SBIR-STTR Award

K2 Energy Solutions already produces a line of high power cylindrical cells that have found use in a number of Navy pulse power applications. We will adapt this existing cylindrical cell lithium iron phosphate technology to design and fabricate a large, 25Ah, hard-cased prismatic cell capable of matching or exceeding the high power capabilities and long calendar and cycle life achievable in small cylindrical cells.

Benefit:
The large prismatic cells to be developed in this project will find application in a broad range of commercial applications, including hybrid electric vehicles, large vehicle starter batteries, and battery back-up systems.

A high energy density, high power cylindrical cell suitable for pulsed power operation with a capacity between 15 and 20 Ah will be developed. The cell will utilize a lithium iron phosphate chemistry and will utilize both internal and external thermal management technology to minimize temperature rise even under high power operation.

Benefit:
Outside of the Navy high power application for which it is being developed, the proposed cell will find commercial application in hybrid electric vehicle applications.
