Abstract: An electric supplying holder includes a first cover, a second cover, a flexible battery unit and a third cover. The second cover has at least one first contact point. The first cover is disposed at a first side of the second cover. The flexible battery unit has at least one conducting part and is placed between the first cover and the second cover. The first contact point is electrically connected with the conducting part. The third cover is disposed at a second side of the second cover, and a first accommodating space is formed between the second cover and the third cover.

Abstract: A system for supplying electricity to one or more electronic components on a circuit substrate is disclosed. The system may include a first conversion unit configured to perform a first chemical-electrical energy conversion. The system may also include a first conductor electrically coupled with the first conversion unit and representing a first electrode of the system. The system may also include a second conversion unit configured to perform a second chemical-electrical energy conversion. The system may also include a second conductor electrically coupled with the first conversion unit and representing a second electrode of the system. The system may also include a separator disposed between the first conversion unit and the second conversion unit and configured to separate the first conversion unit from the second conversion unit. The separator may be a portion of the circuit substrate.
