- Tesla might introduce 4 new battery varieties for its next-generation fashions, together with the Robotaxi.
- The Cybertruck will reportedly get a brand new battery subsequent yr that makes use of “dry cathodes.”
- The battery timeline for the Robotaxi signifies it will not be accessible earlier than 2026.
- Silicon carbon anodes are below improvement to enhance vary and charging speeds.
Whereas Tesla is actually shifting its core focus away from electrical vehicles in the direction of synthetic intelligence and robotics, a brand new report means that battery improvement for its next-generation fashions and the Robotaxi is underway in full swing on the firm. The first objectives are improved efficiency, value discount, and mass deployment.
In line with The Data, which interviewed folks with direct information of Tesla’s future plans, the automaker plans to disclose 4 new variations of the 4680-type cells in 2026. The quantity denotes the diameter (46 millimeters) and size (80 mm) of the cells. They’re presently getting used within the Cybertruck and Mannequin Y.
The Robotaxi, which will probably be revealed on October 10, could possibly be geared up with one of many new variations of those batteries. The report claims that the Cybertruck may additionally get a brand new battery kind subsequent yr. One other new model of the 4680 cells utilizing silicon carbon anodes may additionally energy some future fashions.
Tesla now produces half one million 4680 cells each day, indicating it could have solved some manufacturing bottlenecks that restricted its mass deployment. Nonetheless, Tesla has struggled to make the subsequent era of those cells, referred to as 4680D, the letter denoting a brand new “dry” manufacturing course of.
In line with the Oak Ridge Nationwide Laboratory, the electrodes in conventional batteries use a moist slurry that is costly, dangerous to the surroundings, and takes up quite a lot of area on the manufacturing facility ground. The dry course of eliminates these poisonous solvents by mixing “dry powders with a binder,” which is a extra environment friendly and environmentally pleasant methodology.
Musk gave Tesla engineers an end-of-the-year deadline to determine mass manufacturing for the dry cathodes or scrap the 4680D plan solely. The goal additionally consists of decreasing the price of manufacturing of standard 4680 cells. The report provides that regardless of the low manufacturing yield for the dry cathodes, Tesla plans to introduce them within the Cybertruck subsequent yr.
There are 4 new variations of the 4680 cell that may use the dry cathode: NC05, NC20, NC30 and NC50 (NC means new cell). The NC05 will reportedly energy the Robotaxi. In line with the outlet, the cell will not be prepared for manufacturing until 2026, which suggests we’re nonetheless far off from the Robotaxi’s industrial deployment.

The extra energy-dense NC20 will energy an electrical SUV, the Cybertruck, and probably different future EVs.
The NC30 and NC50 will introduce silicon carbon anodes. In a battery, the anode is the constructive electrode. In line with some research, if it is made utilizing silicon carbon, it may well apparently maintain extra lithium, thus enhancing vary and charging speeds. The NC30 will apparently be put in in a future sedan and Cybertruck, whereas the NC50 will go into efficiency variations.
At current, Tesla buys most of its batteries from Japan’s Panasonic, China’s Up to date Amperex Expertise Ltd (CATL), and Korea’s LG Vitality Answer. Nonetheless, the automaker can be mass-producing its personal 4680 cells.
Musk beforehand mentioned mass-producing the 4680 cells would assist the automaker ship extra inexpensive vehicles. Nonetheless, the manufacturing ramp-up of the 4680 cells has been a nightmare. In line with the report, Tesla is shedding 70-80% of the cathodes—the damaging electrode in a battery—in take a look at manufacturing, whereas conventional battery makers lose solely about 2%.
2026 goes to be an important yr for a number of automakers, together with Tesla, as a number of new electrical vehicles priced below $30,000 are due for launch within the U.S. That features the Ford “skunkworks” EVs, the Kia EV3, next-gen Chevy Bolt EV and Tesla’s personal future inexpensive EV amongst many others.
With GM, Hyundai and Ford already slowly chipping away from Tesla’s EV market lead, which is down by greater than 10% this yr in comparison with final yr, battery improvement like this and extra vertical integration could be a approach for Tesla to proceed dominating the EV race down the road.
