than 20 Ω and gradually increased) during the long-term cycling.
