As solid-state lithium battery technology grows in adoption — especially for electrical vehicles (EVs) — it is equally attractive for an emerging class of 1 to 100 milliampere-hour (mAh) applications that need a combination of high energy density and small, customizable form factors. The latest solid-state lithium manufacturing and packaging advancements improve microbattery capacity and cycle life without sacrificing performance or energy density and create extensive new options for customizing microbattery shapes and sizes.
