New solid-state silicon energy storage

What is an all-silicon solid-state battery?

Researchers from LG Energy Solution and the University of California San Diego have developed a new type of battery that combines two technological approaches. The battery has both a solid-state electrolyte and an all-silicon anode, making it an all-silicon solid-state battery.

Could a new silicon anode boost energy density?

Researchers hope that a new type of silicon anode will also boost energy density. Researchers from UC San Diego, supported by LG Energy, have made a promising discovery that involves two popular types of battery tech.

Can a silicon anode replace a liquid electrolyte in a solid-state battery?

The solution to both these problems is a special type of silicon anode in a solid-state battery, according to the US San Diego team. They eliminated the carbon and binders typically used in silicon anodes and replaced the liquid electrolyte with a sulfide-based solid electrolyte.

Are solid-state batteries a new territory?

“With this battery configuration, we are opening a new territory for solid-state batteries using alloy anodes such as silicon,” said Darren H. S. Tan, the lead author of the study and co-founder of the start-up UNIGRID Battery, which has licensed the technology.

Is solid-state silicon a viable alternative to conventional batteries?

“The solid-state silicon approach overcomes many limitations in conventional batteries. It presents exciting opportunities for us to meet market demands for higher volumetric energy, lowered costs, and safer batteries especially for grid energy storage,” said Darren H. S. Tan, the first author on the Science paper.

Could silver be a good material for a solid state battery?

“Previous research had found that other materials, including silver, could serve as good materials at the anode for solid state batteries,” said Li. “Our research explains one possible underlying mechanism of the process and provides a pathway to identify new materials for battery design.”
