摘要
介绍了一种超级电容器负极材料.采用简便的一步水热法成功合成了一种多金属氧酸盐配位聚合物(POMCP1),并通过三电极系统测试其超级电容器性能.在电流密度为 8 A·g-1 时,比电容达到了186.3 F·g-1;在电流密度为30 A·g-1时,其比电容仍然维持在123.9 F·g-1.并将POMCP1 与具有优异导电性的 MXene 材料 Ti3C2Tx 结合,由此产生的杂化材料称为POMCP1@Ti3C2Tx.POMCP1@Ti3C2Tx表现出优异的比电容,在电流密度为 8 A·g-1 时,比电容为521.7 F·g-1;在电流密度为30 A·g-1时,其比电容仍然维持在 402.8 F·g-1,表现出优秀的倍率性能,超过了该类别中许多其他材料,为开发基于多酸基配位聚合物作为超级电容的杂化电极材料提供了一种有效的途径.
Abstract
A kind of supercapacitor anode material is introduced.A Polyoxometalate-based coordination polymers(POMCP1)was successfully synthesized by a simple one-step hydrothermal method,and its supercapacitor performance was tested by a three-electrode system.When the current density is 8 A·g-1,the specific capacitance reaches 186.3 F·g-1.When the current density is 30 A·g-1,the specific capacitance remains at 123.9 F·g-1.Combining POMCP1 with Ti3C2Tx,an MXene material with excellent electrical conductivity,the resulting hybrid material,called POMCP1@Ti3C2Tx.POMCP1@Ti3C2Tx,exhibits excellent specific capacitance.When the current density is 8 A·g-1,the specific capacitance reaches 521.7 F·g-1.When the current density is 30 A·g-1,the specific capacitance is still maintained at 402.8 F·g-1,showing excellent rate performance,which exceeds many other materials,provides an effective way to develop hybrid electrode materials based on polyacid-based coordination polymers as supercapacitors.
