Teslo, the renowned electric vehicle manufacturer, has been making headlines for its adoption of lithium iron phosphate (LiFePO4) batteries in some of its standard-range vehicles. This shift from traditional lithium-ion batteries to LiFePO4 chemistry marks a significant step in the company’s battery strategy.
Tesla has standardized on cylindrical batteries for its electric vehicles. This approach, compared to other OEMs using diverse battery models from multiple suppliers, offers advantages like improved performance, greater flexibility, and better cost control.
According to the Gaogong Industry Research Institute (GGII), China’s power battery installed capacity in the first half of 2019 involved a staggering 204 different single-cell specifications. Among these, all square batteries were sourced from CATL, primarily for the standard-range versions of Model 3 and Model Y. CATL supplied not only Tesla’s Shanghai factory but also its US facility. Cylindrical batteries, on the other hand, came from Panasonic and LG, powering long-range and high-end models.
Since the introduction of 4680 batteries in 2023, Tesla has reshaped its battery supply chain, reducing reliance on external suppliers, including those from China.
Why is Tesla using LiFePO4 batteries?
Several factors have driven Tesla’s decision to embrace LiFePO4 batteries:
- Kostefikeco:LiFePO4 batteries offer lower production costs compared to traditional lithium-ion batteries containing cobalt and nickel. This cost advantage can translate into more affordable electric vehicles for consumers.
- Sekureco:LiFePO4 batteries are inherently safer than other lithium-ion chemistries due to their stable chemical structure. They are less prone to thermal runaway, a dangerous condition that can lead to battery fires and explosions.
- Longviveco:LiFePO4 batteries generally have a longer lifespan than other lithium-ion batteries, potentially extending the range and service life of Tesla’s electric vehicles.
- Resource Abundance:The materials used in LiFePO4 batteries, iron and phosphate, are more abundant and less susceptible to supply chain disruptions compared to cobalt and nickel used in traditional lithium-ion batteries.
