Hyundai CRADLE and Ionic Materials to advance battery technology

Hyundai CRADLE is investing in Ionic Materials, a privately held battery developer based in Massachusetts, to advance the development of battery technology and improve electric vehicle (EV) performance with solid-state battery innovation.

Ionic Materials is developing advanced materials for high-energy-density batteries that are safer and less expensive than the current ones being used. The patented solid polymer material enables the production of solid-state batteries that are inherently safe, affordable, high in energy density and operational at room temperature. The polymer electrolyte properties also support lithium-ion cells with little to no cobalt in their cathodes.

Solid-state batteries are expected to eliminate safety issues with liquid electrolytes, enable higher energy anodes and cathodes and reduce the overall cost of the battery due to cheaper chemistries and manufacturing.

“This breakthrough technology could significantly improve battery technology,” said John Suh, Vice President of Hyundai CRADLE. “We are always looking for ways to ensure our cars provide the highest level of clean and efficient solutions. Our investment in Ionic Materials will keep us at the forefront of development, allowing us to build better eco-friendly vehicles.”

Further advancements made with the polymer will support additional high-energy and eco-friendly battery chemistries, including lithium metal, lithium sulphur and inexpensive and low-cost rechargeable alkaline batteries.

“The investment by Hyundai represents another key company milestone and demonstrates our rapid momentum as we develop polymer-based materials for solid-state batteries,” said Mike Zimmerman, Founder and CEO of Ionic Materials. “With the ongoing help of our investment partners, we have expanded our facilities and are adding to our team to meet the ever-growing demand for this technology.”
