Elon Musk Confirmed NEXT-GEN 4680 Battery! New Design, 3 Hidden Specs and Hit The Market SOON! P2. The first principle, the new 4680 gen 3 gets benefit from changing the composition of the battery materials.
The new 4680 gen 3 battery represents a major leap forward in battery technology and this advancement is driven by strategic changes in the battery’s material composition and structural design. These improvements not only enhance energy density but also contribute to cost efficiency and sustainability.

One of the most significant changes in the new 4680 gen 3 battery is the alteration of the cathode composition. The older generation 4680 gen 2 battery used an NMC811 cathode, consisting of 80 percent nickel, 10 percent cobalt, and 10 percent manganese. In contrast, the new battery employs an NMC955 cathode, with 90 percent nickel, 5 percent cobalt, and 5 percent manganese. This increase in nickel content is crucial because nickel-rich cathodes are known for their higher specific capacities, directly translating to greater energy density. By increasing the nickel content to 90 percent , the energy density of the new battery is significantly enhanced. Nickel’s higher specific capacity allows the battery to store more energy per kilogram, making it more efficient and capable of delivering longer ranges for electric vehicles.

Cobalt is an expensive and often ethically problematic material, with supply chain issues linked to human rights concerns. By decreasing the cobalt content, Tesla not only reduces the cost of the battery but also improves its sustainability profile. This change aligns with broader industry trends towards minimizing cobalt usage due to its high cost and ethical sourcing challenges.
Similarly, the reduction in manganese content from 10 percent to 5 percent further supports the increase in energy density. Manganese has a lower specific capacity compared to nickel, so decreasing its proportion allows for more nickel, thus boosting the overall energy capacity of the battery. These material optimizations make the 4680 gen 3 battery not only more powerful but also more cost-effective and environmentally friendly.
