PbO2 with graphite, gathering methods?

Recently ive been looking up some ways of manufacturing these infamous PbO₂ anodes..
i read about a member of this site's experience with an graphite stick anode to make KClO₄, and apparently as he saw it, it could nearly run forever.

I believe it was Xenoid?

I have now gathered 100g of pure Pb(NO₃)₂, or well nearly pure..
Pure enough, and a piece of graphite, meant for anode / cathode use.
I have seen different reportings about using graphite substrate for PbO₂ anode..
Some reporting it as worthless and never will work, and then theres the nearly invincible graphite PbO₂ anode ?''Berta''?

I have looked through a few patents, to see what they would use for PbO₂, apparently titanium is used instead of graphite on industrial levels..

As seen here, if the picture / link will be visible, i found that they usually use HNO₃ aswell as Copper Nitrate, but again, this is for titanium sheet, i have found on another site in the comments that the ratio should be 100g lead containing salt and 60 grammes of copper salt

the easiest way I found was: get 100 grams of water soluable lead (lead nitrate, or lead acetate) get 60 grams of water soluable copper (copper nitrate, copper acetate, not chloride PbCl is insoluable in water) mix chemicals with distilled water and 2 drops of dish soap (surfactant, it makes a smooth coating) mix until fully dissolved with a amperage limited power supply attach your graphite electrode to the positive and a piece of copper to the negative. the copper ions take less voltage to reduce therefore they get priority to the cathode forcing the lead ions to the anode where they are oxidized to lead dioxide (solid) you should limit the amperage to as low as possible 2ma per square cm worked well for me. rotate the electrode 90 degrees every 15 minutes for 2 hours minumim. (after 2 hours I had 10 grams of PbO₂ deposited on my graphite electrode. good things come to those who wait

Ive heard that lead acetate ''will never work'', but i have copper nitrate and can easily make more of it..

There is also other methods, using graphite powder and PbO₂ powder, and epoxy glue, attached to a graphite stick, im not sure, but attached to something that would be conductive.

Im writing here to make as few mistakes as possible, as 100 grammes of lead nitrate isnt exactly enviromentally correct, and quite hard to just dispose of aswell..

To sum up my actual question:

would dissolving 100g Pb(NO₃)₂ and 60g Cu(NO₃)₂ in 500 mL water and electrolysing this with a Graphite anode measuring 80 x 50 x 4 mm and a lead cathode measuring 10 x 100 mm along with a surfactant make a proper PbO₂, by the sound of it?

and could it possibly be that Copper Sulfate pentahydrate could replace Copper Nitrate, as its more OTC to get CuSO₄ than Cu(NO₃)₂ where i live..

I have also read that the graphite is nessecary to be of a proper quality, not gouging rods.
The plate i have bought seems very dense and of high quality so for that part i would believe it should work.

sorry.. guess ill take your word for true..

but it is possible that i have confused MnO2 and PbO2, tho it seems unlikely that it was a stick of titanium (which is all ive seen used for MnO2 anodes)
i remember it clearly as being a graphite rock..
oh wait a sec... found it now..

apparently this is using graphite and manganese nitrate, guess i remembered wrong, but the name Xenoid is on there.. is this you or is it somebody else using the same name??

Antiswat - you seem to be a very confused person! The information at that site is from me, yes! It is all about coating Ti rods and MMO mesh with MnO2 for use as chlorate and perchlorate anodes! I am not exactly sure where all this comes into the subject of your post about coating graphite with PbO2.

I often read people trying to manufacture a PbO2 electrode. Are the red/brown electrodes from car batteries not suited for the purpose? These both conduct and are covered with PbO2.
