- Hydro-Québec is at the forefront of solid-state battery technologies.
- Solid-state lithium metal batteries have high energy density, last longer, are very light and potentially safer.
- Mercedes-Benz will help fast-forward testing in field conditions.
There’s been lots of battery technology and development over the last few years. All will agree that batteries are the EV’s X-factor and whomever comes up with the best battery will win. Solid-state battery technology is not new, in fact, Hydro-Québec developed a first-generation battery in the 1990s. Coming up with a truly usable product is now closer than ever thanks to Mercedes-Benz and Hydro-Québec combining their efforts.
Regular lithium-ion batteries continue to be the go-to type for all current electric vehicles. The reasons for moving away from them vary from environmental to safety, and packaging. Solid-state batteries do not require flammable liquid electrolytes and because they have high energy density, they need not be as large to provide as much range. This allows for a few things; one being cutting down on weight thus improving efficiency and providing far more range with a similar-sized battery pack.
Karim Zaghib, General Manager of Hydro-Québec’s center of excellence in transportation electrification and energy storage said: “We’re pleased to be partnering with Mercedes-Benz, an automotive company with an enviable reputation, to pursue our research even further. Our association will allow us to test new materials quickly in field conditions, and so accelerate the development cycle and respond to the concerns of automobile manufacturers.”
This is excellent news for all involved and we look forward to hearing more about the outcome in the future.
