[SMM analysis] Lithium-electric two-wheelers enter the peak sales season. The demand for manganic acid in the ternary manganese-doped route continues to increase.

SMM7 March 3, the near future is about to enter the third quarter, and the two-wheeled car market is also about to usher in its traditional sales season, taking into account the possible coming demand, downstream two-wheeled car manufacturers have more stock, directly drive the upstream battery end and material end demand, small power ternary materials, lithium iron phosphate, lithium manganate material demand have varying degrees of volume. Among them, the demand for lithium manganate mixed with ternary materials increases obviously.

It is understood that the mandatory national standard of the 2018 "Safety Technical Specification for Electric bicycles" stipulates that the weight of electric bicycles shall not be greater than 55kg, while the lead-acid battery, which has previously occupied an absolutely dominant position in the two-wheeler battery, has gradually stepped off the altar due to its low energy density, cycle times and more serious pollution problems. According to the data, the current average energy density of lead-acid battery is only 30-50 Whplash kg, and its cycle life is only 300-500 weeks, which is much lower than the performance index of lithium battery with 120-180 Whamp kg and 1500-3000 cycle life. Therefore, in the case of the same mileage, the weight of lead-acid battery is almost several times that of lithium-ion battery, which is difficult to say under the framework of the new national standard. The field of two-wheeled vehicles is also gradually dominated by lead acid and gradually began the process of lithium electrification transformation.

In the current technical route of lithium battery for two-wheeled vehicle, the technical route of ternary manganese doping occupies an important position. It is understood that at present, the demand for the service life of lithium electric two-wheelers in the market is gradually increasing, and the ternary materials with the highest energy density, due to the cobalt and other metals in their material composition, are limited to factors such as uneven distribution and low reserves, so the price is expensive. The product positioning of the electric two-wheeler determines that it has a certain price sensitivity, and there is a demand for cost reduction, so some manufacturers will mix it with the relatively low price of lithium manganate, with a ratio ranging from 7:3 to 5:5, so that the cost can be effectively reduced. At the same time, because the synthesis temperature of lithium manganate is above 700 ℃, which is much higher than the ternary 250 ℃, the ternary material doped with lithium manganate can effectively restrain the thermal runaway problem of the ternary material to a certain extent and improve the thermal stability of the material. the safety performance of the battery is optimized.

With the intensification of competition among lithium-electric two-wheelers, the demand for lithium manganate in the follow-up ternary manganese-doped line is expected to continue to increase because of the continuous cost reduction and safety performance considerations.
