How Does A 500 Mile EV Range Battery And A 1-Minute Charging Time Sound?
The carmaker Fisker Automotive, known for the electric luxury sports car Fisker Karma and going belly up because of battery production issues, has just filed a patent for what might be the next big leap in battery technology. Their patent claims that the new solid state lithium ion batteries can produce a 500 mile electric vehicle range and can be mass produced by the 2023 time frame. They also claim that the battery can be charged in as little as one minute.
According to Fisker, the radical new battery would deliver 2.5 times the energy density of typical lithium ion batteries. Solid State batteries differ from conventional batteries that use liquid organic solvent to transport charged particles back and forth. Instead the electrolyte is solid meaning there's reduced risk of leaking or igniting and that it can also last longer before losing its effectiveness.
What does this mean for the future of EVs? It means that Tesla won't be the only game in town when it comes to providing ridiculous ranges in electric vehicles. Given that Tesla also recently touted that their Semi Truck can offer a 500 mile range, on a full 80,000 net weight, we won't be surprised if other truck manufacturers also gets in the game with the availability of this forthcoming tech.
Logically speaking, the more reliable and long lasting battery should also boost research, development and ultimately production of electric vehicles across all the different manufacturers. From a mass consumer's perspective it isn't the extended range claim that should sound appealing, rather the ultra-fast 1-minute recharge time, which would eliminate the common limitation of today's electric vehicles: relatively slow recharge times.
Like most patents, we have to believe it until we see an actual working prototype outside of the laboratory setting. Once real world testing occurs a whole slew of factors take into account that may wildly affect the claims, for instance, temperature.
