In the past few months, Liebherr-Aerospace has achieved a wide range of outstanding successes: Several strategic projects that our teams had been working on for years have materialized in this period. These include the award of a contract for a major flight control and actuation package on the 777X program by Boeing, and the foundation of a joint venture with Rolls-Royce for the power gearbox of their new UltraFan™ engine. And, these are only two examples from a long list of new contracts that we have concluded with air framer and operator customers that are detailed in this magazine. This recognition of our excellence in technologies, in manufacturing and in service honors our teams worldwide.We are convinced that our achievements are the result of not only our know-how and hard work, but also our determination to invest. Investment is not merely a buzz word for us, but it is something we are fully committed to. As Prof. Mirko Hornung from the German Research Institute "Bauhaus Luftfahrt" says in an enlightening interview: our world of aerospace is changing very quickly. Tomorrow's aircraft will be several miles ahead of today's machines in terms of speed, noise emissions and environmental friendliness. We are proud to say that the technologies, which will enable this tremendous progress, are being developed right now by our teams in Liebherr's centers of excellence worldwide.

The article considers a mathematical model of lithium-ion battery cell and battery (LIB) on its basis. The developed mathematical model allows predicting LIB temperature on different parts of its surface during charging and discharging by nominal and maximum currents. The results of the battery discharge process simulation and validation of the mathematical model based on the field experiment results are also presented
