Cymbet Corp. (Elk River, MN) announced its application-specific, solid energy technology (ASSET®), thin-film, rechargeable batteries that can be customized in physical size and energy capacity to fit on or within integrated circuit packages with little or no impact to the IC package profile. The battery can be custom made to fit virtually any physical size required by the circuit or system design, eliminating the need for bulky battery compartments.
The battery can be a stand-alone power source on a flexible or rigid substrate, or fabricated on the circuit or device that it is intended to power, such as on the lid of an integrated circuit, or on the surface of a printed circuit board. The batteries are designed to satisfy applications such as non-volatile SRAMs, real-time clocks and supply supervisors, and active RFID tags. The nominal cell voltage is 3.8V, and the total cell thickness can be as thin as 25 microns (1 mil). The cells are capable of greater than 10,000 deep-charge and discharge cycles and operate over a temperature range of -40 to +120 degrees C. The solid-state battery is able to withstand solder-reflow temperatures and can be surface-mounted along with other electronic components on high-volume manufacturing lines.
