Abstract
Systems and methods are provided for battery cells including solid electrolytes. Solid electrolyte cells may be integrated with electronic devices. For example, a solid electrolyte cell may be integrated with a metal surface of a circuit board or an electrically conductive surface of a chassis. Surface-mountable solid electrolyte cells may be electrically coupled to circuit traces using, for example, a reflow soldering process.
