The iPhone Air’s Real Breakthrough Is Its Battery:

The iPhone Air may grab attention with its ultra-thin profile and miniaturized logic board, but experts say the real innovation lies deeper inside: its battery technology.

“The battery in the new iPhone is pretty remarkable,” said Gene Berdichevsky, co-founder and CEO of battery materials company Sila, in an interview with TechCrunch. “The completely arbitrary, two-dimensional shape — you look at it, and it’s pretty amazing. It’s a revolutionary piece of battery tech.”

Berdichevsky speaks from experience. As Tesla’s seventh employee, he led engineering on the original Roadster’s battery pack, which helped set the standard for modern EV batteries. Today, his company Sila develops silicon anode materials for both consumer electronics and, soon, electric vehicles.

The breakthrough comes from Apple’s patented metal can battery design. Unlike the pouch cells common in most devices — which use soft plastic casings prone to swelling — Apple’s approach encases the entire cell in a metal shell, adding strength and durability.

Apple has long relied on L-shaped batteries in its iPhones, but these designs had weaknesses. Lithium-ion batteries naturally swell over time, and the sharp interior corner of the L-shape often became a stress point. By contrast, the iPhone Air’s metal can architecture enables batteries that are more robust and can be built in virtually any two-dimensional shape.

“This basically makes it bulletproof,” Berdichevsky explained. “You can now build batteries in any two-dimensional shape you want.”
