Flexible ceramic lithium batteries could power Apple smartwatch

“Shortly after an Apple patent for a flexible battery design suitable for the rumored iWatch was published, German site MobileGeeks has shown off a real-life example of a fully-flexible, watchstrap-sized battery from Taiwanese company ProLogium,” Ben Lovejoy reports for 9to5Mac.

“Flexible Printed Circuits (FCP), where components are mounted on a bendable plastic substrate, have existed for several years, but until recently the batteries were the stumbling block,” Lovejoy reports. “The patent shown by Apple still appeared to show rigid batteries mounted on an FCP. FCP Ceramic Lithium Batteries are the latest version of this technology, allowing the batteries themselves to be flexible.”

  1. Such batteries are much weaker than normal ones, and it makes no sense now anyway as the screen has to be firm, not flexible, anyway, and under it there should be enough room for the battery — as it is with small iPods now.

    1. A key selling point for a watch is thinness, even more so than with iPods. Obviously, the screen needs to be non-flexible, but it makes perfect sense to put the battery (along with antenna) into the watch band, and not add thickness to the watch portion.

      Also, you are assuming this product is something like a combination iPod/watch. That assumption would be wrong, because Apple will not do something so lazy and unimaginative. It is much more likely that Apple’s “watch” requires a higher level of power, and a battery that takes up the wasted space in the watchband fills that need.

      1. I am assuming that for iWatch to have some minimal functionality, it will have to have hardware that is not unlike to small iPods in volume.

        So it is unlikely that Apple will need weak superthin flexible battery. Besides, this battery will take bigger volume and weight for the same capacity if Apple would use it instead of normal battery. This is kind of contradictory to the idea.

  2. Battery technology lags too far behind to make a practical smart-watch that is going to be used constantly. If Apple had decent battery tech, the iPhone wouldn’t run out of juice as fast as it does. Battery tech is definitely where Apple should be pouring its money for R&D. Apple is all about mobile devices. Whatever Apple comes up with they’d better fully patent it to the point where it will hold up in the courts.

    I don’t mind wearing a bulky watch as long as its functional. My Casio G-Shock Solar is far from thin and light but I barely notice it’s even on my wrist.
