Apple is possibly considering new designs and shapes for its future smartphones. According to Apple Insider, the latest patent application filings by the Cupertino company shows a curved battery design and irregular shape for future iPhones or iPod devices.

Apple has filed two patents with the U.S. Patent and Trademark Office that show a new battery that’s curved and features an irregular shape. Both patent filings – “Curved battery cells for portable electronic devices” and “Non-rectangular batteries for portable electronic devices”, describe different processes for creating the battery. The designs ensure that the battery is manufactured and designed to snugly fit into a shapely and curvy slim body of the device.

The curved batteries description shows that it uses production techniques at par with industry standards, including a set of layers, a cathode, an anode, a separator and active coatings, before manipulating the unit to a given specification. Apple's proposed design uses a flexible pouch to enclose the cell layers created by the separator, which isn’t something new and already exists in some batteries available in the market.

Here’s the description from the filing – “In some embodiments, the curve is formed to facilitate efficient use of space inside a portable electronic device. For example, the curve may be formed at one or more ends of the battery cell to allow the battery cell to occupy a curved and/or rounded space within the enclosure of a laptop computer, tablet computer, mobile phone, personal digital assistant (PDA), digital camera, portable media player, and/or other type of battery-powered electronic device.”

Inventors of both patents are Ramesh C. Bhardwaj, John Raff, Stephen R. McClure, Erik L. Wang and Taisup Hwang.
