223. Uniform Al Doping in LiCoO2for 4.55 V Lithium-Ion Pouch Cells

Author

Abstract

As the classic cathode material, lithium cobalt oxide (LiCoO2, LCO) suffers from severe structural and interfacial degradation at voltage >4.5 V, which induces fast capacity decay of the cells. Herein, we adopt a simple and effective method, doping aluminum (Al) cations in precursors, to improve the structural stability of LCO and systematically investigate the effect of Al doping on the electrochemical performances. Doping in precursors rather than bulk particles is beneficial to realize uniform Al ions distribution. Even at 4.5 V charging voltage, the LCO/graphite pouch cells with high Al doping levels (8500 ppm) deliver initial and reversible discharge capacities of 386 and 369 mAh after 500 cycles, respectively. The capacity retention is as high as 95.5%. When the cutoff voltage reaches 4.55 V, the pouch cell maintains 79.0% of the first-cycle discharge capacity after 500 cycles. With optimized electrolyte, the pouch cell realizes 87.3% of the initial discharge capacity after 500 cycles at 45 °C. Moreover, the thermal safety performance of the pouch cells with Al doping is promising. Our work displays an excellent inspiration for developing high-voltage, long-cycle, and safe LCO cathode for commercial lithium-ion batteries.

Abstract

To better understand why Chinese residents' COVID-19 perceptions of the importance of vaccination change dramatically over time, this research used an online lab-like experiment to test the antecedents of individuals' perception of the importance of COVID-19 vaccines. We find that participants who view themselves as separate from others (i.e. independent self-construal) perceive COVID-19 vaccines as more important than Hepatitis B vaccines (i.e. control group), regardless of how salient mortality is for them. In contrast, among participants who view themselves as a part of their social groups (i.e. interdependent self-construal), awareness of death (i.e. mortality salience) plays a moderating role. Specifically, when mortality is salient, COVID-19 vaccines are considered more important than Hepatitis B vaccines; when morality is not salient, vaccine type does not make a difference on perceptions of vaccine importance.
