According to IBM, the new design could outperform current lithium-ion batteries in cost, charging time (less than five minutes to reach an 80 percent charge), power density and energy efficiency. The battery is also less flammable, and it could be used in aircraft and smart energy grids, as well as electric cars and trucks.
The battery uses three new, proprietary materials, including a cobalt- and nickel-free cathode material and a liquid electrolyte. The unique combination is able to suppress lithium metal dendrites during charging, which lowers the chances that the battery will catch fire.
To move the new battery beyond the IBM Research Battery Lab, the team has partnered with Mercedes-Benz, battery electrolyte supplier Central Glass and battery manufacturer Sidus. While the team works out how to develop the battery, IBM Research will use AI to further improve battery performance and search for even safer, higher performing materials.
