• Factorial Energy, a startup backed by General Motors, has developed a new type of battery technology that promises to be cheaper and more efficient than current electric vehicle (EV) batteries. The company's solid-state battery design uses a proprietary electrolyte material that allows for faster charging and higher energy density compared to traditional lithium-ion batteries. Factorial Energy claims its batteries can provide a range of up to 400 miles on a single charge, with the potential to reduce EV costs by up to 50%.

• The solid-state battery technology developed by Factorial Energy is designed to be a drop-in replacement for the lithium-ion batteries currently used in most EVs. This means that automakers can potentially adopt the new batteries without having to make significant changes to their existing vehicle designs or manufacturing processes. The company is currently working with several major automakers, including GM, to further develop and test its battery technology.

• One of the key advantages of Factorial Energy's solid-state batteries is their improved safety compared to lithium-ion batteries. The solid-state design is less prone to the thermal runaway issues that can lead to fires in some lithium-ion batteries, making the vehicles safer for consumers. Additionally, the company's batteries are expected to have a longer lifespan and require less maintenance than traditional EV batteries, potentially reducing the overall cost of ownership for EV owners.
