Mercedes-Benz & ProLogium Are Developing Solid-state Batteries

Battery technology is at the core of electric vehicles (EVs), and as a result, several manufacturers are experimenting with novel battery chemistry to improve range and safety.


One intriguing option in this search is the “solid-state battery,” which is why Mercedes-Benz has partnered with Taiwan’s ProLogium Technology to jointly develop solid-state batteries for automobiles, with the goal of developing a more reliable and long-lasting vehicle battery system.

At the moment, the majority of lithium-ion batteries sold are “liquid batteries” that use liquid electrolytes. As a result, if the liquid electrolyte spills, unintentional fires may readily develop.

Solid-state batteries are mostly composed of solid electrolytes. Along with the safety benefits, the energy density is quite high, extending the battery life of electric cars.

ProLogium’s primary focus is on silicon and lithium metal anodes, as well as bipolar solid-state batteries. Since 2016, it has been testing its own electric vehicle batteries with Mercedes-Benz.

Mercedes-Benz believes that range and efficiency will become the new industry standards for electric vehicles, and that solid-state battery technology can help reduce both battery size and weight. As a result, the company has chosen to collaborate with companies such as ProLogium to ensure that they continue to make significant advancements in the automotive field for the benefit of customers.
