Development and Test of Safe, High Power Lithium Ion Main Batteries for General Aviation Aircraft

Standard Details

Advanced chemistry batteries may help reduce weight and increase aircraft performance. Lithium Ion chemistries' high energy density enables 40% weight savings over existing baseline, Lead Acid and Nickel-Cadmium (Ni-Cd) batteries. Baseline requirements for Lithium Ion batteries were developed by studying Cessna's aircraft product line. Nanoscale phosphate-based Lithium Ion cathodes improve safety through inert failure modes, while delivering higher power over conventional oxide-based Lithium Ion and baseline chemistries. Cells and batteries were tested under selected load, environmental, and temperature conditions using procedures adapted from RTCA DO-293 and DO-160. On-board aircraft testing verified performance compatibility. Safety tests verified inert failure mode and flight environment compatibility. Test results showed nanoscale phosphate Lithium Ion batteries are promising as a safe, high power Lithium Ion main battery in general aviation aircraft.
