What is a cable-type lithium-ion battery that revolutionizes the shape of the battery, can be freely bent freely?

Mobile batteries are being released from various manufacturers so that notebook PCs and smartphones can be recharged at their destination, but the shape is quite similar. This is a thing that there is no choice because shape will definitely come up when trying to make a battery, but batteries that can be bent freely, causing a revolution here are being studied.

Experiment connecting batteries and blue LEDs


Since it is the same experiment as attaching a mini scalloped light bulb, of course the LED will light up when the circuit is connected.


This battery ......


Even if it bends quickly, the LED will remain lit


put it back……


Once again, I am bending thoroughly, but there is absolutely no problem.


Test on how the voltage is. The numerical value of the bent state is 4.071.


It stretches 4.071, it does not change at all.


From the side ...


The battery is bent freely, but the numbers do not move at all.


Lithium ion battery is what actually made into a cable type, and it is shaped like a blue LAN cable. I make a knot, but it seems that there is no particular problem in use.


Batteries themselves are made by twisting Ni - Sn (nickel - tin) plated carbon wires and bundling them.


If it is put into practical use, it will not be restricted by the shape of the battery, so the shape of various things will likely change not only for mobile batteries.
