What is LiFePO4 / LFP battery? 2023-07-14 14:02:03.082

LFP stands for Lithium Iron Phosphate. Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as the positive electrode material. It is characterized by not containing valuable elements such as cobalt. Phosphorus and iron are abundant in the resources of the earth, and the price of raw materials is low. Lithium iron phosphate batteries have moderate working voltage, large capacity per unit weight, high discharge power, fast charging and long cycle life, wide working temperature range, and high stability in high temperature and high heat environments.

What is the difference between lead-acid batteries and lithium iron phosphate (LFP) batteries? 2023-07-14 14:02:32.154

The two batteries have the following differences: 1. Weight to volume ratio. Lithium iron phosphate batteries are much lighter and smaller than lead-acid batteries, about 1/3 of lead-acid batteries. 2. The power of the battery, the single lithium phosphate battery is about 4 times that of the lead-acid battery. 3. In terms of environmental protection, a large amount of heavy metal lead is used as a raw material in the production process of lead-acid batteries, which has great pollution to the environment, while phospholithium-acid batteries do not contain any heavy metals. 4. Different energy density, lead-acid battery 40Wh/kg, lithium battery 150Wh/kg; 5. Safety, the safety of lithium-ion battery materials is different, and the safety of lead-acid batteries is higher than that of lithium-ion batteries. 6. The cost of energy storage used in the full cycle, due to the short life of the lead-acid battery, compared with the full cycle, the cost of the lithium-ion battery is lower.

Are battery storage systems recyclable? 2023-07-14 14:02:52.556

The disposal and recycling of batteries continues to place a heavy burden on the environment. Some lead-acid batteries can be safely recycled to recover lead and other materials, but many lead-acid batteries still end up in landfills, especially in developing countries. Our energy storage systems use only lithium iron phosphate (LFP). Because the electrodes in LFP batteries are made from non-toxic materials, they are much less of a threat to the environment than lead-acid batteries. They also recycle materials for electrodes, wires and housings. Some of these materials could be used in new lithium batteries. LiFePO4 batteries containing recycled materials are already available. Due to the long lifespan of LFP batteries and the large number of batteries still in use, the recycling process is clearly still in its infancy. As more lithium batteries reach the end of their useful lives, recycling will naturally become more efficient and less costly as engineers continue to improve the process of recycling the material.
