Mullen Automotive announces impressive solid-state polymer battery test results

Results from Indiana’s Battery Innovation Center (BIC) shows Mullen Automotive’s solid-state polymer battery cell testing exceeds previously stated values of 300 Ah (ampere-hour) at 3.7 volts.

Mullen Automotive, Inc, an emerging electric vehicle (EV) manufacturer, announces results of Mullen’s solid-state polymer battery testing with the Battery Innovation Center (BIC) in Indiana. Testing results from BIC show the solid-state polymer cell, rated at 300 Ah and 3.7 volts, tested in at 343.28 Ah at 4.2 volts, exceeding expectation and in line with test tolerance from previous EV Grid test results.

Testing conducted at Battery Innovation Center (BIC) in Indiana, show Mullen’s solid-state polymer cell coming in at 343.28 Ah at 4.2 volts, which is in line with previously quoted test results from EV Grid. In EV Grid’s testing, the solid-state battery cell was rated at 300 Ah at 3.7 volts, with the battery yielding 343 Ah at 4.3 volts. The test data collected from both BIC and EV Grid have exceeded expected test tolerance and show an impressive outcome and future for solid-state batteries.

It is expected that with this technology, when scaled to the vehicle pack level, a 150-kilowatt hour solid-state battery can deliver over 600 miles of range on a full charge for the Mullen FIVE EV Crossover. In general, solid-state batteries offer higher energy density, faster charging time, smaller size and safety compared to traditional lithium-ion cells.

“I’m impressed with the ongoing performance of the solid-state cell after going thru multiple intense testing sessions from accredited testing facilities,” said David Michery, CEO and chairman of Mullen Automotive. “The battery has performed exceptionally well, and I’m pleased with the results from BIC in Indiana.”

“We are pleased to see that the results from on-going testing are in-line with those previously notated,” said Ben Wrightsman, president and CEO of Battery Innovation Center. “The cell thus far has performed as stated, and we will continue to test additional parameters to characterize the overall capabilities and performance.”

Mullen recently announced the “Strikingly Different” U.S. Test Drive Tour, covering 19 cities across the U.S. The tour will begin this fall in Southern California and work its way throughout the U.S.
