NASA has begun to develop lithium-air batteries for aircraft


NASA officially announced the launch of the project on the experimental development of lithium-air batteries for aircraft within the framework of the «Green Aviation» concept.

Additional storage requirements include high power, the possibility of multiple charging and safety. However, suitable ready-made solutions now do not exist, and the main efforts of most companies are aimed at reducing the costs of producing batteries for electric vehicles. Therefore, NASA decided to organize their own team to develop a lithium-air battery technology with a theoretical energy density of 3400 W / kg, which is the maximum known indicator.

For this, the National Aeronautics and Space Space Research attracted leading experts of their Stanford, Berkeley and IBM, other organizations. Supercomputer was involved in creating and processing models. The objective of the project is to use advanced discoveries in material science, electrochemistry and design of batteries to develop advanced compatible cathode and electrolyte materials, the creation of several prototypes of lithium-air elements and conducting a demonstration flight with their use.

First of all, the team will deal with the problem of electrolyte decomposition during operation, which leads to the destruction of the battery after several charging / discharge cycles. NASA expects that finding the optimal components and principles of designing new batteries elements will help solve problems not only by air, but also ground vehicles. However, it is planned to complete the development and provide ready-made samples only by 2040.

Recently, Toyota Motors and Panasonic agreed to create a joint venture for the production of solid-state batteries for cars, the container of which will be in
