AutoBeta(AutoBeta.net)04/26 Report--

The performance and life of power battery have been hindering the development of new energy vehicles. Now, with the iterative update of technology, power battery is expected to make a breakthrough in many aspects.

Recently, foreign media reported that Tesla CEO Elon Musk hopes to extend the service life of electric vehicle batteries to 1.6 million kilometers. Tesla's newly submitted patent is expected to accelerate the realization of this goal. The patent describes a new battery lithium process, which can not only improve battery performance, but also save costs.

Tesla filed a patent called "Nickel-Cobalt-Aluminum electrode Synthesis method", which revised the ratio of lithium to other metals, which will limit the formation of impurities in the heating process of battery materials. This process is helpful to the development of impurity-free single crystal nickel, cobalt and aluminum, and the new electrode combination enables the battery to achieve more than 4000 charging cycles.

According to the patent, the reduction of pollutants will help extend the overall life of the battery, helping Tesla take a big step forward in producing 1.6 million kilometers of batteries for his car. With the development of Tesla's battery technology, the service life of his electric vehicles may reach 20 to 30 years, even longer than ordinary gasoline-powered cars.

Earlier, a foreign Tesla car owner bought a Model S car in 2014, which took five years to drive to 1 million kilometers and set a Guinness world record. However, the vehicle has changed 3 times battery, 4 times motor, 2 times 12V battery, 1 time rear shock absorber, 1 time front axle, 1 time touch screen and so on. As the vehicle is still under warranty, the actual maintenance cost of the owner is 13000 euros (about 100000 yuan).

Of these, the first battery ran 290000 km, the second battery ran 250000 km, and the third battery ran 460000 km so far, and now the battery available capacity is still 86%.

Therefore, battery life is also an urgent problem for the long-term development of new energy vehicles. Tesla's new technology is expected to extend battery life to 1.6 million kilometers, which should be of great significance to the power battery industry.
