Next-gen lithium metal EV battery project to focus on low cost

Technology News |
A $3.5M project is developing new membrane and anode technologies for low-cost lithium metal batteries in mobile applications.

The project includes 24M, Sepion Technologies, Berkeley Lab, and Carnegie Mellon University as part of the US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E).

24M’s core technology is semisolid lithium-ion, a new class of lithium-ion batteries that will be initially deployed in stationary storage. With this ARPA-E program, 24M and its partners will extend the capabilities of semisolid electrodes to ultra-high-energy density cells in mobile applicationsthat use lithium-metal anodes. The group has identified a new approach to stabilizing the lithium-metal anode, which, when combined with the inherent cost advantages of semisolid lithium-ion technology, can realize the energy-density promise of lithium metal, safely and at low cost.

A key application is higher density lithium battery cells for electric vehicles (EV) with lower costs. “As 24M nears commercial shipment of its first generation of energy storage products based on semisolid lithium-ion technology originally developed under ARPA-E support, we are excited to tackle a new grand challenge with partners Sepion Technologies, Berkeley Lab, and Carnegie Mellon University,” said Throop Wilder, CEO and Co-founder of 24M in a statement.

“We look forward to bringing our team’s innovations to market in a new class of safe, ultra-high-energy density, ultra-low-cost batteries that will propel the energy revolution and enable the holy grail of EV ‘range euphoria.’ By 2020 our battery costs will be less than $100 a kilowatt-hour (kWh). We’re emerging at the right time with the right technology.”

24M received its competitive award from ARPA-E’s Integration and Optimization of Novel Ion Conducting Solids (IONICS) program. The program seeks to advance storage technologies by focusing on the parts of the electrochemical cell that conduct ions and concentrates on solid materials because of the potential for greatly enhanced performance and stability.
