What are the advantages of power lithium-ion batteries

1. Improvement of safety performance. The PO bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and heat up or form strong oxidizing substances in the same structure as lithium cobalt oxide, so it has good safety. Sex. 2. Improved lifespan Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cycle life of a long-life lead-acid battery is about 300 times, and the highest is 500 times. The lithium iron phosphate power lithium battery has a cycle life of more than 2000 times, and the standard charge (5 hour rate) use can reach 2000 times. Lead-acid batteries of the same quality are new for half a year, old for half a year, and for maintenance and maintenance for half a year, at most 1 to 1.5 years, and lithium iron phosphate batteries used under the same conditions, the theoretical life will reach 7 to 8 years. Comprehensive consideration, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries. High-current discharge can quickly charge and discharge high current 2C. With a dedicated charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, but lead-acid batteries have no such performance. 3. Good high-temperature performance. The peak value of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Wide operating temperature range (-20C75C), with high temperature resistance, lithium iron phosphate electric heating peak can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. 4. The capacity of a large-capacity battery will quickly fall below the rated capacity when working under the condition that it is often fully charged and not discharged. This phenomenon is called the memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be charged and used without having to discharge it first. 6. Light weight. The volume of lithium iron phosphate batteries with the same specification and capacity is 2/3 of the volume of lead-acid batteries, and the weight is 1/3 of that of lead-acid batteries. 7. Environmentally friendly power lithium-ion batteries are generally considered to be free of any heavy metals. It is non-toxic (passed by SGS certification), non-polluting, conforms to European RoHS regulations, and is an absolute green battery certificate. Therefore, the reason why lithium-ion batteries are favored by the industry is mainly due to environmental protection considerations. Therefore, the battery has been included in the 863 National High-tech Development Plan during the Tenth Five-Year Plan and has become a key national support and encouragement project. With my country's accession to the WTO, my country's export of electric bicycles will increase rapidly, and electric bicycles entering Europe and the United States have been required to be equipped with pollution-free batteries.
