BatteryWe have reported about Nokia getting a patent on foldable battery. Now one more Battery patent reveals a new flexible battery design which looks like a “Swiss roll”. The patent clearly mentions about requirement of such Batteries for flexible devices which can be mechanically conformable, while maintaining robust and reliable product configurations.

As electronic devices continue to become more sophisticated, these devices provide an increasing amount of functionality and features, and additionally these devices continue to have different forms, such as dynamically flexible devices or mechanically conformable devices, for example. As consumers demand increased functionality from electronic devices, there is a need to provide improved devices having increased capabilities while maintaining robust and reliable product configurations

Swiss roll design of this battery is explained as,

The apparatus includes a single battery ribbon and vacuum packaging. The single battery ribbon comprising a first portion, a second portion, and an interconnecting portion between the first portion and the second portion. The first portion comprises a first block. The second portion comprises a second block. The first portion, the second portion, and the interconnecting portion form a continuous single layer comprising an anode and a cathode. The vacuum packaging surrounds the single battery ribbon. The vacuum packaging comprises a middle connecting portion configured to contact a first side of the interconnecting portion and a second opposite side of the interconnecting portion.

One more example of a device which can use such kind of battery is multi-function portable electronic devices, which we use in daily lives.

According to one example of the invention, the flexible battery 10 may be used in a multi-function portable electronic device. However, in alternate embodiments, features of the various embodiments of the invention could be used in any suitable type of portable electronic device such as a mobile phone, a gaming device, a music player, a notebook computer, or a personal digital assistant, for example. In addition, as is known in the art, the portable electronic device can include multiple features or applications such as a camera, a music player, a game player, or an Internet browser, for example. It should be noted that in alternate embodiments, the portable electronic device can have any suitable type of features as known in the art.
