The electric car market is growing along with all the big-name releases from the auto industry like Tesla, Rivian, Ford, among others, and we need better batteries to keep up with this production.

At this week’s IDTechEx conference, startups showed their new technologies (and possibilities) for the new batteries coming to the market. Improvements include cost, range, lifespan, speed, reload, and reduce risks of use. As described by the Road Show, the most significant development is the kilowatt-hour power density that can be stored in the battery. This change can extend the full range of features.

An example of the need for a larger number of batteries production is that Ford could only put 50,000 Mustang Mach-E on sale because of the number of batteries currently available on the market. Tesla manufactures its batteries so you can always have control over this availability. BloombergNEF forecasts say that sales of electric vehicles will increase from 2 million in 2018 to 10 million by 2025.
