NASA develops electric vehicle batteries with twice the energy density of Tesla electric vehicles

NASA develops electric vehicle batteries with twice the energy Density of Tesla electric vehicles 



NASA reported that experimenters working within the frame of the Cutlasses( Solid- state Architecture Batteries for Enhanced Rechargeability and Safety) design have achieved an emotional result – they managed to make a traction battery with an energy density of 500 W h/ kg. This figure is further than twice the capacity of the traction batteries of ultramodern electric vehicles. 


Interestingly, NASA was doing exploration as part of its Convergent Aeronautics results design – that is, for aeronautics. still, new batteries may find wider operations. 

 

In the process of R&D, the specialists of the US space department managed to discover a new system of packing cells, which made it possible to reduce the mass of the battery by 30- 40 and double the energy density compared to current traction batteries. In comparison, the Tesla 4680 “ biscuit ” battery used in the Model Y has an energy density of lower than 300 Wh/ kg, while the energy density in the forthcoming CATL M3P phosphate batteries for the base Model Y is only 160 Wh/ kg. 


So what makes the SABERS battery so good? The thing is that in a promising NASA battery, the cells don't have individual packaging – they all fit simply on top of each other. This design isn't only lighter and further compact than the traditional design, it also demonstrates the continuity essential in moment’s solid- state batteries. Tests conducted by NASA have shown that Cutlasses can repel temperatures doubly as high as ultramodern lithium- ion batteries in electric vehicles can repel before bursting into dears. This makes it suitable for use in aircraft, where battery conditions are much more strict than in electric vehicles.
