Piezoelectric Composite of BaTiO3-coated SnO2 Microsphere Li-ion Battery Anode with Enhanced Electrochemical Performance Based on Accelerated Li+ Mobility |
| 초록 |
A BaTiO3-coated SnO2 microsphere composite (SnO2@BaTiO3) with high porosity was prepared via a solvothermal process and solution coating for application as an anode for high-performance Li-ion batteries. BaTiO3 in the as-formed SnO2@BaTiO3 composite generated locally polarized piezoelectric fields under the mechanical stress generated by the volume expansion of SnO2 during the redox process. The synergistic effect of the local piezoelectric potential and high porosity of the SnO2@BaTiO3 composite electrode improved its Li+ mobility as compared to that of the SnO2 microsphere. The improved Li+ mobility of the SnO2@BaTiO3 composite enhanced its electrochemical performance as the anode for Li-ion batteries. |
