65438+ 10 On June 5th, the first phase of the pilot project of Fujian Jinjiang Energy Storage Power Station (30MW/ 108MWh), the largest grid-side lithium-ion battery energy storage power station in China, was successfully connected to the grid for power generation, marking the application of limited zero attenuation batteries in contemporary Amperex technology.
The electrification of automobiles has entered the stage of high-quality development, and the network car is the top priority. With a life cycle of 800- 1 10,000 km, the requirements for endurance, endurance and other technical indicators are getting higher and higher. The benefits of developing zero attenuation batteries by contemporary Ampere Technology Co., Ltd. are self-evident.
In order to meet the needs of long-distance and continuous driving, Tesla also cooperated with Dalhousie University (Dalhousie? University) to develop advanced lithium-ion battery technology. The lithium-ion battery being developed by this university aims to prolong the battery life, improve the energy density and reduce the cost. ?
One of the most outstanding lithium ion researchers in the world, physicist Jeff? Led by Dahn, Dalhousie's research team described in a paper published in the Journal of Electrochemical Research Institute that this lithium-ion battery "can provide more than 6,543,800 miles of power for electric vehicles"? At the same time, the loss during use will not exceed 10% of the energy capacity. They found that the performance of this battery is obviously better than any similar lithium-ion battery reported before, and this battery may be suitable for self-driving taxi fleets and long-distance electric trucks.
The patent of this new lithium-ion battery technology applied by Tesla Motors Canada Branch last year is called "Dioxadone? And then what? Nitrile? Sulfite? As? Electrolyte? Additives? For what? Lithium-ion battery? Battery ",that is, using dioxolane and nitrile? Sulfite as an electrolyte additive for lithium ion batteries. After 1000 cycles, the service life of ordinary lithium-ion battery is still 95%, and the capacity of new battery is still amazing 90% after 4000 cycles.
