Tesla has long been known for its cutting-edge designs and sleek electric vehicles (EVs). However, its most powerful innovation isn’t always visible on the road—it’s happening behind the scenes, with Tesla’s battery production efforts on a scale the world has never seen before. Right now, with every passing second, Tesla is producing 536 battery cells. But here’s the kicker:
This impressive feat isn’t happening in just one location. It’s a global operation powered by Tesla’s Gigafactories in Nevada, Texas, Berlin, and Shanghai. This massive effort is making Tesla a leader in energy storage, and today, we’re diving into how Tesla’s battery production is scaling at such unprecedented rates, the technology behind it, and what groundbreaking advancements we can expect in the 2025 Tesla lineup.
How Is Tesla Producing 536 Batteries Every Second?
Tesla’s battery production scale is a game changer for the EV industry. Currently, Tesla is manufacturing exactly 536 battery cells per second—an achievement made possible by innovations in battery technology and production processes. Let’s take a look at how Tesla has gone from producing the original 18650 cells used in the Model S and Model X to now manufacturing the more efficient 2170 cells and the revolutionary 4680 battery that is poised to change the EV market.
The Evolution of Tesla’s Battery Technology
Tesla’s battery technology has evolved significantly over the years, improving in energy density, reducing costs, and becoming more efficient. In 2017, Tesla introduced the 2170 cells used in the Model 3 and Model Y. These cells not only improved energy density, but they also reduced production costs—key factors in making electric cars more affordable.
In 2020, during its Battery Day event, Tesla introduced the 4680 battery—a cutting-edge cell with a tabless design that lowers resistance, boosts efficiency, and cuts production costs. This breakthrough technology was expected to be the key to Tesla’s long-awaited $25,000 EV. However, scaling production of the 4680 battery proved to be challenging, especially with dry electrode manufacturing. Despite these hurdles, the 4680 battery remains one of Tesla’s most exciting innovations.
The Hidden Tech Behind Tesla’s 2025 Battery Breakthrough
While the 4680 battery cells are a huge step forward, Tesla continues to innovate and invest in new technologies to make EVs more affordable, efficient, and sustainable. One of the most exciting areas of innovation involves Lithium Iron Phosphate (LFP) batteries. These batteries are becoming an increasingly important part of Tesla’s strategy due to their lower production costs and longer lifespan compared to other types of batteries.
The Shift Toward LFP Batteries
Tesla’s adoption of LFP technology is a key focus for the company, especially for their more affordable EV models like the Model 3 and Model Y. Unlike Nickel Manganese Cobalt (NMC) batteries, which are more expensive and have a lower lifespan, LFP batteries have emerged as a cheaper and longer-lasting alternative. By 2023, LFP batteries made up around 40% of Tesla’s battery supply for these models in China, and the company is actively testing LFP batteries in the U.S. for their standard versions as well.
Tesla has recognized the potential of LFP cells to drastically reduce production costs, enabling more affordable EVs to enter the market. While LFP batteries are less energy-dense than NMC batteries, their longer lifespan and reduced production costs make them an attractive choice for more accessible electric vehicles.
Solid-State Batteries: The Next Frontier?
Tesla is also closely monitoring advancements in solid-state batteries, which promise to offer higher energy density, faster charging speeds, and improved safety compared to traditional lithium-ion batteries. While still in the research and development phase, solid-state batteries are considered a potential game-changer in the EV space and could significantly impact the future of energy storage solutions.
The Role of Raw Materials in Tesla’s Battery Revolution
Tesla’s massive leap in battery production wouldn’t be possible without securing a stable supply of raw materials. The company’s batteries depend on key materials such as lithium (for charge carriers), nickel (for enhanced energy density), cobalt (to stabilize the cathode), and graphite (for the anode). Securing a reliable supply of these materials is a significant challenge, and Tesla is tackling it head-on with its unique approach.
Vertical Integration: Tesla’s Lithium Refining Plant
While most automakers rely on external suppliers for raw materials, Tesla is vertically integrating its supply chain by building its own lithium refinery in Texas. Tesla’s refining plant in Robstown, Texas is already making significant progress. The plant aims to produce 50 gigawatt-hours (GWh) of lithium annually, providing a steady and self-sufficient supply of raw materials for Tesla’s battery production. This vertical integration strategy ensures that Tesla is not at the mercy of external suppliers, which can be unreliable and subject to price fluctuations.
Dry Electrode Technology: Minimizing Processing Steps
Tesla is also advancing its dry electrode technology, which reduces the number of processing steps involved in manufacturing batteries. This not only helps cut costs but also promotes sustainability by reducing waste and improving the efficiency of battery production. Dry electrode technology is expected to play a significant role in Tesla’s long-term goal of mass-producing its 4680 cells.
How Many Batteries Does Tesla Need for 2024?
With over 1.78 million vehicles projected to be sold in 2024, Tesla will need an astonishing 7 billion battery cells to meet its demand. The breakdown of battery cells needed for different models includes:
- 2,976 cells per Model 3/Y Standard Range
- 4,416 cells per Model 3/Y Long Range
- 7,180 cells per Model S/X
- 1,344 cells per Cybertruck
Beyond its vehicles, Tesla’s energy storage business, including Powerwall and Megapack, is expected to require up to 10 billion cells, surpassing the demand for EV production.
Key Partnerships: Panasonic, BYD, and More
To meet the growing demand for batteries, Tesla has forged key partnerships with several battery manufacturers. Panasonic, for instance, has been a major partner since 2010, supplying 2170 cells for the Model 3 and Model Y. LG Energy Solutions also supplies cells for these models from its factories in Giga Shanghai and Giga Berlin.
Interestingly, one of Tesla’s key battery suppliers is BYD, a company that competes directly with Tesla in the global electric vehicle market. BYD provides LFP cells for Tesla, which are used in the standard versions of the Model 3 and Model Y in China. Despite being competitors in the EV market, BYD and Tesla have come together to push the boundaries of battery technology and help meet the growing demand for EVs.
The Future of Battery Technology: Faster Charging and Longer Battery Life
Looking ahead to 2025, Tesla is focused on three major areas of battery improvement: faster charging speeds, higher energy density, and longer battery life.
