一次电池检测

应用加热蒸发高纯锌粉气相传输法,制备锌多面体微球. 产物的结构和形貌经XRD、SEM等测试表征,结果表明与该产物为结晶度较好的直径2～3μm的多面体微球.

A dry cell battery is an electrochemical cell in which the electron transfer of a chemical reaction is conducted outside the battery through an external circuit in a load. The reactions in the battery result in a decrease in the energy content of the substances in the battery, It is this energy decrease which can be used to power a device such as a ?ashlight. It is however not possible to utilize the entire energy because of internal energy losses within the battery. The energy that cannot be used outside the battery is converted to heat within the battery. By measuring this heat the efficiency of the battery may be investigated.
