All-Solid-State Textile Batteries Made from Nano-Emulsion Conducting Polymer Inks for Wearable Electronics

ABSTRACT

A rollable and all-solid-state textile lithium battery based on fabric matrix and polymer electrolyte that allows flexibility and fast-charging capability is reported. When immerged into poly(3,4-ethylenedioxythiophene) (PEDOT) nano-emulsion inks, an insulating fabric is converted into a conductive battery electrode for a fully solid state lithium battery with the highest specific energy capacity of 68 mAh/g. This is superior to most of the solid-state conducting polymer primary and/or secondary batteries reported. The bending radius of such a textile battery is less than 1.5 mm while lightening up an LED. This new material combination and inherent flexibility is well suited to provide an energy source for future wearable and woven electronics.

nanomaterials-02-00268-f002: (a) Structure of the textile battery and (b) flexible and fully rollable batteries made from PEDOT soaked textile that can light up an LED.

Mentions: The textile batteries were constructed from a solid polymer electrolyte sandwiched between a lithium foil anode and PEDOT textile cathode as illustrated in Figure 2a. The polymer electrolyte was composed of high molecular weight poly(ethylene glycol) borate ester [15]. Performance of such polymer electrolytes is comparable with conventional liquid organic electrolytes at room temperature. To make it more flexible the separator/ polymer electrolyte can either be a fabric separator as reported in reference [4] or a stretchable gel polymer electrolyte based on monovalent acrylate polymer matrices [16]. Open circuit voltage of such a textile battery based on PEDOT is over 2.8 V, in contrast, voltages of the batteries based on other conducting polymers such as polypyrrole are around 1 V [14,17]. Thus a reliable, flexible and rollable battery from PEDOT soaked textile can be used to light up an LED due to its high open circuit voltage, even with bending radius smaller than 1.5 mm. Figure 2b shows the battery wrapped around a spatula with a radius of < 1.5 mm and the whole textile battery can also be totally wrapped up into a roll in operation. It should also be noticed that such battery is still in full operation after 100 times bending test.
