What materials are used in Tesla batteries?
2 Answers
Tesla batteries use cobalt-free NCA ternary lithium batteries. Tesla is an American electric vehicle and energy company founded by Martin Eberhard and Marc Tarpenning in Silicon Valley, California, USA. It primarily produces and sells electric vehicles, solar panels, and energy storage equipment. Tesla's vehicle models include the Model 3, Model Y, Model S, Model X, and the imported Model 3. Taking the Tesla Model S as an example: it is a mid-to-large-sized sedan with a length, width, and height of 4979mm, 1964mm, and 1445mm respectively, and a wheelbase of 2960mm, equipped with a fixed gear ratio transmission.
With years of experience in the auto repair industry, let me discuss Tesla's battery materials. Tesla models primarily use lithium-ion batteries, which are the backbone of modern electric vehicles. The core materials include the cathode, commonly made of nickel-cobalt-aluminum ternary materials, widely used in models like the Model S or X. The anode is graphite-based, paired with a liquid electrolyte such as lithium salts and organic solvents, and the separator is typically a polymer material to prevent short circuits. This combination ensures high energy density and extended range, but it may accelerate aging under high temperatures. It's worth noting that improper daily use or frequent overcharging can lead to cathode material degradation. The battery also features a cooling system to protect its overall structure. In summary, this material selection strikes a balance between performance and cost, and proper maintenance during driving can extend its lifespan.
