Investigation of Portable Communication Devices with Electrochemical Power Sources Application Features

In this article we discuss the use of portable subscriber communication devices in which the power is supplied by primary cells and batteries. The article highlights the safety issues of the handheld portable subscriber communication devices which are related to electrochemical power sources using in such devices. The issues of safe electrochemical power sources using in terms of heating temperature during normal operation and in case of malfunctions are considered. The results of the conducted experimental research of manganese-zinc primary cells with salt and alkaline electrolytes and batteries to determine the maximum surface temperature are presented. The absence of significant excess of the primary cell surface temperature, as well as the absence of fires and explosions is revealed. It is concluded that the use of such electrochemical cells is safe. It is proposed to use such electrochemical cells in subscriber portable communication devices.
