Mercedes-Benz is making headlines with its modified EQS, currently testing a prototype lithium-metal solid-state battery. This cutting-edge innovation significantly elevates the vehicle's range from 488 miles to an impressive theoretical 621 miles.
Collaborative Development
The
Mercedes-Benz Centre for Competence for Battery Systems is collaborating with:
-
Factorial: A top-tier battery cell manufacturer
-
AMG High Performance Powertrain: Renowned for its expertise in Formula 1 technology
Together, they have developed a slightly modified EQS Sedan designed to deliver
25% more range compared to existing batteries of the same weight.
Key Innovations
- Power Density: Targeting 450Wh/kg
- Air Cushions: Volume-monitoring pneumatic actuators help safeguard the battery during thermal expansion and contraction.
Advantages of Solid-State Batteries
- Lighter and Safer: Positioned as the holy grail of battery technology.
- Rigidity Support: The solid electrolyte's stiffness poses a risk of cracking under stress; however, the air cushions mitigate this concern.
Mercedes anticipates further weight reductions and improved energy efficiency as testing progresses. Stay tuned for more updates as this exciting project unfolds.
Summary
Mercedes-Benz is testing a groundbreaking solid-state battery in its EQS prototype, aiming for an astonishing range of 621 miles. The collaboration with Factorial and AMG highlights significant advancements in battery technology, featuring special elements designed to enhance performance and safety.
