TUCSON, Ariz. – February 25, 2025 – Sion Power Corporation, a leader in next-generation rechargeable battery technology, today announced that Liz Rojewski has joined the company as chief operating officer (COO), effective February 17, 2025. She brings significant experience from a legacy automotive enterprise and innovative startup environments, having spent over 20 years in key innovation, electrification, autonomous mobility, and aftersales engineering roles at General Motors.

As COO, Rojewski will oversee Sion Power’s day-to-day operations, focusing on program execution and ensuring seamless team collaboration to meet commitments to partners as the company advances the commercialization of its Licerion® lithium-metal technology.
