英文摘要 | underutilization due to performance limitations imposed by species and charge transports is one of the key issues that persist with various lithium-ion batteries. to elucidate the relevant mechanisms, two groups of characteristic parameters were proposed. the first group contains three characteristic time parameters, namely: (1) t(e), which characterizes the li-ion transport rate in the electrolyte phase, (2) t(s), characterizing the lithium diffusion rate in the solid active materials, and (3) t(c), describing the local li-ion depletion rate in electrolyte phase at the electrolyte/electrode interface due to electrochemical reactions. the second group contains two electric resistance parameters: r-e and r-s, which represent respectively, the equivalent ionic transport resistance and the effective electronic transport resistance in the electrode. electrochemical modeling and simulations to the discharge process of licoo2 cells reveal that: (1) if te, ts and tc are on the same order of magnitude, the species transports may not cause any performance limitations to the battery; (2) the underlying mechanisms of performance limitations due to thick electrode, high-rate operation, and large-sized active material particles as well as effects of charge transports are revealed. the findings may be used as quantitative guidelines in the development and design of more advanced li-ion batteries. |
