The battery in the 2023 Tesla Model Y varies by region and trim, but most US models use nickel-rich NCA chemistry in a 2170 cell format, while Chinese and some other markets employ CATL’s LFP chemistry for standard-range versions.
Battery chemistry and cell formats in the 2023 Model Y
The North American 2023 Model Y Long Range and Performance models typically use 2170 cylindrical cells with nickel-rich NCA (nickel-cobalt-aluminum oxide) chemistry, assembled into a large battery pack by Tesla (with Panasonic as a primary supplier for these cells). This configuration emphasizes higher energy density and EPA-rated range.
Regional variations and supplier differences
Battery chemistry and cell format differ by market and trim. In China and some other regions, the Standard Range Model Y commonly uses CATL’s lithium iron phosphate (LFP) chemistry in a smaller ~55–60 kWh pack. LFP cells offer lower energy density but longer cycle life and lower cost, which fits the needs of standard-range models in those markets.
Before listing the key configurations, note that some newer production lines and trims have experimented with different cell formats, including occasional use of 4680 cells in limited builds or pilot programs, potentially with a different structural pack design. Suppliers can also vary by production location and quarter.
- United States (Long Range and Performance): 2170 cells with NCA chemistry, primarily from Panasonic, in a high-energy-density pack.
- China and some other markets (Standard Range): CATL LFP chemistry in a ~55–60 kWh pack.
- Limited production lines and trims: 4680 cells used in some plants or pilot programs, sometimes associated with newer pack architectures.
- Supplier diversity: While Panasonic is a major source for 2170 NCA cells in many US builds, other suppliers have appeared on specific lines or regions.
Key regional and format variations observed in 2023 models:
These differences mean there isn’t a single, universal battery type for all 2023 Model Y cars; the chemistry and cell format depend on where the car is built and which trim it represents.
Summary
In 2023, the Model Y’s battery typically consists of nickel-rich NCA chemistry in 2170 cells for US-market Long Range and Performance versions, with CATL’s LFP chemistry used in Chinese standard-range models. Some production lines also experimented with 4680 cells in limited builds. The exact battery type varies by region, trim, and time, reflecting Tesla’s evolving supply and manufacturing strategies.
