Explain the rate discharge curve index of lithium manganate monomer

The exponential high-rate discharge of lithium manganate monomer multiplier discharge curve is an important goal of power batteries. Through the above experiments, it is found that the lithium manganate series power battery can withstand up to 30A current discharge. The maximum discharge current of a lithium iron phosphate battery is 15A. When high-current discharge, the lithium manganese acid battery can still reach more than 1400mAh, while the lithium iron phosphate battery processed by other companies can reach below 900mAh under 1mAh. 0 current discharge. It is worth noting that the lithium iron phosphate battery has not reached the manufacturer's rated capacity, that is, the actual capacity when discharged at 1C is only about 1000mAh. What does this effect mean? Power tool manufacturers will be very clear. Since the normal working current of professional electric tools is generally 15-20a, if it is blocked, the instantaneous working current can reach 50-60a. ES is far from the foundation of professional power tools. Some people may say that the voltage capacity of a single lithium iron phosphate battery cannot be reached, can it not be connected in series or parallel? This is no problem, but series and parallel greatly increase the application, volume and weight, as well as the use of cost and reverse transmission. It can be seen from the above data that the capacity of MNKE battery is 1.5 times that of other companies' lithium batteries. MNKE batteries may be the first choice for power tool manufacturers. The low temperature of LiFePO4 batteries is a problem. Although there are various methods (such as doping lithium, iron, and even phosphoric acid sites to promote ionic and electronic conductivity during the sintering process), important or minor specifications and descriptions of particles passing through a high-quality powder sintering furnace are useful for improving the operation of the reaction zone , And Nd electronic conductivity by adding additional conductive agent. The low temperature travel function of lithium iron phosphate, but the inherent characteristics of lithium iron phosphate materials, its low temperature function is not as good as lithium manganate cathode materials.
