Tesla high nickel 4680 battery prototype has been used in vehicles

According to reports, Elon Musk said on Sunday that Tesla has been putting its high-energy density, high-nickel 4680 battery prototype into cars. Musk shared Tesla’s long-term goals for sustainable energy storage on BatteryDay last week, including a plan to equip high-energy vehicles (such as electric Semi and Cybertruck) with high-nickel batteries. Musk's plan is to accelerate the road to sustainable energy and transportation by studying how to make high-energy batteries with less or no cobalt, especially for vehicles that require more energy, and has won the enthusiasm of car fans. However, critics questioned why Musk did not show physical examples of the 4680 battery at the event, and it is not clear whether the comments on the strategy of using the 'diversified cathode approach' mean that it will use different cathodes in larger batteries. Format. Musk has now clarified that Tesla will produce high-energy cathodes for the 4680 battery (at least for now), and that these batteries have been used in vehicles in prototype form for several months. 'At least so far, we ourselves are only doing high-energy nickel. In addition, we have actually installed our battery box into a drivable car for a few months. The prototype is trivial and difficult to mass produce.' Musk did not say further. Vehicles using 4680 prototype batteries, although educated guesses may be that the Cybertruck that Musk had driven around Los Angeles may be one of them. As we all know, the prototype battery was manufactured at the Kato Road factory next to Tesla's Fremont electric car factory. Automotive engineer Sandy Munro said that even if it only uses the same chemical composition as the 2170 battery, Tesla can nearly double the battery capacity. Using 4680 batteries can also achieve other efficiencies, simply because the battery pack requires less steel, and because the 4680 desktop technology does not require cooling components between the batteries.
