Battery technology is one of the things holding back further innovation in the mobile space; batteries have certainly improved over the last few years, but they can barely keep pace with the power demands of increasingly power mobile devices. For example, many people can’t make it through a whole day with their smartphones or tablets without having to plug them in.

Further, for as small as batteries have become, they still hog an unfortunate amount of space inside a mobile device chassis. Apple is looking to address that issue somewhat by filing for a patent for a curved battery designed for mobile devices.

Apple curved battery

Such a battery includes a cell built in a set of layers that makes a cathode; the cathode has an active coating, a separator, and then an anode with an active coating. The components are sealed in a “pouch” to form the cell, and then the cell itself can be curved. To curve the cell requires 0.13 kilogram-force (kgf) per square millimeter of pressure using curved plates. The application of 85-degree (Celsius) heat can further form the cell.

This technology, according to the patent, could be used in virtually any portable electronic device, including laptops, smartphones, tablets, and cameras. It’s not too hard to imagine multiple designs that would be possible if the battery inside the unit could have a curve to it; perhaps we’ll be seeing a sexier iPhone in the not-too-distant future, for example.

Apple hasn’t been innovating all that much these days, but at least the company is theoretically and conceptually innovating.

More likely it's for their smart-watch, but we'll see.

That's actually a good theory. Makes sense.

That particular shape reminds me of the HTC One V, and also the HTC Hero. Perhaps they just meant to file a generic curved shape.

Every time I see an Apple patent... I suspect they're just trolling/blocking/stealing a design from competition. I know that's pessimistic, but I don't have a very high opinion of Apple.

And you shouldn't.

And Apple files for a patent on something they didn't even create. I'm always surprised at some of the hardware patents they file for things that are other peoples (ie, the company building the parts for them) tech.

One more example of Apple applying for an overly broad patent in the attempt to control technology for profit. This style of patent is BAD FOR EVERYONE!

Agreed. I was surprised when the patent office denied a couple of their patents for being to broad or nothing to back it up. Before that it seemed like Apple was gonna patent anything and everything not nailed down.

Square battery patents

Rectangle battery patents

Thickness patents

Output patents

Will courts need to use a sine bar and protractors to measure the patented curves?

This type of patent should be denied.

If it's a new battery technology inside the shell then by all means issue a patent but only for shape/size/thickness/output.....just more litigation friendly patent office stupidity.
