负极材料为Li4Ti5O12的18650型锂离子电池的性能
The performance of 18650 type Li-ion battery with Li4Ti5O12 as anode material
摘要
Abstract
The charge-discharge performance of 18650 type Li-ion battery using Li4 Ti5 O12 as anode material was studied. The investigetion of 2025 type Li4 Ti5 O12- Li simulated cell showed when cycled at 0.1 C in 1.00 ～ 2.00 V, the initial specific discharge capacity and the charge-discharge efficiency of Li4 Ti5 O12 were 150 mAh/g and 95％ ,respectively. The 0.2 C charge plateau of 18650 type LiFePO4- Li4 Ti5 O12 battery mainly stabilized at 1.9 V, while the discharge plateau was about 1.8 V,the charge-discharge platform was very stable. The cbarge-discbarge plateau of LiCoO2- Li4Ti5O12 and LiMn2O4- Li4Ti5O12 batteries mainly stabilized at 2.2 ～ 2.5 V. The voltage change at the end of ebarge of battery using Li4Ti5O12 as anode material was more significant compared with the battery using graphite as anode material.关键词
