Johns Hopkins University and the Toyota Research Institute have teamed up to research and develop better batteries. Utilizing new AI tools, the researchers tested combinations to determine what will work well and ultimately be a safe alternative to lithium ion batteries.

The research team focused specifically on using electrolytes for fluoride-ion batteries, an emerging alternative to lithium-ion batteries. Such electrolytes for batteries are not the type found in sports drinks, but the concept is similar. They’re both liquids containing charged particles, but while sports drinks include minerals natural to the body, battery electrolytes contain chemicals dissolved in a solvent that allows electrical charges to move through a battery.
