MOTOROLA SOLUTIONS INVESTS IN MG-ION BATTERY COMPANY

Pellion Technologies, a startup commercializing magnesium-ion battery technology, announced an investment by Motorola Solutions. Because magnesium is divalent, it can displace double the charge per ion (i.e., Mg2+ rather than Li+). As an element, magnesium is much more abundant than lithium, and more stable. Magnesium-ion batteries theoretically could offer good electrochemical performance, while being safer and less expensive than Li-ion batteries.

Toyota, among others, has actively been exploring the development of Mg-ion batteries as a higher energy density solution for energy storage. However, Mg-ion batteries have suffered from a number of limitations, among them being anode/electrolyte incompatibility.

Pellion says that its next-generation technology enables novel, high-energy-density batteries delivering fully twice the energy of lithium-ion cells in a comparable weight and volume. Pellion’s batteries are now being tested in select demonstration devices in the mobile, wireless and robotics spaces.

Based in Cambridge, MA, Pellion was founded by a team of MIT researchers. In 2010, ARPA-E awarded the startup $3,204,080 to support the development of Mg-ion batteries for EVs.
