| description |
NASICON type solid electrolyte LiZr2 (PO4 )3 has excellent structural stability and performance reliability, but its low conductivity of lithium ions at room temperature limits the transport of lithium ions. In view of the above problems, cationic doping of LiZr2 (PO4 )3 electrolyte material was studied by sol-gel method and thus improve the transport capacity of lithium ions in the material. Meanwhile , modified the electrode with doped LiZr2 (PO4 )3 electrolyte to improve the lithium ion transport performance of the electrode itself. The influence mechanism of ion-doped electrolyte on lithium ion diffusion kinetics of electrode was investigated. The experimental results show that LiTi0. 25 Zr1. 75 (PO4 )3 improves the lithium ion diffusion kinetics most significantly, and the lithium ion diffusion coefficient reaches 3. 25 × 10 - 14 cm2 ·S - 1 , which is 2. 95 times of that of the unmodified electrode. At 5C rate, the specific capacity of LiTi0. 25 Zr1. 75 (PO4 )3 modified electrode is 25. 48 mAh g - 1 higher than that of the unmodified electrode. |
