Anode-less Solid-State Lithium Chemistry Enables Fast-Charging Microbatteries with High Energy Density

Today’s wearables, hearables and other products used in space-constrained applications need a safe, fast-charging microbattery with high volumetric energy (VED) and long cycle life in the 1 milliampere-hour (mAh) to 100 mAh capacity range. This presentation will explain how anode-less solid-state lithium technology now enables the development of rechargeable microbatteries that deliver these benefits when implemented with an architecture and manufacturing approach that supports high-volume applications. The latest architecture and manufacturing approaches have removed previous barriers to solid-state technology’s adoption in microbatteries for powering an estimated one billion products shipped annually. These approaches maximize energy density while enabling end-to-end fabrication and packaging in a conventional cleanroom rather than expensive dry (zero humidity) environment. Additionally, the approaches increase VED through the use of an ultra-thin stainless steel substrate, and diced and vertically stacked packaging layers. This also enables a customizable footprint at a desired capacity, and the use of conventional metal terminals for creating a surface-mountable device that is compatible with low-temperature-reflow assembly processes. Attendees will also learn about the opportunities ahead as anode-less rechargeable solid-state lithium miocrobatteries enter the market and transform how wearable, hearable and other products are designed, manufactured and powered.
