| 제목 | The effect of Y doping on electrochemical behavior of spherical Li4Ti5O12 for Li-ion batteries |
| 초록 | Li4Ti5O12 is emerging as a promising material with its good structure stability and little volume change during the electrochemical reaction. However, its electrochemical performance is significantly limited by low electronic or ionic conductivity. In addition, high tap density is needed forim proving its volumetric energy density and commercialization. To enhance these properties, the spherical-like Li4Ti5O12 particles were synthesized and carried out doping with yttrium. Prepared Y-doped Li4Ti5O12 as a anode material showed great capacity retention rate of 92%(5C/0.2C), compared with no dope done. Consequently, it was found that Y doping into Li4Ti5O12 matrix reduces the polarization and resistance on SEI layer during the electrochemical reaction. |
