Problems solved by technology

While ordinary electronic devices are developing rapidly, batteries have only made modest progress according to Moore's law, mainly due to the energy density and capacity limitations of current materials
Therefore, batteries with reduced charge times and increased charge densities could have profound implications for the design and use of portable electronics and renewable energy devices

Embodiment

[0326] In one embodiment, the footprint of the exemplary electrochemical cell is about 1 cm 2 and a thickness of about 1mm, thus enclosing a 0.005cm 3 volume of. In this example, the composition of an exemplary electrochemical cell is shown below.

[0327]

[0328] In this embodiment of the electrochemical cell, because according to Figure 5A , SEM images show that the porosity of PANI nanotubes is about 28.4%, so the actual volume of PANI is calculated to be about 1.05x10 -4 cm3. in addition,

[0329] In this example, the exemplary electrochemical cell exhibited capacitance, voltage, and energy of about 1.14F, 1.4V, and 0.0003Wh, respectively. in addition, Figure 22 Shown are the gravimetric and bulk densities of asymmetric PANI / / AC devices with NQ redox electrolyte and carbon cloth, normalized by the mass and volume of the electrode (1554 Wh / kg, 1019 Wh / L), by the mass and volume of the electrode and redox electrolyte Normalized by mass and volume (1091Wh / kg, 851...

Abstract

The present disclosure further provides an exemplary energy storage device fabricated from rectangular-tube polyaniline (PANI) that is chemically synthesized by a simple and convenient method. The rectangular-tube PANI, as an active material, is synthesized on a functionalized carbon cloth (FCC) as a substrate, and the obtained composite is immobilized on a stainless steel mesh as a current collector. The present disclosure additionally presents a facile technique for the direct synthesis of PANI nanotubes, with rectangular pores, on chemically activated CC.

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 317,120, filed April 1, 2016, which is incorporated herein by reference. Background technique [0003] The development of high-performance energy storage devices has gained great attention in a wide range of applications. While ordinary electronic devices are developing rapidly, batteries have only made modest progress according to Moore's law, mainly due to the energy density and capacity limitations of current materials. Therefore, batteries with reduced charge times and increased charge densities could have profound implications for the design and use of portable electronics and renewable energy devices. Contents of the invention [0004] Provided herein are methods, devices and systems for growing nanotubes on functionalized carbon cloth. The growth may include the fabrication (or synthesis) of functionalized carbon cloths, the fabrication (or synthesis) of nanotu...
