本文提出一种适于高速充电的新型化学电源电极，该电极体系在充电时，反应界面能迅速推移，使活性物质能迅速沉积在三维载体电极上，特别适用于强电流高速充电．充电时活性物质以固态沉积在电极表面，而放电时活性物质又溶解为液态．电极体系在充放电循环过程中活性物质是以固（ 态）＿液（ 态） 循环形式进行循环，因而可以保持新鲜的电极表面，防止固体电极表面活性物质的相变、钝化、脱落、变形等弊端，有利于延长电极的寿命．该电极体系可望在大电流快速充电的动力电源上获得应用

In most of practical rechargeable batteries, charging/discharging process is always concerned with phase_transformation in the solid state. Due to the irreversibility of the phase_transformation, the cyclic performance of the rechargeable batteries are limited. In this paper, a novel reaction_region moving counter electrode system is constructed in our laboratory. The electrode system is operated at room temperature and cycled in solid_liquid phase during charging/discharging processes. With this electrode, the metal_complexes are firstly deposited(i.e. charging process) on the nearest working electrode and gradually extended to those another working electrodes several centimeters away from the counter electrode. The deposite is dissolved again into the solution during discharge process. Owing to the movement of the reaction_region, the electrode system can be used to produce high surface area electrodes and it can also be charged at high current, which has been used to design high energy_density rechargeable batteries in our group.
