Seemingly every day, a new type of electronic device enters the market. Increasing numbers of these gadgets are powered by batteries, yet the selection of energy storage devices available to product designers remains limited. As a result, product designers and users alike are often forced to make compromises on how the end product is used. This session focuses on the attributes of, and challenges associated with, modern energy storage devices, with emphasis on small batteries used in portable devices and other space-constrained applications. An overview of key characteristics - including storage capacity, energy density, operating voltage, self-discharge, cycle life, cell resistance, charging parameters, and physical aspects - of commonly used battery chemistries and designs will be presented. Advantages and limitations of several types of energy storage devices will be reviewed, in the context of the demands placed on them by electronic systems incorporating low power sensors, microcontrollers, and radios. A brief treatment will be given to energy harvesting in these applications, along with a glimpse into energy storage devices currently in development and nearing commercial deployment.
