We’ve been listening to about solid-state battery breakthroughs for a decade, or greater than a decade really. Stable-state batteries are the way forward for batteries, and the way forward for EVs — as they’ve been for a number of years. Given the numerous bulletins on solid-state battery breakthroughs and solid-state batteries being the long run, it’s exhausting to get enthusiastic about any incremental information on these. Nevertheless, SK On is attempting to get us to consider and get excited once more.
“SK On, a leading global battery and trading company, today unveiled its latest research and development (R&D) achievements on all-solid-state batteries (ASSBs) as the company reinforces its commitment to drive innovations in next-generation battery solutions,” the corporate wrote final week.
Briefly, SK On analysis tasks just lately obtained papers revealed in scientific journals, and the corporate filed a number of patents on solid-state battery developments. However that doesn’t actually inform us a lot. That type of factor is going on on a regular basis with expertise that isn’t going wherever commercially.
Getting technical, right here is the one SK On is most enthusiastic about: “SK On’s study with Dr. Jin Ho Kim’s group at Korea Institute of Ceramic Engineering and Technology focuses on the use of ultrafast photonic sintering* technology in the manufacturing of oxide-rich inorganic-organic composite hybrid solid electrolytes. It is regarded as groundbreaking for applying photonic sintering technology, traditionally used in printed circuit board manufacturing, to the development of ASSBs. * Photonic sintering: A process that uses intense light energy applied instantaneously to strengthen the bonding of powder particles, resulting in a solid mass with enhanced strength, durability and improved material properties.”
Effectively, it sounds fancy. However inform me the EV mannequin it’s going to be utilized in.
Perhaps I’m being too cynical and detrimental on this. R&D takes time, and progress is usually incremental moderately than revolutionary.
If you happen to’re curious about studying extra about what the corporate has been engaged on within the lab, you’ll be able to read more details on the R&D here. So far as long-term plans for industrial software, SK On writes, “SK On is developing two types of ASSBs: polymer-oxide composite and sulfide-based, with commercial prototypes expected by 2027 and 2029, respectively. The company’s solid-state battery pilot facility, currently under construction at its research center in Daejeon, Korea, is set for completion in the second half of 2025.” So, that’s the place we’re. Nothing to get too enthusiastic about, however solid-state battery R&D continues to maneuver ahead.
