J.Flex: 3000 mAh flexible battery

The Korean company Jenax introduced a flexible battery with a capacity of 3000 mAh, which can crumple like paper. To demonstrate the capabilities of their development, the creators of J.Flex lined the battery, folded it in several layers, and even formed origami figures.

It seems that the technology arrived just in time - after all, various companies produce “smart” clothes of various types that use a regular battery, which is inconvenient for the user, for several reasons. In addition, the trend of flexible devices is slowly growing, where a reliable flexible battery is also required.

As mentioned above, the capacity of such a battery is quite decent - it is enough for most smartphones, and even more so for wearable electronics with its energy-efficient chips and smart clothes. The battery itself is Li-Ion, there is nothing revolutionary here, the developers have updated only the structure of the battery (no particular details are disclosed here). This type of battery can be used in fitness bracelets , where the bracelet itself can already include a battery, along its entire length. This, as mentioned above, may be smart clothes, all sorts of flexible devices. The J.Flex battery is also very convenient for developers of conventional devices - after all, it requires a minimum of space, the battery can be bent, glued to the walls, customized to fit the shape of the device.



Besides the fact that the battery is flexible, it is also thin, so that such a battery is ideal even for large devices - tablets, large smartphones, etc. The battery thickness is 2.3 mm, the battery itself consists of several square cells with a side length of 80 mm and a capacity of 1000 mAh each. It is clear that the more cells, the greater the capacity. “Sheet” with a length of 3 meters, a width of 0.2 m and a thickness of 0.5 mm will have a capacity of 17,500 mAh. The thickness of the battery may be different, and the capacity of the battery will depend on it.



The battery is not afraid of exposure to water, so there are no problems here either.
