NaCa₂Si₃O₈(OH) nanowires with diameters of 100–150 nm and lengths up to several tens of micrometers have been successfully prepared on a large scale via a one-step hydrothermal methode. The poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS)-coated NaCa₂Si₃O₈(OH) nanowires have also been prepared via a simple dip-and-dry technique. The electrochemical performances of the NaCa₂Si₃O₈(OH) and NaCa₂Si₃O₈(OH)/PEDOT:PSS nanowires were investigated. Compared with pure NaCa₂Si₃O₈(OH) nanowires, the NaCa₂Si₃O₈(OH)/PEDOT:PSS composite nanowires exhibit improved electrochemical properties of higher discharge/charge capacity and better cycling reversibility. This is the first time that NaCa₂Si₃O₈(OH) nanostructures were used as anode materials in lithium-ion batteries, and the present work will greatly expand the application fields of NaCa₂Si₃O₈(OH).

通过一步水热法成功地大规模制备了直径为100-150 nm，长度可达几十微米的NaCa ₂ Si ₃ O ₈（OH）纳米线。聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）包覆的NaCa ₂ Si ₃ O ₈（OH）纳米线也已通过简单的浸没-干燥技术制备。研究了NaCa ₂ Si ₃ O ₈（OH）和NaCa ₂ Si ₃ O ₈（OH）/ PEDOT：PSS纳米线的电化学性能。与纯NaCa ₂ Si ₃相比O ₈（OH）纳米线，NaCa ₂ Si ₃ O ₈（OH）/ PEDOT：PSS复合纳米线表现出改善的电化学性能，具有更高的放电/充电容量和更好的循环可逆性。这是首次将NaCa ₂ Si ₃ O ₈（OH）纳米结构用作锂离子电池的负极材料，目前的工作将大大扩展NaCa ₂ Si ₃ O ₈（OH）的应用领域。
