Fisker patents breakthrough solid state batteries with 2.5 lithium ion energy density and one third the cost

Fisker makes luxury electric cars. They have filed a patents on breakthrough solid state batteries.

Fisker’s solid-state batteries will feature three-dimensional electrodes with 2.5 times the energy density of lithium-ion batteries. Fisker claims that this technology will enable ranges of more than 500 miles on a single charge and charging times as low as one minute—faster than filling up a gas tank. Fisker anticipates the technology to be automotive production grade ready from 2023 onwards.

Above – Fisker solid-state technology is capable of constructing bulk three-dimensional solid-state electrodes with 25 times more surface area than flat thin-film solid state electrodes and extremely high electronic and ionic conductivities, thereby enabling fast charging and cold temperature operation.

Current limitations in solid-state technology include low electrode current density, limited temperature ranges, limited materials availability, high costs and non-scalable manufacturing processes. Early results show that Fisker’s solid-state technology enables the construction of bulk three-dimensional solid-state electrodes with 25 times more surface area than flat thin-film solid-state electrodes and extremely high electronic and ionic conductivities—enabling fast charging and cold temperature operation.

Fisker’s battery delivers 2.5 times the energy density of typical lithium-ion batteries, with the potential of costing one third of the 2020 projected price of those batteries due to advances in materials and manufacturing.

Solid State batteries would also charge very quickly and should not have the fire issues with lithium ion batteries.

Toyota and Dyson are both planning to leapfrog Tesla with Solid state batteries in the 2020s.
