UK-based OXIS Energy has announced it is partnering with Colorado-based Bye Aerospace to develop proof-of-concept advanced, lightweight lithium sulfur cells for Bye´s future electric aircraft, the company said.
The company will produce a common Li-S advanced battery cell for the high voltage battery pack system to achieve the higher energy density required for such aircraft. The project will commence in September 2019.
Bye Aerospace is working with OXIS on the Li-S battery cell characteristics to significantly improve eFlyer 4 and future air taxi aircraft designs´ performance.
In ground tests in Europe, OXIS has already shown that Li-S has demonstrated a significant improvement in simulated flight duration compared with Lithium NMC; it will now undertake a further series of tests which will provide a robust indication of the OXIS Li-S performance.
Over the next 18 months, the aim is to move towards the production of commercial cells and battery systems in order to meet the volume roll-out criteria set by Bye Aerospace.
OXIS Energy Ltd is involved in the design, development and now the move towards commercial production of lithium sulfur cells for battery systems. OXIS manufactures and produces all aspects and components in the making of the Li-S cell. With over 44 patent families, OXIS has been granted 183 patents with 101 pending.
Bye Aerospace is developing FAR 23-certified general aviation aircraft, starting with the eFlyer 2, for the flight training role. The eFlyer family of aircraft, featuring exemplary engineering, research, and electric aircraft solutions producing no CO2, are designed to answer compelling market needs.
