Tesla patents next-generation battery

Company engineers claim that the battery will last for up to 1.6 million kilometers of travel.

A group of researchers at Dalhousie University in partnership with Tesla have recently tested a new lithium-ion battery featuring a monocrystalline cathode and a new advanced electrolyte. Developers assure that this new battery will serve drivers for up to 1.6 million kilometers of travel in an electric vehicle without any need for repair or replacement.

Tesla has applied for a patent on this invention together with the scientists who created it. 

The scientists are probably using the proven NMC532 material as a monocrystal for the cathode in the battery. Due to the large size of its grain, the new development is more reliable than standard NMC cathodes. 

The battery is constructed in a way that accommodates two electrolyte additives, which is a more reliable option than systems with three or more additives. 

The improved efficiency of the battery is achieved in part due to the optimal selection of cathodes and anodes for the specific electrolyte used in the device. 

Elon Musk has recently shared that Tesla will launch their own factory producing key battery elements. Until now, the company has been purchasing all the necessary components from Panasonic. If Tesla takes control over the entire production cycle, this will not only contribute to increased sales volumes, but also cut down on production time.
