The industry is moving away from traditional lead-acid batteries towards advanced lithium-ion and other high-performance options. These new batteries are lighter and store more energy, which helps improve aircraft performance and reduce reliance on fossil fuels. The push for greener aviation and the development of electric and hybrid aircraft are also boosting demand for reliable, high-capacity batteries.

For instance, in October 2024, Saft, a battery manufacturer, introduced a new 28V lithium-ion battery for aviation use. This innovative battery packs more than double the energy for the same weight and 1.5 times the energy for the same volume compared to traditional lead-acid batteries. By adopting these lithium-ion batteries, aircraft can shed 20-30 kg of weight, resulting in less fuel use and lower CO2 emissions. Saft created this maintenance-free battery with its unique cell chemistry. Already, over 20,000 of these batteries are in use, proving their reliability even in tough conditions.

The aircraft battery market is shifting towards advanced, high-energy-density technologies such as lithium-ion and solid-state batteries. These innovations are set to improve aviation by enabling more sustainable and efficient flight operations. As the industry focuses on fuel efficiency and reducing carbon emissions, the demand for electric and hybrid aircraft is growing. This trend drives the need for lighter batteries with longer life cycles and faster charging capabilities.
