It has the advantages of low cost, high safety performance, high thermal stability, no spontaneous combustion due to acupuncture and overload, long lifespan, safety and explosion risk.
The theoretical capacity of lithium iron manganese phosphate is the same as that of lithium iron phosphate, which is 170 mAh/g, but the electrode potential of lithium iron manganese phosphate to Li/Li is 4.1V, which is much higher than that of iron phosphate. The 3.4V of lithium, which is located in the stable electrochemical window of the organic electrolytic system, is 0.7V higher than that of lithium iron phosphate, and the platform voltage is increased by 20%. , thus promoting the energy density of lithium iron manganese phosphate under the same volume and mass of 578 Wh/kg increased to 697 Wh/kg.
The princeThe main difference between the dosage of lithium iron manganese phosphate and lithium iron phosphate is the change in the amount of manganese source required. Each kWh of lithium iron phosphate cathode requires 0.61 kg of iron source, while each kWh of lithium iron phosphate cathode requires 0.61 kg of iron source. The kWh of lithium iron manganese phosphate requires 0.61 kg of iron source. The positive electrode requires 0.13 kg of iron source + 0.38 kg of manganese source.
