Construction begins on trial solid-state battery manufacturing facility by SK On
In a significant stride for the electric vehicle (EV) industry, SK On Company has completed the construction of a pilot plant for test production of all-solid-state batteries (ASSBs) in Daejeon, South Korea.
Located around 140 km south of Seoul, the new facility is a testament to SK On's commitment to innovation and improvement in EV battery technology. The pilot plant is designed to contribute to the advancement of battery technology, specifically in the area of all-solid-state batteries.
The focus of the pilot plant is on the production of ASSBs, a type of battery considered to be the next generation of EV batteries. Unlike traditional batteries, these lithium-metal ASSBs offer improved energy-density, weight, and volume reduction. The new batteries will use lithium-metal anodes instead of graphite anodes, a significant departure from current technology.
The production process at the pilot plant will utilize a "warm isostatic press-free technology" for the first time in South Korea. This technology is expected to improve the energy density and performance of the produced all-solid-state battery prototypes.
Last year, SK On selected Solid Power Inc, a US-based all-solid-state battery technology developer, as its partner for the development and commercialization of all-solid-state batteries. This partnership aims to accelerate the development and commercialisation of ASSBs.
The new pilot plant marks a significant step forward in SK On's efforts to innovate and improve EV battery technology. In fact, SK On has announced plans to launch commercial production of ASSBs at a separate facility in 2029, a year ahead of its previously announced schedule.
The new technology could potentially lead to advancements in the EV industry, as the initial energy-density of the commercialized ASSBs by SK On is expected to be 800 watt-hours per liter (Wh/L), with plans to reach 1,000 Wh/L later on.
Meanwhile, the Just Auto Excellence Awards, a platform for recognizing achievements in the automotive industry, offers an opportunity for companies like SK On to stand out and be recognized for their contributions to automotive industry advancements. Entering the Just Auto Excellence Awards provides an opportunity to showcase achievements, elevate industry profile, and position oneself among top leaders.
In conclusion, SK On's new pilot plant is a significant step towards the development and commercialisation of next-generation EV batteries. The new technology, if successful, could revolutionize the EV industry by offering improved energy-density, weight, and volume reduction compared to traditional batteries.
