Inside the Tesla Model Y (4680 Structural) battery
The Tesla Model Y (4680 Structural) (2022) carries a 82 kWh NMC 811 Cylindrical 4680 pack with 3 modules at 355 V, weighing roughly 418 kg. Structural tabless format requiring specialised disassembly cells. High nickel yields offset elevated processing cost.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 94.2% | A — BESS ready | USD 4,607 |
| Year 4 | 89.9% | A — BESS ready | USD 4,425 |
| Year 6 | 85.6% | A — BESS ready | USD 4,162 |
| Year 8 | 81.3% | B — Second life | USD 3,674 |
| Year 10 | 77% | B — Second life | USD 3,281 |
What the chemistry means here
How it ages
Fade mechanisms mirror other NMC 811 cells. The tabless design lowers internal resistance and heat generation, which can slow resistance growth relative to older cylindrical formats.
Thermal behaviour
4680 cells carry the same high-nickel chemistry as 2170s but in a larger can with more energy per cell, so a single failing cell releases more heat. Structural packs also make it harder to isolate an individual failing cell during handling.
