Traditional battery technologies, primarily pouch cells, proved inadequate for the extreme form factor and demanding power profiles of devices like the Ray-Ban Meta. This case study details Meta&rsquo;s innovative engineering journey to develop ultra-narrow, steel can battery technology. It explores the fundamental design shift, the specific challenges in achieving a battery narrower than an adult&rsquo;s pinky finger, and how these advancements enabled the sustained, high-performance operation of integrated AI workloads, cameras, and displays in compact wearable hardware.</p>
