Market Overview

Aviation batteries are a type of energy storage system, which provide dependable electrical power for aircraft use. They provide energy to start engines, for emergency back-up, for avionics, lighting, auxiliary power units and, as the primary propulsion source in electric or hybrid aircraft systems. Aviation batteries are designed to operate in extreme temperature, vibration, and pressure conditions with high energy density while still meeting safety requirements.

In aviation, the batteries used are lithium-ion, nickel-cadmium or newer solid-state chemistries, selected for their lightweight design and charged cycle life properties. Aviation batteries are critical to ensuring there is an available power source during flight operations, while also supporting the trends in electric aviation, unmanned aerial vehicles, and the development of more-electric aircraft to improve overall efficiency and environmental footprint.

Analysts' Viewpoint

The aviation battery sector is witnessing rapid expansion due to an increased use in electric and hybrid-electric aircraft, unmanned aerial vehicles, and the aviation sector's pursuit of carbon reduction and operating efficiency. Batteries are essential for providing power to primary propulsion systems, auxiliary power unit systems, emergency backup, and avionics.

The use of batteries is also increasing as the industry shifts to electric aircraft configurations and replaces mechanical and hydraulic systems. The aviation battery industry requires batteries with a low weight, a high energy density, and thermal stability, which are causing battery manufacturers to push innovation, performance and safety, and certification to ever-increasing boundaries.

The primary players in the market are investing heavily in research and development activities to improve lithium-ion and solid state batteries to increase their energy density and life. The completion of battery management systems, enhanced thermal control, and close coordination of battery manufacturers with aircraft manufacturers and regulators has facilitated implementation, certification, and commercialization.

Recent Developments

• In June 2025, Saft made public a collaborative co-development agreement with Safran to establish a high-voltage battery system for aircraft electrification and hybrid electric propulsion. The objective of the collaboration is a high energy density, modular battery packs, aircraft-grade safety features (thermal management, cell containment and redundancy) to enable more electric architectures and eVTOL/regional hybrid projects. This collaboration is an acceleration of industrialization which seeks to combine Saft's expertise in cell/module with aerospace systems expertise from Safran.

• In January 2024, NASA teamed with Archer Aviation to develop next-generation battery technology for electric aircraft- specifically its Midnight eVTOL air taxi. The focus of this engagement is on developing high-performance cells that provide high-energy density, high power capability, and safety to aviation standards, and that possibly can also serve space applications. NASA will publish most of the research, which will benefit the industry at-large. For Archer, it is helpful in de-risking its battery roadmap and supports its long-term goals of range, payload, and economic viability.

• In July 2024, EnerSys announced that they had reached an agreement to acquire Bren-Tronics (portable lithium battery/charger expert) for a purchase price of approximately US$ 208 Mn. The acquisition will bring a much stronger foothold in military and aviation portable power markets for EnerSys. As a note, the acquisition was presented as immediately accretive financially.
