研究了由1，4，5，8-naphthalenetetracarboxylic-dianhydride和苯二胺合成的聚酰亚胺-多壁碳纳米管复合材料(PNP@CNT)作为水基钠离子电池负极材料的性能。该复合材料在-0.65V(vs.SCE)的低电位下表现出149 mA h g(-1)的高可逆容量、优异的倍率能力和长期的循环稳定性。结合Na0.44MnO2正极材料，证实了PNP@CNTs在水基Na离子全电池中应用的可行性，有望作为高性能的水基Na基负极应用于大规模电能储存。
A polyimide-MWCNT composite (PNP@CNT) synthesized from 1,4,5,8-naphthalenetetracarboxylic-dianhydride (NTCDA) and phenylene diamine (PDA) was investigated as a novel anode for aqueous Na-ion batteries. This composite demonstrates a high reversible capacity of 149 mA h g(-1) at quite a low potential of -0.65 V (vs. SCE), superior rate capability and long-term cycling stability. The feasibility of PNP@CNTs in aqueous Na-ion full batteries is also confirmed in conjunction with the Na0.44MnO2 cathode, possibly serving as a high performance aqueous Na host anode for large-scale electric energy storage applications.
