Apple patent application reveals redesigned batteries for thinner devices

“On January 19, 2012, the US Patent & Trademark Office published a patent application from Apple that reveals the next thing in battery designs,” Jack Purcher reports for Patently Apple.

“As Apple designs yet thinner devices, and more importantly, a next generation of devices yet unknown, they need to have the ability and flexibility to shape and contour battery designs that will fit their specific dream designs and form factors,” Purcher reports. “Apple’s invention relates to a battery cell which includes a set of electrode sheets of different dimensions arranged in a stacked configuration to facilitate efficient use of space inside a portable electronic device.”

Purcher reports, “For example, the electrode sheets may be arranged in the stacked configuration to accommodate a shape of the portable electronic device. The stacked configuration may be based on a non-rectangular battery design such as a toroidal design, an L-shaped design, a triangular design, a pie-shaped design, a cone-shaped design, and/or a pyramidal design.”

  1. Build it in sheets with some sheets of different sizes and shapes so that the battery form-fits between the contents of a cavity and the cavity itself. Brilliant, and as always, the way things SHOULD BE… Thank you again, Apple!

  2. Does anyone remember what battery company Apple bought, maybe a decade ago?

    Google and Wikipedia aren’t helping me remember. It may have been the lithium division of Mallory (now Duracell), but I can’t find any verifying information. Tanx.
