Highly flexible, binder-free cathodes for lithium ion batteries were fabricated by utilizing N doped carbon to coat VO (VO@N-C) nanobelt arrays growing on carbon cloth. Such a robust architecture endows the electrode with effective ion diffusion and charge transport, resulting in high rate capability (135 mA h g at 10C) and excellent cycling performance (215 mA h g after 50 cycles at 0.5C).
通过利用氮掺杂碳包覆生长在碳布上的VO（VO@N-C）纳米带阵列，制备了用于锂离子电池的高柔韧性、无粘结剂阴极。这种坚固的结构赋予电极有效的离子扩散和电荷传输能力，从而实现高倍率性能（在10C时为135 mA h g）和出色的循环性能（在0.5C下50次循环后为215 mA h g）。
