Bamboo fiber energy storage material

Can carbonized bamboo fibers be used for flexible energy storage?

The potential application of the carbonized bamboo fibers for flexible energy storage device was also tested and an areal capacitance of ~1.55 F/cm 2 was observed. The device showed no degradation in charge storage capacity on bending. The fabricated device showed an improved performance at higher temperature.

Is bamboo a good thermal energy storage system?

Bamboo has a highly porous structure, particularly in its parenchyma cells , . This porosity allows efficient impregnation of PCMs or other substances, making it an excellent candidate for thermal energy storage systems. In Fig. 2 a–d, these voids are filled with solid-state PCM, giving them a waxy appearance.

How does temperature affect charge storage capacity of carbonized bamboo fibers?

As seen, the area of the CV curves increases with increase in temperature suggesting improvement in the charge storage capacity. The shape of the CV curves is similar at all temperatures suggesting high stability of the carbonized bamboo fibers at higher temperatures.

What is the electrochemical performance of carbonized bamboo fibers?

The electrochemical performance of the carbonized bamboo fibers was investigated in detail. The highest specific capacitance of 512 F/g was observed in KOH electrolyte. The carbonized bamboo fibers showed high power and energy densities of 7.9 kW/kg and 54 Wh/kg, respectively.

What is bamboo-derived carbon?

Recently, bamboo-derived carbon has been attracting considerable attention due to the wide availability of the bamboo tree across the world and highly porous microstructure of the bamboo fibers 17, 18. Yang et al. have used carbonized bamboo after surface activation using KOH for energy storage applications 17.

What are the advantages of bamboo compared to other biomass materials?

Compared with other biomass materials, bamboo has special advantages, such as a high growth rate, high fiber strength and extraordinary large deflection 17, 18. More importantly, its tissue structure is relatively simple and is mainly composed of parenchyma cells (PCs) and fiber cells (FCs) 19.
