Starting with ordinary silicone rubber sealant add as much ultra-fine graphite powder as it is possible to get the sealant to absorb to make a putty. You will need to add so much that the putty will *almost* no longer be mouldable. Form the putty around a wire and leave to cure. You will now have a carbon rubber electrode. If it does not conduct you have not added enough graphite dust. As some silicone sealant contains fungicide this should not be used on the skin.
Adding lighter fluid to silicone sealant thins it down. It may be possible to do this when making the putty to thin it down and get it to absorb more graphite powder. However I have not attempted to thin the mix in this way and as the lighter fluid stays in the silicone putty after curing *never* use this when skin contact is intended.

What is the standard electrode potential of carbon?
It doesn't have one! Check this: if you hook up a carbon electrode to any metal (that isn't as cathodic as carbon, such as gold) then you'll come up with a NEGATIVE potential.
Which element is the reference element is chemistry?
Carbon is the reference element for the definition of the mole. In electrochemistry, the reference element/electrode is the Hydrogen electrode and all electrode potentials are against the hydrogen standard.
How may the production of electrodes be said to have diversified?
The 30-inch carbon electrode was produced in 1927 and the 40-inch carbon electrode followed a year later. Graphite electrodes progressed similarly, but at a slightly slower pace
What element makes up the center electrode post of ordinary flashlight batteries?
carbon
Why is steel not suitable for making the positive electrode?
Actually alkaline batteries use a steel cup coated with carbon as the positive electrode. However the steel is purely structural to support the carbon coating and to prevent leakage of the electrolyte. It does not participate in generating the electricity.
What kind of material is used to make the positive electrode of a dry cell?
The positive electrode is a graphite rod (elemental carbon).
What elements make up carbon rubber?
Rubber basically if vulcanized contains small amounts of Sulphur and Carbon as the main component.

What is used to make tires?
Rubber, steel, rayon or nylon, & carbon black.

What element is in center electron post of a battery?
We find carbon or graphite as the center electrode of a zinc-carbon battery. It's the "common" battery we use in lots of stuff (but not an alkaline battery). That center electrode is the positive one, and the zinc makes up the outer or negative electrode in this battery. In an alkaline battery, manganese dioxide is the center, or the cathode (positive electrode). Powdered zinc will be found as the outer or negative electrode (anode).

How do you make silicon rubber?
Homemade silicone rubber is made by melting silicone until it turns into rubber form. Professionally, there are several ways to produce silicone rubber, most are a mixture of silicone, oxygen, carbon and hydrogen.

What mineral is used to make tires?
As you might imagine there is more than one. Sulfur, Carbon Black, Rubber.
What are lithium --ion batteries and how do they work?
Lithium ion batteries use lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode). Lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge. Ms.Helen Ren
