Manufacturing Scale-Up of mAh Class Anode-less Solid-State Lithium Microbatteries

Rechargeable anode-less solid-state lithium microbattery technology has numerous advantages over conventional alternatives. These include higher volumetric energy density (VED), significantly faster charging with a simpler charging infrastructure and the ability to deliver higher discharge pulses than Li-ion alternatives. These flexible form factor, multi-layer stacked batteries built on stainless steel are key to enabling space constrained wearables, hearables and IoT applications. Addressing the difficult challenges of manufacturing scale-up on the path to commercialization requires addressing a number of challenges ranging from materials supply chain and roll-to-roll battery fabrication management to high-speed test and novel ultrathin packaging. Some examples of these coupled with battery performance will be presented.
