纸电池是一种片状纤维素所制成的电池，由于和片状纤维素和纸相似，故得名。

它的制造方法是在片状纤维素上面填满了排列整齐的碳奈米管。碳奈米管是作为电极，用以导电。它的功用既像锂离子电池，又像超级电容器。相较于一般传统电池，它能提供一个长期，稳定的功率输出，并像超级电容器一样能快速放出高能量。一般传统电池是将数个单独的组件组合起来，然而纸电池却是将所有的电池组件集合在一个单一的结构内，使之更加有性能。

A paper battery is an electric battery engineered to use a spacer formed largely of cellulose (the major constituent of paper). It incorporates nanoscale structures to act as high surface-area electrodes to improve conductivitiy.

In addition to being unusually thin, paper batteries are flexible and environmentally-friendly, allowing integration into a wide range of products. Their functioning is similar to conventional chemical batteries with the important difference that they are non-corrosive and do not require extensive housing.Paper batteries has a record of 4 world records.
