We live in an era of folding screens and two-nanometer chips, yet the average smartphone user remains tethered to a wall every evening. This episode dives deep into the electrochemical and physical bottlenecks preventing smartphone battery density from scaling alongside our processing power. We explore the "Smartphone Envelope," where batteries must compete for precious millimeters against massive camera sensors and cooling systems, and why lithium-ion chemistry has only improved by a measly three to five percent annually. From the explosive potential of silicon-anode expansion to the…
