Silicon Energy Battery Application Technology

What are the applications of silicon-based anodes in lithium-ion batteries?

In summary, we introduce the applications of silicon-based anodes along with the development of Li-ion batteries, from liquid electrolytes, gel-electrolytes, to all-solid-state electrolytes. Silicon-based anode materials play an important role in the application of lithium-ion batteries.

Can liquid electrolyte batteries be used with silicon-based anodes?

In the application of liquid electrolyte batteries with silicon-based anodes, it is important to develop the electrolyte system suitable for silicon anodes, and improve its film-forming properties so that it can form a relatively stable SEI film on the silicon surface .

Why is silicon based anode a good choice for a battery?

The semiconductor nature offers silicon anode good chemical stability in the electrolyte, which greatly improves the safety of the battery, and the abundance of silicon in the earth crust (25.8%) allows its application at a low cost . However, there are some challenges before the practical application of silicon-based anodes.

Are silicon oxides a promising material for lithium-ion batteries?

Choi, J. W. & Aurbach, D. Promise and reality of post-lithium-ion batteries with high energy densities. Nat. Rev. Mater. 1, 16013 (2016). Liu, Z. et al. Silicon oxides: a promising family of anode materials for lithium-ion batteries.

Will silicon-based anode lithium-ion batteries enter the Fast Lane?

Therefore, we believe that the process of commercial application of silicon-based anodes from liquid to solid state has now begun to enter the fast lane, and silicon-based anode lithium-ion batteries with higher energy density and higher safety will be launched.

How will silicon-based anodes and solid-state electrolytes affect lithium-ion batteries?

The use of silicon-based anodes and solid-state electrolytes will bring the energy density of lithium-ion batteries to a new level. Common solid-state electrolytes that match silicon can be divided into oxide electrolytes, sulfide electrolytes, and polymer electrolytes (Fig. 9).
