science: lead acid batteries on relativity steroids

yeah! your car battery is on (special) relativity steroids! newscientist reports of research conducted on the relationship between special relativity and lead-acid battery performance apparently by 80%. i've not read the paper so i cannot comment. based on the article, this is because lead atoms attract electrons about 60% faster. mass of matter is composed of rest mass which is the mass of it when at rest and relativistic mass which is the mass it induces temporarily when in motion. total mass of matter in motion is the sum of its rest mass and relativistic mass. faster the speed higher the relativistic mass. higher the relativistic mass higher the total mass. and cite: "according to relativity, this gives the electrons higher effective masses, increasing their binding energy to the electrode that attracts them and thus their voltage."

The transfer of electrons between two forms of lead in the batteries yields a potential of more than 2 volts, higher than most other batteries. But why they are so good has been a puzzle. Lighter weight tin, for example, which sits one row above lead in the periodic table, is too feeble to power a battery.
Without these relativistic effects, Pyykkö and colleagues calculate that lead-acid batteries would generate only 0.39 volts. With them, they predict 2.13 volts, in good agreement with the measured 2.11 volts.
