Samsung SDI, the Korean giant’s battery biz, on Tuesday promised EV batteries that can charge to 80 percent capacity in a mere nine minutes, plus models that can perform at that level for 20 years.
The ultra-fast charging battery will enter production in 2026. The long-lived product will start rolling off factory floors in 2029.
Samsung SDI teased the tech in March of this year. At the 37th Electric Vehicle Symposium & Exposition (EVS37) taking place this week in Seoul, it is also displaying an anode-free all solid-state battery (ASB) with a 900 watt-hour per liter density, which it eyes to start mass-producing in 2027.
After this announcement, many onlooked made agitations on the DSL Reports forum. But lets look at the. Possibility critically.
In practicals and as of the current state of EVs, we don't think that todays cars would last that long, but If quality bearings, front end parts, are used, twenty years is possible, or some 100,000+ miles before maintenance.
Bearing grease evaporates, so to speak, but there are cheap hub bearings, better quality ones, and bearings that didn't get enough grease when assembled.
Solid-state batteries are considered a significant step up from lithium-ion due to their higher energy density, faster charging capabilities and perceived safety as ASBs are less likely to catch fire.
Samsung's already tried to reduce the likelihood its kit catches fire, a live issue as Li-Ion-powered appliances and e-bikes spark domestic blazes that have regulators worried that low-quality products increase risks.
The Korean champ's approach is to use vents that exhaust heat and gas, so that if its batteries are involved in an accident or fire the chances of thermal runaway are reduced.
“New products from the company such as 46-phi batteries [a measure of battery diameter] are also part of the exhibition, along with a cell-to-pack (CTP) concept that increases energy density yet decreases cost,” stated Samsung.
The chaebol’s battery unit pitched the battery advancements as “super-gap” technology that will “pioneer the future global EV market.”
Improving battery performance is essential to advance the world’s transition to EVs. Many industry players are therefore working to improve the technology.
Samsung itself has even purchased part of a nickel mine to safeguard its supply chain for the raw materials needed to make batteries.
Japanese automaker Toyota has several battery undertakings, including in joint ventures with Panasonic. The company has claimed it is ready to roll out its solid-state-batteries with a range of 745 miles and charge time of 10 minutes by 2025.
