1/3Co1/3Mn1/3O2、導電添加劑和聚偏氟乙烯制成的電極表面涂覆了一層薄薄的氧化石墨烯。在充電截止電壓為4.3 V的條件下進行了循環(huán)性能和倍率性能測試。結(jié)果表明：未改性電極在恒電流充放電測試中容量下降且極化增加，而包覆改性后電極的容量衰減程度和極化增加速度降低。這是由于氧化石墨烯涂層抑制了LiNi1/3Co1/3Mn1/3O2電極和電解質(zhì)之間的部分副反應，使得改性電極的循環(huán)穩(wěn)定性和倍率性能顯著提高，為提升LiNi1/3Co1/3Mn1/3O2電極性能提供了一種環(huán)境友好且非常有效的方法。;Electrodes consisting of LiNi1/3Co1/3Mn1/3O2, aluminum foil, conductive additives, and polyvinylidene fluoride were coated with a thin graphene oxide layer via a simple screen-printing method. The cycle performance and rate capability were tested at a cut-off voltage of 4.3 V. Results show that the capacity deceases whereas the polarization increases during the galvanostatic charge-discharge tests for primary electrodes. For the graphene-oxide-modified electrodes, the capacity decrement reduces and polarization increment rate evidently slows down. As a result, the cycle stability and rate capability are improved because the graphene oxide coating suppresses the side reactions between the LiNi1/3Co1/3Mn1/3O2 electrodes and electrolyte. The research provides an ecofriendly and highly effective strategy to improve the performance of LiNi1/3Co1/3Mn1/3O2 electrodes."/>
