"We believe that range and efficiency are the new industry benchmarks for electric cars. Solid-state technology helps to cut down battery size and weight. This is why we are partnering with companies like ProLogium to ensure that Mercedes-Benz continues to break new ground in the automotive sector – for the benefit of our customers."
Vincent Yang, CEO and Founder of ProLogium said:
"We have been working with Mercedes-Benz on the testing of our EV battery cells since 2016 and are excited to strengthen and expand our partnership. We expect to work with Mercedes-Benz to demonstrate the effective application of our safe, high-performance solid-state battery cells to meet the Mercedes-Benz top quality standards. At ProLogium, we believe that innovative technology must be backed by the scalability of production. We look forward to ramping up our new plant by the end of 2022 and working with our customers toward successful mass production."
