New Samsung all-solid-state battery patent reduces ignition risks

Samsung (Electro-Mechanics) has filed 14 all-solid-state battery patent with the Korean Intellectual Property Office including the term ‘all-solid-state’ in the title of the invention, discovered by Cypris. The patents that have been disclosed so far are those applied until the end of 2020.

Of the 14 all-solid-state battery patents filed by Samsung, 12 were filed between November and December 2020. At the end of December 2020, there were 11 applications. Since patents are generally published 1 year and 6 months after filing, patents filed at the end of 2021 will not be published until July this year.

By July this year, when the patent filed at the end of 2021 would also be disclosed, Samsung Electro-Mechanics’ direction for developing all-solid-state battery components is expected to materialize. At the shareholders’ meeting last week, an official confirmed: “developing small all-solid-state battery parts.”

All-solid-state battery

• An all-solid-state battery is a battery in which the electrolyte between the positive and negative electrodes of the battery is changed from liquid to solid.

Since the electrolyte is not liquid, there is no need for a separator between the anode and cathode, and compared to lithium-ion batteries currently in use, the risk of battery ignition can be reduced and the energy density can be increased.

After the regular shareholders’ meeting on March 15, President Jang Deok-hyun told reporters that “the multilayer ceramic capacitor (MLCC) that Samsung Electro-Mechanics makes well is a ceramic product, and (Samsung Electro-Mechanics) has the technology to make it into a solid oxide at high temperatures.”

He added, “based on this technology, we are preparing small all-solid-state batteries or parts for green energy. I will take a separate time to explain when I’m at the point of making a prototype (prototype).”
