Why high surface area carbons (high temperature argon annealed) are not so preferred for Li ion battery application?

It is understood that high surface area carbons (>1500 m2 /g ) store Li+ at the surface through many mechanisms and resulting capacity is in the range of 1500 mA h /g . This value is much...

Can we use MoS2 for supercapacitor applications?

Though it has a bandgap (which is unlike graphene) it has a good mobility advantage. Does anyone know of any firm (or high impact paper) reports of MoS2 used for supercapacitor application?

What should the proper concentrations be of the reactants to synthesis emeraldine salt ?

During synthesis I found that when APS is added to a solution of Ani + HCl, even small amount of APS is sufficient to form the green color to solution. Of course the rate at which PANI is formed...

What synthesis method did you use? When we prepare PANI, we see only green or yellow, never red. When a dispersion of the doped conductive form is made, it is green.

Yogesh P Gawli

We make by aqueous method using APS and HCl. Product is green colored no doubt abt that... But beaker shines like metallic paint only during synthesis . I never get yellow color.

Sanjeev Bhardwaj

I TOO NEVER OBSERVED YELLOW COLOR COLOR DURING SYNTHESIS
AND THE METALLIC SHINING YOU ARE TALKING ABOUT, I GUESS, COMES FROM UNDERACTED REACTANTS
