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.
