MENLO PARK, Calif., July 10, 2018 – Hyundai CRADLE, Hyundai Motor Company's corporate venturing and open innovation business, is investing in Ionic Materials, a privately held battery developer based in Massachusetts, to advance the development of battery technology and improve EV performance with solid-state battery innovation.

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

Expected Benefits of Solid-State Batteries:

•Inherent Safety: Eliminates safety issues with liquid electrolytes

•Higher Performance: Enables higher energy anodes and cathodes

•Lower Cost: Reduces battery cost through less expensive chemistries and manufacturing

'Ionic Materials' breakthrough technology could significantly improve battery technology today,' 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 battery development, allowing us to build better eco-friendly vehicles.'

'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.'
