EnerDel to Invest $3.3M in Battery Research

Funding is to find way to eliminate overcharging in lithium-ion cells.

Published: 23-Jun-2009

Battery maker EnerDel, Inc. will invest $3.3 million in a research project to develop a technology to eliminate overcharging in lithium-ion cells.

The funds - obtained from the Department of Energy's Vehicle Technologies Program last month - will be allocated for the development of a new chemical additive that acts as a "shuttle agent" to effectively cap the voltage of the cell. The additive transports the charge through the cell once the desired voltage is reached.

"Overcharging cells in pack systems is normally monitored with voltage monitoring circuits. Refining this at the base chemistry level of the cell will vastly improve reliability and overall pack efficiency," the company said in a statement.
