Fig. 7 shows two kinds of samples in 0.1Ag-1Cycle performance under charge-discharge magnification.After 75 circulations, MSR- LiEuTiO4Reversible capacity be only 39.2 mAhg-1, capacitance loss 22.0%.In contrast, OSR-LiEuTiO4Even if It is also showed that lower capacity attenuation (10.0%) after 100 circulations, and reversible capacity is 208.7mAhg-1。
Fig. 8 compares two kinds of samples in 0.2-5.0Ag-1Rate capability under charge-discharge magnification.OSR-LiEuTiO4Can Inverse capacity is in 0.2 Ag-1When be 204.3 mAhg-1, in 5.0 Ag-1When be 144.9mAhg-1.Coulombic efficiency is about accordingly 92.7%.And MSR-LiEuTiO4In 0.2 Ag-1In the case of capacity be only 45.9mAhg-1, in 5.0 Ag-1Lower capacity is only 7.2mAhg-1.This significant difference between two kinds of materials, especially at the high velocities, this is attributed to OSR-LiEuTiO4Compared with Small particle and high specific surface area, make Li+With electronics in LiEuTiO4There is faster diffusion rate in body phase.When charge and discharge times Rate becomes 0.1 Ag again-1When, specific capacity is restored to 213.8 mAhg-1.In addition, the OSR-LiEuTiO prepared by us4Charge and discharge times Rate performance is also superior to LiEuTiO reported in the literature4(Chem. Commun. 2017;53:7800-3) (Fig. 9).
The present invention is successfully prepared LiEuTiO using one kettle way4Lithium ion battery anode material.The material has been reported with other The li-ion electrode materials led, which are compared, has better chemical property.The preparation method of the material and the method phase reported in the past Than step simplifies many, and time-consuming is short, advantageously the industrialization of the beneficial material and commercialized development.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
