Dow Launches New Phosphate Material For Improved Battery Performance

Dow Energy Materials, a business unit of The Dow Chemical Company, has developed a new phosphate-based battery material, Lithium Manganese Iron Phosphate (LMFP), which increases energy density by 10 to 15 percent in battery cells. As a result, this technology can enable energy storage systems to weigh less and require fewer cells, which in turn can lower cost.

"Energy density is the biggest single factor affecting electric vehicle (EV) battery performance," said David Klanecky, senior business director, Dow Energy Materials. "With the introduction of our new LMFP material, Dow is delivering solutions that meet the needs of our customers with next-generation technology."

The components that go into an advanced lithium-ion battery represent 30 percent of the total cell cost, leading the industry to pursue more efficient, cost-effective material solutions that can increase performance and lower the overall price of battery systems.

By increasing the amount of energy stored in the component materials, battery manufacturers can look to reduce the amount of space and volume needed for batteries, and increase the performance of systems. Using the new Dow technology, EVs could increase their range while utilities can achieve higher storage capacity.
