Samsung is getting closer to solid-state battery production. Two separate divisions of Samsung will try to translate the new technology into real products. Samsung Electro-Mechanics intends to develop solid-state batteries for portable and mobile devices. Samsung SDI, on the other hand, is focused on developing solid-state batteries with sulfide electrolytes for the electric vehicle sector, writes The Elec.
Solid state batteries have a higher energy density, allowing you to store more energy in the same volume than traditional lithium batteries and also have a longer lifespan.
Samsung has been prototyping oxide-based solid-state batteries for over 10 years and is said to have made a breakthrough recently. As of May 15, Samsung Electro-Mechanics has filed 15 solid-state battery patents with the Korea Intellectual Property Bureau, while Samsung SDI has filed 53 patents. Samsung Electro-Mechanics’ solid-state battery patents published to date have mainly focused on ceramic-based solid electrolytes. Samsung SDI has focused on patent applications for solid-state batteries using sulfide-based solid electrolytes.
The manufacturing process for an all-solid-state battery is similar to the manufacturing process for multilayer ceramic capacitors (MLCC), a core product of Samsung Electro-Mechanics. It is likely that the research and development of Samsung Electro-Mechanics for solid-state oxide batteries will also be carried out at the Busan plant, which is currently mass-producing MLCCs. Since MLCC technology is similar to solid-state oxide battery technology in many aspects, it can be expected that solid-state battery commercialization will be possible soon in some cases.
With pilot production rumored to start later this quarter, Samsung SDI aims to:market leading solid state battery research and technologyAccording to The Elec, Samsung’s SDI division will install machines to manufacture sulfide-based cathodes and solid electrolytes. In March 2020, Samsung SDI unveiled a prototype-stage solid-state cell and a According to statements made at the time, batteries from such cells should enable a range of up to 800 km and 1000 charging cycles for electric vehicles.
According to SNE Research, Samsung SDI is ranked 6th worldwide with a market share of 4.5%. The market leader is CATL with a market share of 32.6%, followed by South Korea’s LG Energy Solution (20.3%) and SK On (5, 6%). Important customers in the automotive sector for Samsung are BMW and Stellantis. In the summer of 2021, there were reports that Samsung SDI would become one of the battery suppliers for Volkswagen’s electric vehicles.
