Aircraft Battery Market Global Report 2026

The aircraft battery market size has grown rapidly in recent years. It will grow from $0.94 billion in 2025 to $1.04 billion in 2026 at a compound annual growth rate (CAGR) of 10.3%. The growth in the historic period can be attributed to increasing aircraft production and deliveries, growing demand for reliable emergency backup power, rising adoption of advanced avionics systems, increasing aircraft fleet modernization, and stringent aviation safety and reliability requirements.

The aircraft battery market size is expected to see strong growth in the next few years. It will grow to $1.51 billion in 2030 at a compound annual growth rate (CAGR) of 9.8%. The growth in the forecast period can be attributed to increasing electrification of aircraft systems, growing adoption of electric and hybrid aircraft, rising demand for lightweight energy storage solutions, increasing deployment of next-generation lithium-ion batteries, and growing demand for high-performance batteries in advanced aircraft platforms. Major trends in the forecast period include advanced lithium-ion aircraft batteries, high-energy-density aviation batteries, battery thermal management systems, lightweight aircraft battery designs, and rapid aircraft battery charging technologies.

The growing production and deliveries of commercial and military aircraft are expected to propel the growth of the aircraft battery market in the coming years. Production and deliveries of commercial and military aircraft refer to the complete process of manufacturing, certifying, and supplying civil and defense aircraft to operators, reflecting the aviation industry's capacity to meet operational, regulatory, and strategic transportation and security requirements. A key factor driving the growing production and deliveries of commercial and military aircraft is the increasing demand for fleet modernization, as airlines and defense organizations seek more efficient, technologically advanced, and reliable aircraft to improve operational performance, reduce lifecycle costs, comply with evolving safety and environmental standards, and strengthen transportation and defense capabilities, thereby encouraging manufacturers to increase production capacity and accelerate delivery schedules. Growing production and deliveries of commercial and military aircraft increase the installation of electrical systems that require dedicated batteries for engine starting, backup power, and onboard operations, thereby supporting demand for aircraft batteries. For instance, in February 2026, according to ADS Group, a UK-based trade association, 2,175 commercial aircraft orders were placed in 2025, representing a 50% year-on-year increase, while 1,411 commercial aircraft were delivered, a 25% increase compared with 2024. Therefore, the growing production and deliveries of commercial and military aircraft are driving the growth of the aircraft battery market.

Major companies operating in the aircraft battery market are focusing on developing advanced battery solutions, such as certifiable battery modules, to improve energy storage safety, reliability, and integration into electric and hybrid-electric aircraft. Certifiable battery modules refer to aviation-grade battery units that have undergone regulatory testing to demonstrate their safety, reliability, and suitability for aircraft integration. For instance, in April 2026, H55, a Switzerland-based company specializing in certified electric propulsion and energy storage systems for aviation, delivered its first batch of Adagio battery modules to Smartflyer for integration into the SFX1 aircraft. The delivery supports the transition from component-level validation to full system integration and testing, including propulsion architecture and energy management. The Adagio battery system has completed regulator-required certification tests for integration across electric and hybrid-electric aircraft applications.

In October 2025, Archer Aviation Inc., a US-based aerospace and aviation technology company, acquired Lilium GmbH’s portfolio of approximately 300 advanced air mobility patent assets for €18 million ($20.84 million). Through this acquisition, Archer aims to enhance its next-generation electric aviation capabilities by integrating Lilium’s patented technologies related to battery management, high-voltage systems, electric engines, flight controls, propellers, and ducted fans into its expanding technology portfolio. Lilium GmbH is a Germany-based electric aircraft developer that provides high-performance aviation battery systems based on silicon-anode lithium-ion technology.
