The aim of this work is identification of the structural components of actual domestic spent alkaline AA batteries, as well as quantification of some of their characteristics. Weight, humidity, ash content, zinc and zinc oxide on anode, manganese on cathode and other metals, potassium hydroxide on the internal components and heating values for papers, anode and cathode were determined in several batteries. As expected, cathode, anode and the steel can container are the main contributors to the 23.5 g average weight of the batteries. Cathode is also the major contributor to the positive heating value of the batteries as well as to the heavy metals content. Mercury was detected in very low levels in these mercury-free batteries. Zinc and zinc oxide amounts in the anodes are highly variable. Results obtained were compared to information on alkaline batteries in the literature from 1993 to 1995; and a positive evolution in their manufacture is readily apparent. Data from the producer of batteries shows some small discrepancies relative to the results of this experimental work.
这项工作的目的是识别实际家用废旧碱性AA电池的结构成分，并对其一些特性进行量化。测定了多个电池的重量、湿度、灰分含量、阳极上的锌和氧化锌、阴极上的锰和其他金属、内部组件上的氢氧化钾以及纸张、阳极和阴极的热值。正如预期的那样，阴极、阳极和钢制容器是电池平均重量23.5克的主要贡献者。阴极也是电池正热值以及重金属含量的主要贡献者。在这些无汞电池中检测到的汞含量极低。阳极中的锌和氧化锌含量变化很大。将所得结果与1993年至1995年文献中关于碱性电池的信息进行了比较；其制造过程中的积极进展显而易见。电池生产商提供的数据与本实验工作的结果存在一些小差异。
