BYD lithium iron phosphate battery: the future of environmentally friendly new energyNowadays, lead-acid batteries have been criticized for their low energy density, short cycle life and lead pollution to the environment. Despite the rapid development of China's new energy vehicle industry chain and the emergence of lithium-ion batteries as the mainstream power source, it is surprising that most of the common "12V small batteries" in our daily use of new energy vehicles still use traditional lead-acid batteries. With the improvement of the intelligence of automobiles, the overall power consumption of new energy has increased, and lead-acid batteries appear to be "inadequate".
However, after more than 10 years of development, BYD has successfully launched lithium iron phosphate batteries, realizing lead-free vehicles and solving various problems of lead-acid batteries. BYD launched the first lithium iron phosphate power battery as early as 2005, and three years later it was first equipped with the battery on the F3DM new energy vehicle. In 2020, BYD launched a blade battery that is the culmination of lithium iron phosphate batteries, with an energy density of 180Wh kg, which is comparable to ternary batteries.
Compared with traditional lead-acid batteries, lithium iron phosphate batteries do not contain any heavy metals and rare metals, and are easy to use, reducing the difficulty and cost of waste disposal. In addition, the cycle life of lithium iron phosphate batteries can reach more than 2000 times, or even more than 3500 times, far exceeding the life of lead-acid batteries. Its capacity attenuation rate is low, the safety is high, it does not contain toxic substances, and it is equipped with multiple protections, which greatly reduces the potential safety hazards.
Although lithium iron phosphate batteries have poor endurance at low temperatures, they can still provide reliable performance throughout their service life. To sum up, BYD's lithium iron phosphate battery has shown incomparable advantages and made a significant contribution to environmental protection. It is hoped that more companies will follow BYD's example and contribute to creating a better future.
