Southern Californian emerging electric vehicle manufacturer Mullen Automotive has released an update on its next-generation solid-state polymer battery technology, which it says is a significant advancement over current lithium-ion batteries.
Mullen’s testing of its solid-state polymer cells reveals the potential for a 150-kilowatt-hour battery pack that delivers over 600-plus miles of range and highlights an 18-minute DC fast charge which can yield over 300 miles of range.
Mullen is working towards utilising solid-state polymer battery packs in its second generation Mullen FIVE model, with in-vehicle prototype testing set for 2025. Mullen’s first-generation FIVE, due in late 2024, is planned to launch with traditional lithium-ion cell chemistry.
Mullen is conducting research and development into a number of advanced battery technologies, including lithium-sulphur and lithium-iron-phosphate. Mullen’s goal is to deliver EV batteries that surpass today’s lithium-Ion technology and offer a host of benefits such as increased efficiency, energy density, and range while also lowering the cost, weight, thermal and environmental risks.
“We’ve conducted successful testing and will begin pack level development next,” said David Michery, CEO and chairman of Mullen Automotive. “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.”
Mullen has recently announced a string of key partnerships with hofer powertrain, Comau, ARRK, Dürr, and DSA Systems for EV powertrain, engineering, manufacturing, vehicle production systems, and over-the-air and vehicle system diagnostics, respectively.
The Company expects these strategic developments to play a crucial role in bringing the FIVE to market with the latest technology and in the shortest amount of time.
