""The battery in the new iPhone is pretty remarkable," Berdichevsky told TechCrunch. "The completely arbitrary, two-dimensional shape - you look at the shape, and it's pretty amazing.""
""I just got back from Asia and, and I got a chance to see some of these cells," he added. "It's a revolutionary piece of battery tech.""
""Those are very finicky, and this basically makes it bulletproof. You can now build batteries in any two-dimensional shape you want," Berdichevsky said."
The iPhone Air employs a metal-can battery with a rigid metal casing that surrounds the entire cell, providing increased strength and physical durability. Metal-can cells replace pouch cells that use soft plastic casings prone to swelling and pinch points, particularly in L-shaped designs. The rigid casing allows batteries to be manufactured in arbitrary two-dimensional shapes, mitigates swelling-related failure modes, and enables placement very close to device edges. The shape flexibility permits batteries to snake into irregular internal spaces after circuit board placement, supporting ultra-thin and notched device designs and improving overall internal space utilization.
