The new GeMo complex (namely GeMo) was prepared by mild hydrothermal method and has the molecular formula of C54H36GeMoN6O8. The compound is crystallised in the P-1 space group, with a triclinic symmetry. After two different graphene (namely G) modification methods GeMo-G and GeMo/G are obtained. Among them GeMo-G shows better performance both in lithium ion batteries and supercapacitors. As the electrode material of lithium ion battery, after 100 cycles, the specific capacity of 333.8 mAh g−1 was obtained when the current density was 100 mAg−1. When serving as the electrode material for supercapacitor, the specific capacitance was 1230 F g−1 at a current of 1 A g−1. After 10,000 charge/discharge cycles, 90.8% of the initial specific capacitance has been maintained.

GeMo双金属配合物作为锂离子电池和超级电容器阳极的结构和电化学性能
通过温和的水热法制备了新的GeMo配合物(即GeMo),其分子式为C 54 H 36 GeMoN 6 O 8。该化合物在P-1空间群中结晶,具有三斜对称性。经过两种不同的石墨烯(即G)改性方法,获得了GeMo-G和GeMo / G。其中GeMo-G在锂离子电池和超级电容器中均表现出更好的性能。由于锂离子电池的电极材料,100次循环后的333.8毫安克的比容量- 1是当电流密度为100 MAG获得-1。当用作超级电容器的电极材料时,比电容为1230 F g− 1在1 A g -1的电流下。经过10,000次充电/放电循环后,已保持了90.8%的初始比电容。
