Thin-Film Batteries for Embedded Systems
Cymbet Corporation announced its EnerChip family of solid-state, thin-film batteries. The products provide energy storage in form factors such as coin cell batteries and super capacitors. The battery is available in capacities of 12µ Ah, 50µ Ah and 85u Ah and can be automatically surface mounted. The devices can be lead-free reflow soldered (260°C) using high-speed SMT pick & place assembly processes. The devices offer a fast recharge time (under 30 minutes to 80 percent), are capable of greater than 5,000 charge/discharge cycles and do not suffer from the self-discharge limitations associated with super capacitors or shelf-life limitations common to chemical batteries. The family is suitable for applications where back-up power is needed to maintain the settings of microcontroller memories, real-time-clocks and SRAM during power loss or power failures. When coupled with energy-harvesting or energy-scavenging techniques, the battery can supply the energy storage to build self-contained, long-lived powered systems.
