摘要
随着打印机设备需求的增长,废弃硒鼓的数量也在不断增大,而废弃的硒鼓中仍存在一定的残留墨粉,不合理的丢弃严重危害了环境及人类健康。因此,需要对废弃墨粉进行资源化利用。本研究采用高温加热的方法对废弃墨粉进行处理,制得Fe3O4负极材料,并进行了表征及电化学应用测试。经过恒电流充放电、循环伏安及交流阻抗等电化学性能的测试,结果表明:制得的Fe3O4负极材料在电压区间为0.02~1.5 V,电流密度为40 m A/g的条件下,首次放电比容量高达1 111.01 m Ah/g,50次循环后的比容量能够保持296 m Ah/g,表现出良好的循环稳定性。
As the increase of the printing equipments,the number of abandoned toner cartridges goes up fast. There are still some residual toners stored in abandoned toner cartridges; unreasonable discarding is serious damage to the environment and human health. Thus,it is necessary to recycle waste toner. This research adopt the method of high temperature heating to deal with waste toner,in order to make the Fe3O4 anode material,and the characterization and electrochemical application tests on the product was carried out. After the electrochemical performance test of constant current charge and discharge,cyclic voltammetric and AC impedance,the results showed that the anode materials of Fe3O4 under current density of 40 m A / g,in voltage range of 0. 02 ~ 1. 5 V,discharge specific capacity was up to 1 111. 01 m Ah / g for the first time,the specific capacity of the 50 th cycle could be maintained at 296 m Ah / g,which showed a good cycling stability.
