In September, Canadian scientists from the University of Dalhousie published a patent for a new battery that they developed for Tesla. This is a lithium-ion battery with a single-crystal cathode and an advanced electrolyte, which should be enough for an electric car of 1.6 million kilometers.
Judging by the text of the patent cited by Electrek, it is a question of a new battery system with fewer effective electrolyte components.
The car company has filed an application through its Canadian division for an international patent, dubbed “Dioxazolones and Nitrile Sulfites as Electrolyte Supplements for Lithium-Ion Batteries.”.
The new system can be used in various devices for storing energy, for example, in batteries for cars or for power systems. In particular, these additives increase the performance and life of lithium-ion batteries, and reduce overall manufacturing costs.
A new mixture in an electrolyte solution can be used with nickel-magnesium-cobalt, which is usually used in the production of electric vehicles by other companies. Previously, Tesla used this material to create industrial batteries, but in automobiles it used nickel-cobalt-aluminum (NCA). Perhaps a new patent will change the situation.
