What kind of batteries do Tesla electric vehicles use?

[McRobert]

Tesla uses ternary lithium batteries. The models under Tesla include: 1. Model Y; 2. Model 3; 3. Model X; 4. Model S; 5. Cybertruck; 6. Roadster. Here are some relevant details: 1. Taking the 2021 Model Y as an example, its body dimensions are: 4750mm in length, 1921mm in width, and 1624mm in height, with a wheelbase of 2890mm and a body weight of 1997kg. 2. The 2021 Model Y features a front suspension in the form of a double-wishbone independent suspension and a rear suspension in the form of a multi-link independent suspension. It is equipped with a front induction asynchronous motor and a rear permanent magnet synchronous motor. The front motor has a maximum power of 137kW and a maximum torque of 219Nm, while the rear motor has a maximum power of 180kW and a maximum torque of 326Nm. It is paired with a 1-speed fixed gear ratio transmission.

As a deep user of electric vehicles, I have long been following Tesla's battery technology. They primarily use lithium-ion batteries, but the models are constantly being upgraded: the older Model S/X used 18650 cylindrical batteries, which are essentially enlarged versions of ordinary AA batteries; later, the Model 3/Y switched to larger 21700 batteries, directly improving range; the latest 4680 batteries are even larger and more efficient, used in the Cybertruck. Battery suppliers include Panasonic, CATL, LG, among others, with entry-level models often using lithium iron phosphate (LFP) batteries, which are cheaper and safer. Tesla also develops its own battery technologies, such as dry electrode processes that enhance efficiency. These batteries are like the heart of an electric car—technological iterations directly impact range and performance, and it's common for newer models to run hundreds of kilometers more than older ones.

Both of our family's Teslas use ternary lithium batteries, which have high energy density. For example, the Long Range Model Y can travel 500 kilometers on a full charge, making it perfect for daily commutes with only one charge needed per week. These batteries are sensitive to extreme heat and cold. Parking in the shade during summer helps prolong battery life, while winter conditions can significantly reduce range. For maintenance, it's recommended not to always charge to full capacity; setting the limit to 90% is better for the battery's longevity. Tesla offers an 8-year battery warranty, and our older car, after 6 years of use, shows less than 10% battery degradation, proving its durability. The recently introduced 4680 battery is said to charge faster and last longer, making it a key feature we'll focus on when considering our next vehicle upgrade.

I have researched the material structure of Tesla batteries. The core is lithium-ion batteries, which are divided into two types: ternary lithium and lithium iron phosphate. Ternary lithium uses nickel-cobalt-manganese materials, with high energy density suitable for high-performance vehicles; lithium iron phosphate offers better safety and lower cost, commonly used in entry-level models. Battery cells form the battery pack, managed by the BMS system to regulate temperature and charging/discharging. Effective thermal management can significantly reduce the risk of spontaneous combustion. Additionally, the 4680 battery adopts a tabless design, with lower resistance enabling fast charging. Battery lifespan depends on cycle counts, retaining about 80% capacity after approximately 1500 cycles, making it suitable for daily use for up to ten years.

From an industry perspective, Tesla's battery strategy is quite smart. Initially, they used readily available 18650 batteries to achieve rapid mass production, then customized 21700 cells to enhance competitiveness. Now, they're building their own battery factories to produce 4680 cells, reducing reliance on Panasonic. They also employ different supplier strategies: using Panasonic's ternary lithium batteries for high-performance vehicles and CATL's lithium iron phosphate batteries for affordable models. This combination effectively controls costs while ensuring performance. Even more impressive is their battery recycling program, where 90% of materials from old batteries can be reused after disassembly. This closed-loop model is transforming the entire electric vehicle supply chain.

When buying a car, I carefully compared the characteristics of Tesla batteries. The entry-level Model 3 uses LFP (lithium iron phosphate) batteries, which are low-cost and long-lasting but suffer from reduced range in winter. The high-end versions use NCM (nickel-cobalt-manganese) batteries, offering higher energy density and faster acceleration but at a higher price. The 4680 battery is the future trend, with a 16% increase in range and a 14% reduction in cost, though it's currently only installed in a limited number of models. My advice is to consider your driving scenario: choose NCM for cold northern regions and LFP for more cost-effective options in the south. The official warranty of 8 years or 160,000 km is quite reassuring, and the battery replacement cost is around 40,000 yuan, which is actually lower than the maintenance costs of gasoline cars.
