Tesla Patents a Battery That Can Last a Million Miles

Now the lifespan of Tesla’s drive batteries is about 400.000 miles or 650.000 km.

Canada-based Tesla’s division has received a patent for «Dioxazolones and nitrile sulfites as electrolyte additives for lithium-ion batteries.» The new components should increase the battery lifespan more than twice.

The new technology was invented by Tesla’s researchers and scientists at Dalhousie University in Canada.

The researchers created a prototype lithium-ion core with «a next-generation NMC single-crystal cathode and a new advanced electrolyte” that could operate in a battery for a million mile mileage.

NMC batteries contain a cathode with nickel manganese cobalt compound, whereas Tesla uses NCA batteries with nickel cobalt aluminum cathodes today.

According to unofficial data, NMC batteries will be used for the Tesla Model 3 in the Chinese market.

The current Tesla batteries function normally at least 160.000 miles (257.000 km) with a loss of about 10% of the original capacity.
