Rechargeable lithium-aluminum/iron sulfide batteries for high energy density

A rechargeable lithium aluminum/iron sulfide battery has been built and tested. Prismatic LiAl/FeS cells provide a delivered energy to 80% depth of discharge (DOD) of 217 Wh/1 and a peak power of 375 W/l. Cycle life of over 365 cycles was achieved at the C/3 rate. Pulse self-discharge and driving cy...

Description
Summary:A rechargeable lithium aluminum/iron sulfide battery has been built and tested. Prismatic LiAl/FeS cells provide a delivered energy to 80% depth of discharge (DOD) of 217 Wh/1 and a peak power of 375 W/l. Cycle life of over 365 cycles was achieved at the C/3 rate. Pulse self-discharge and driving cycle tests were also performed for an electric vehicle application. The molten salt electrolyte requires an operational temperature of about 450 degrees C. A thermal control system composed of heating elements, thermal enclosure, and heat exchanger was engineered and tested. The components for a 8 kWh battery were developed and evaluated. This high temperature rechargeable battery is suitable for applications requiring high specific energy and minimal volume.< >
