Samsung Electro-Mechanics has so far filed 14 patents that are seemingly related to solid-state batteries.

According to Kpris, an open portal of all patents filed in South Korea run by the Korea Patent Office, the component maker had so far filed a total of 14 patents related to solid-state batteries. 12 out of the total were filed between November and December of 2020.

Solid-state battery is a battery that uses a solid electrolyte instead of a liquid form that are used in commercial lithium-ion batteries today.

Using a solid electrolyte means the battery doesn’t require a separator between the cathode and the anode and is less prone to fires with increased energy density.

The patents reviewed by TheElec show that they are mostly focused on ceramic solid electrolyte.

Samsung Electro-Mechanics states in the patent registries that ceramic is more stable than polymer. It also explains the challenge ahead for the development of a ceramic solid electrolyte.

Last week, Samsung Electro-Mechanics CEO Chang Duck-hyun told reporters after the company’s shareholders meeting that the company’s main product multi-layer ceramic capacitors was ceramic and that it had technologies to make solid oxides at high temperature.

Samsung Electro-Mechanics was using these technologies to prepare components for a solid-state battery and green energy, Chang explained.

Meanwhile, Samsung SDI is filing patents related to solid-state batteries that use sulfide ceramic. According to Kpris, the battery maker has so far filed 49 patents that have solid-state in their name.
