- Samsung SDI, provider of electric vehicle batteries to OEMs such as Stellantis, Rivian, and BMW Group, have unveiled a new solid state battery in development for EVs.
- This battery pack, with double the energy density of a conventional lithium-ion EV battery pack, could enable a drivable range of over 600 miles, when fitted to EVs.
- The development comes after several other battery manufacturers also have plans to put solid state EV batteries into production.
New solid state EV battery from Samsung set to boost range further
Solid state batteries have been pinned as the next big step for EVs, allowing more energy to be stored within the same footprint, thanks to a higher energy density, and the opportunity to charge faster, and for a longer life. Samsung SDI’s new solid state example is no exception, and was unveiled at the SNE Battery Day in South Korea, earlier this month. The new pack manages an energy density of 500Wh/kg – near double that of a conventional lithium-ion EV battery’s 270Wh/kg. This will be good for a range of up to 1,000km per charge (over 600 miles).
Samsung SDI has pinned 2027 as the date that its solid state batteries will go into mass production, which will be initially aimed at the ‘super premium’ segment – so don’t expect to see its solid state batteries in the cheapest electric cars just yet. These new batteries potentially have large benefits for small EVs too, however. With more range being packed into a similarly sized battery pack, these compact electric cars could become just as versatile as larger models when it comes to road trips.
