The electrode prepared with polyvinylidene fluoride binder and N-methylpyrrolidone solvent has an excellent continuous capacity of 381mah·g-1 under 15ag-1. In contrast, lithium polyacrylate and deionized water electrodes provide a reversible capacity of 950 mAh g-1 under the condition of 0.5 ag-1 after 100 cycles. These interesting results are attributed to the internal characteristic structure of these two electrodes, which has been confirmed by electrochemical kinetics and scanning electron microscope images. The results also show that different dispersion states are the main reason for the difference in electrochemical performance of lithium-ion batteries, which highlights the importance of high-performance lithium-ion battery electrode design
