Having been used in aviation for decades, lead-acid batteries have a well-established reputation for reliability. Their performance is predictable, which is crucial in aviation, where safety is paramount. The technology is mature, and extensive testing has validated its suitability for aircraft applications. 2.3. High Surge Capacity
All other lithium metal cells and batteries can only be shipped on a passenger aircraft under exemption issued by all States concerned. Lithium-ion batteries (also abbreviated as Li-ion batteries) are secondary (rechargeable) battery where the lithium is only present in an ionic form in the electrolyte.
It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
Comparison of lithium-ion battery chemistries for aviation. Despite continued improvements, lithium-ion batteries remain inadequate for long-range electric flight. The energy densities achieved today are still far below the 800 Wh/kg threshold projected as necessary for viable commercial aviation applications .
By highlighting trade-offs, application-specific requirements, and research gaps, this work aims to guide the development of viable battery-powered and hybrid-electric aircraft systems for
