Which one is better for power lithium battery?

Lithium manganese oxide battery (LiMn2O4) and lithium iron phosphate battery (LiFePO4), which one is better for power lithium battery? Let’s compare their advantages and disadvantages below: 1. Advantages of lithium iron phosphate batteries 1. Improvement of safety performance. The PO bonds in the lithium iron phosphate crystals are stable and difficult to analyze, even at high temperatures or overcharge. Like lithium cobalt oxide, it will collapse and heat up or form strong oxidizing substances, so it has good safety. 2. Improved lifespan Lithium iron phosphate battery refers to a lithium battery that uses lithium iron phosphate as a positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, the highest is 500 times, while the cycle life of lithium iron phosphate power lithium-ion batteries can reach 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, while lithium iron phosphate batteries used under the same conditions, the theoretical life will reach 7 to 8 years. Considering comprehensively, 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. Under the special charger, the battery can be overflowed within 40 minutes of 1.5C charging, and the starting current can reach 2C, but the lead-acid battery does not have this 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℃. The working temperature range is wide (-20C75C), with high temperature resistance, the peak value of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. 4. When large-capacity batteries work under conditions that are often overflowing, the capacity will quickly fall below the rated capacity. 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 at any time without having to discharge it before charging. 6. Light weight, the volume of the lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery. 7. The environmental protection lithium iron phosphate battery is generally considered to be free of any heavy metals and Rare metals (Nickel-metal hydride batteries require rare metals), non-toxic (SGS certification), no pollution, in line with European RoHS regulations, is an absolute green battery certificate. Therefore, the reason why lithium 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. However, some experts said that the environmental pollution caused by lead-acid batteries mainly occurred in the company's irregular processing and recycling processes. In the same way, lithium batteries belong to the new energy industry, but it cannot guard against the problem of heavy metal pollution. Lead, arsenic, cadmium, mercury, and chromium in the production of metal materials may be released into dust and water. The battery itself is a kind of chemical substance, so there may be two kinds of pollution: one is the pollution of process excrement in the processing engineering; the other is the pollution of the battery after it is scrapped. Lithium iron phosphate batteries also have their shortcomings: for example, poor low-temperature performance, low tap density of the positive electrode material, and the volume of lithium iron phosphate batteries of equal capacity is larger than lithium batteries such as lithium cobalt oxide, so they have no advantages in miniature batteries. When used in power lithium-ion batteries, lithium iron phosphate batteries are the same as other batteries, and they have to face battery consistency problems.
