Fisker Targets 2023 Launch for Solid-State Batteries

California-based electric vehicle specialist Fisker Inc. has filed a patent for a solid-state battery technology that promises greater energy density, faster charging times and longer driving ranges than are possible with current lithium-ion units.

Fisker says the new batteries will have 2.5 times the energy density of current lithium-ion batteries. The batteries will provide up to a 500-mile driving range and can be recharged in about one minute, the carmaker claims.

The solid-state systems also are expected to capitalize on advances in materials and manufacturing process to help cut costs by two-thirds of the 2020 projected price of conventional lithium-ion packs.

The new batteries promise to resolve previous challenges associated with solid-state batteries, such as cold-weather performance, electrode current density, materials availability and scalable manufacturing methods. Fisker says the technology enables the construction of solid-state electrodes with 25 times more surface area than flat, thin-film solid-state electrodes, and allows extremely high electronic and ionic conductivities.
