About Cymbet

Cymbet Corporation operates as a key developer of solid-state, thin-film energy storage systems tailored for microelectronic applications. Established in 2000, the company has focused on creating rechargeable, eco-friendly power solutions that can be seamlessly integrated into a variety of electronic devices. Historically, Cymbet has attracted substantial financial backing, securing significant funding from notable corporate investors including Intel Capital, Texas Instruments, and Dow Venture Capital to fuel its product development and market expansion efforts. The company has undergone several funding rounds, including a Series A of $4.5 million, a $16.5 million round in 2007, a $31 million Series C in 2010, and multiple large investments from Island Shore Investments in 2013 and 2016 which also prompted a corporate recapitalization and restructuring.

The core of Cymbet's business is the production and sale of its EnerChip™ solid-state batteries. These are not conventional batteries; they are produced using semiconductor fabrication processes, which allows them to be delivered as either bare die for integration directly into system-in-package (SiP) products or as standard surface-mount technology (SMT) components. This manufacturing approach eliminates liquids and gels, resulting in a safe, non-cytotoxic power source ideal for sensitive applications like medical and healthcare products. Revenue is generated by selling these EnerChip batteries and associated evaluation kits to original equipment manufacturers in sectors such as medical devices, industrial controls, wireless sensors, RFID, and consumer electronics.

Cymbet's primary product, the EnerChip™, is a rechargeable thin-film battery that offers distinct advantages over traditional power sources like coin cells or supercapacitors. Its key features include a miniature footprint, a long operational life with the ability to endure over 5,000 charge-discharge cycles, and compatibility with standard high-volume electronics assembly processes like reflow soldering. Some EnerChip models come with integrated power management circuits, combining the battery and control logic into a single chip, which simplifies design, saves board space, and reduces assembly costs for developers. The technology is particularly well-suited for applications requiring power backup for real-time clocks and SRAM, as well as for energy harvesting systems where the battery can be recharged using ambient energy sources like light or motion.
