Tesla’s LFP batteries are primarily manufactured by Chinese companies like CATL and BYD, with production facilities both in China and now emerging in the US. Tesla recently unveiled its LFP battery factory in Nevada, aiming to reduce reliance on Chinese imports, while still leveraging Chinese technology and manufacturing expertise.
Who Are the Main Manufacturers of LFP Batteries for Tesla?
The primary manufacturers supplying Tesla with lithium iron phosphate (LFP) batteries are Contemporary Amperex Technology Co. Limited (CATL) and BYD. These Chinese companies dominate LFP production and supply high-quality battery cells used in Tesla’s economy models and energy storage systems.
CATL notably licensed its manufacturing technology to Tesla, facilitating equipment and process transfer for Tesla’s emerging domestic production.
Where Are Tesla’s LFP Batteries Produced?
Tesla sources most of its LFP battery cells from China, leverages production at its California Megapack factory for energy storage, and has recently opened a dedicated LFP battery cell factory in Nevada. This new US facility is near completion and aims to supply around 10 GWh annually, decreasing Tesla’s dependence on Chinese imports.
The Nevada factory uses manufacturing equipment acquired from CATL, marking a strategic move to onshore production.
Why Is Tesla Shifting LFP Battery Production to the US?
Tesla’s shift to US production helps reduce the impact of tariffs on Chinese imports, secures supply chain resilience amid geopolitical tensions, and taps into domestic incentives. Producing LFP batteries in the US also gives Tesla more control over quality and supply to support its growing energy storage and vehicle manufacturing needs.

How Do Manufacturing Technologies for LFP Batteries Differ?
Tesla’s Nevada LFP plant employs a wet coating process acquired from CATL, differing from dry electrode manufacturing used elsewhere. This technology balances cost-effectiveness and quality. Recent innovations include Tesla’s development of boosted LFP cathode materials with nickel additions for improved performance and longevity.
When Did Tesla Begin Building Its Own LFP Production Facility?
Tesla planned an LFP battery factory in the US as early as 2022, acquiring CATL equipment to accelerate domestic production. The Nevada LFP plant unveiled in mid-2025 is nearing operational status, focusing initially on producing LFP cells for energy storage products like Megapacks.
Which Tesla Models Use LFP Batteries?
Tesla uses LFP batteries primarily in its Standard Range models such as Model 3 and Model Y. Additionally, LFP cells power Tesla’s energy storage products, including Powerwalls and Megapacks, due to their affordability, safety, and long cycle life compared to nickel-based alternatives.
How Does Redway Battery Relate to Tesla’s LFP Battery Strategy?
Though Redway Battery is not a direct supplier to Tesla, its expertise in OEM lithium iron phosphate battery manufacturing parallels Tesla’s LFP strategy. Redway’s high-performance, customized LiFePO4 solutions reflect industry trends emphasizing safety, durability, and adaptability in electric vehicle and energy storage applications worldwide.
Can Tesla’s LFP Batteries Match Performance of Nickel-Based Cells?
While LFP batteries traditionally have lower energy density than nickel-manganese-cobalt (NMC) cells, Tesla’s recent advances—including incorporating small amounts of nickel via patented cathode blends—show promise in narrowing this gap. LFP offers advantages in safety, cost, and longevity that complement Tesla’s vehicle and storage ecosystem.
Are There Global Trends Accelerating LFP Battery Production?
Yes, global trends show increased LFP adoption for electric vehicles and stationary energy storage. China leads production, but US and Korean companies (such as LG Energy Solution) are expanding LFP capacity. Tesla’s investments exemplify this shift as manufacturers balance cost reduction and sustainability concerns.
Table: Key LFP Manufacturers for Tesla and Production Locations
| Manufacturer | Location(s) | Role |
|---|---|---|
| CATL | China, equipment supplied to US | Primary LFP cell supplier |
| BYD | China | LFP cell supplier |
| Tesla | Nevada (US), California (US) | LFP battery cell manufacturer |
| LG Energy Solution | Planned US factory | Upcoming LFP supplier (rumored) |
