Mullen Automotive Claims To Have Made Huge Advances In A Solid-State Battery

Solid-state battery technology is one of the long-term goals of the shift to electric cars. Mullen Automotive, an EV startup attempting to bring premium electric vehicles to customers, now claims to have achieved major advances.

The first edition 2024 Mullen FIVE EV will be powered by a standard lithium-ion battery pack, but the second generation will be driven by solid-state technology. Currently, testing is only taking place at the cell level, but pack testing is on the way.

“The test data collected shows an impressive outcome and future for solid-state batteries. To sum up, we tested our 300 Ah cell, which yielded 343 Ah at 4.3 volts, and the results surpassed all expectations. We can say with almost certainty that this technology, once implemented on the Mullen FIVE, will deliver over 600 miles of range on a full charge. The future is bright for Mullen Automotive,” stated David Michery, CEO and chairman of Mullen Automotive. 

Solid-state battery technology has the potential to help the whole electric vehicle sector. Depending on the size of the pack, these batteries guarantee a longer range, faster charging, and even less weight. Any electric car would benefit greatly from all of these characteristics. 

Weight loss improves a vehicle's dynamics quickly in all aspects, including accelerating, braking, and steering. In reality, the weight of performance-oriented battery-electric cars is now one of the most critical barriers. Mullen Automotive claims that during testing, they discovered the possibility for a 150-kilowatt-hour battery pack with a range of over 600 miles, as well as an 18-minute DC rapid charge with a range of over 300 miles. It would be a huge step forward if the Mullen FIVE ever made it to market with a true solid-state battery.
