Batteries for Aviation Industry and their Bonding Techniques

Abstract

Nowadays, the development of hybrid and full electric aircrafts is gaining more and more attention, due to environmental consciousness. Currently the limited capacity of energy storage systems allows for relatively small flight distances for these airplanes. After a brief introduction, the paper introduces the internal structure of the battery bank. Then, we compare the relevant the battery chemistry and the key packaging parameters of today's most used battery types, especially those that are aviation relevant. Based on the critical review of literature data and engineering practice, the best option is to create a battery pack for aircrafts that consists of many (typically several hundred) small capacity (some Ah) cells, by connecting them in parallel and series. Finally, our study also presents several potential cell bonding technologies and compares the materials used by these processes. The work is supported by the EFOP-3.6.1-16-2016-00014 project, entitled “Research and development of disruptive technologies in the area of e-mobility and their integration into the engineering education”.
