Supercapacitor - Wikipedia

The anode is made of lithium-doped carbon, which enables lower negative potential with a hode made of activated carbon. This results in a larger voltage of 3.8-4 V that prevents electrolyte oxidation. As of 2007 they had achieved capacitance of 550 F/g. 50.4).

Carbon-14 | Answers in Genesis

Carbon-14 dating is a method, based on unprovable assumptions about the past, used to date things that contain carbon (e.g. fossils). It can only give maximum ages of around 50,000 years and yet C-14 has been found in fossils and diamonds thought to be millions and billions of years old respectively.
