dc.description.abstract | Rechargeable batteries with a Li metal anode and Ni-rich Li[NixCoyMn1-x-y]O-2 cathode (Li/Ni-rich NCM battery) have been emerging as promising energy storage devices because of their high-energy density. However, Li/Ni-rich NCM batteries have been plagued by the issue of the thermodynamic instability of the Li metal anode and aggressive surface chemistry of the Ni-rich cathode against electrolyte solution. In this study, a bi-functional additive, adiponitrile (C6H8N2), is proposed which can effectively stabilize both the Li metal anode and Nirich NCM cathode interfaces. In the Li/Ni-rich NCM battery, the addition of 1 wt% adiponitrile in 0.8 M LiTFSI + 0.2 M LiDFOB + 0.05 M LiPF6 dissolved in EMC/FEC = 3:1 electrolyte helps to produce a conductive and robust Li anode/electrolyte interface, while strong coordination between Ni4+ on the delithiated Ni-rich cathode and nitrite group in adiponitrile reduces parasitic reactions between the electrolyte and Ni-rich cathode surface. Therefore, upon using 1 wt% adiponitrile, the Li/full concentration gradient Li[Ni0.73Co0.310Mn0.15Al0.02] O-2 battery achieves an unprecedented cycle retention of 75% over 830 cycles under high-capacity loading of 1.8 mAh cm(-2) and fast charge-discharge time of 2 h. This work marks an important step in the development of highperformance Li/Ni-rich NCM batteries with efficient electrolyte additives. | - |
