What is the material of Tesla batteries?
2 Answers
Tesla batteries are lithium-ion batteries with nickel-cobalt-manganese oxide or nickel-cobalt-aluminum oxide ternary cathode materials. Taking the 2021 Rear-Wheel Drive Upgraded Tesla as an example, its body dimensions are: 4694mm in length, 1850mm in width, and 1443mm in height, with a wheelbase of 2875mm and a trunk capacity of 425 liters. The 2021 Rear-Wheel Drive Upgraded Tesla features a double-wishbone independent front suspension and a multi-link independent rear suspension. It is equipped with a permanent magnet synchronous motor, delivering a maximum power of 202 kW and a maximum torque of 404 Nm, paired with a fixed gear ratio transmission.
Tesla batteries are primarily lithium-ion batteries, composed of cathode, anode, electrolyte, and casing. The cathode commonly uses nickel-cobalt-aluminum (e.g., Model S) or lithium iron phosphate (base Model 3), offering high energy density but with environmental concerns over cobalt and nickel mining. The anode is typically graphite, responsible for storing lithium ions. The electrolyte is a liquid or solid mixture ensuring ion flow, while the casing protects internal components. These material designs enable long range and fast charging—for instance, when driving a Tesla, I experience smooth acceleration and sufficient daily commute range, though winter range slightly decreases due to reduced lithium-ion activity in cold temperatures. Aligning with eco-trends, Tesla is promoting lithium iron phosphate batteries to reduce reliance on rare metals and advancing recycling programs, allowing partial resource reuse when returning old batteries—a more sustainable approach. Overall, material choices directly impact safety and lifespan. I recommend regular battery health checks and avoiding deep discharges to prolong battery longevity.
