Dear Sirs
I am a portuguese student master degree and do research in rechargeable batteries of aluminium.
I use graphite as the cathode. And I have some problems with the charging the battery, once the voltage does not keep constant after this charge, decreases.
I liked some suggestion yours.
Thanks.
Best regards
Fernando Fonseca
Hello Fernando,
I think graphite should be the Anode? Are you charging it backwards?
If it’s a lithium ion battery, the negative lead should be to the carbon and the positive lead to the aluminum “is it oxide?” cathode. Then charging is positive current flow into the aluminum oxide cathode. Looking at it the other way, electron flow into the carbon anode is charging.
Good luck,
Randy
