Mullen Issues Update on Its Solid-State Polymer Battery Testing

Battery Innovation Center (BIC) has completed the cell preconditioning in preparation for cell performance cycling. BIC will enter high rate cycling as part of the performance-based cycling with results forthcoming.

BREA, Calif., May 10, 2022– via InvestorWire – Mullen Automotive, Inc. (NASDAQ: MULN) (“Mullen” or the “Company”), an emerging electric vehicle (“EV”) manufacturer, an emerging electric vehicle (“EV”) manufacturer, announces today an update on Mullen’s solid-state polymer battery testing with the Battery Innovation Center (BIC) in Indiana.

Battery Innovation Center has completed the cell preconditioning in preparation for cell performance cycling. This is a C/20 preconditioning format to establish cell capacity baseline.  BIC will enter into high rate cycling as part of the performance-based cycling with those results forthcoming.

It is expected that this technology, when scaled to the vehicle pack level, will deliver a 150-kilowatt hour, solid-state battery able to 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 am pleased with the initial preconditioning results on our solid-state polymer battery cell and we’re progressing to the next stage of testing with BIC,” said David Michery, CEO and chairman of Mullen Automotive. “The battery has performed well and I’m looking forward to seeing finalized testing results from BIC later this month.”

“We are in process with Mullen’s cell and are looking forward to continued testing with final results due later this month,” said Ben Wrightsman from Battery Innovation Center.

The Battery Innovation Center will continue to perform the following tests on Mullen’s solid-state polymer battery, with final results expected in late May 2022. 

  • Constant Current Discharge Test

Testing to determine the effective capacity of a test unit using very repeatable, standardized conditions.

  • Peak Power Test

The purpose of this test is to determine the sustained (30s) discharge power capability of a battery at 2/3 of its OCV at each of various depths of discharge (DOD).

  • Constant Power Discharge Test

The purpose of this testing is to perform a sequence of constant power discharge/charge cycles that define the voltage versus power behavior of a battery as a function of depth of discharge. This testing characterizes the ability of a battery to provide a sustained discharge over a range of power levels representative of electric vehicle applications. Constant power discharges are similar to constant speed vehicle operation in their effect on a battery.
