(“Unlike batteries, which store energy chemically in the material of their electrodes, a capacitor stores energy physically, on the electrodes’ surfaces”)

Note:
(a) “THE Goodwood Festival of Speed is rapidly becoming Britain’s de facto national motor show. Its backdrop, Goodwood House, is home to the Dukes of Richmond, the first of whom acquired his title by the clever expedient of being an illegitimate son of Charles II.”

(The fourth creation of the dukedom of Richmond was in 1675, when Charles II granted the title to Charles Lennox, his illegitimate son by Louise de Keroualle, Duchess of Portsmouth)

(b) “Supercapacitors also last longer than batteries. Repeated cycles of charging and discharging degrade a battery’s chemical components. This means that after a few thousand such cycles most lithium-ion batteries are giving up the ghost. According to Mr Gonzalez, supercapacitors can keep going for 1m cycles.”

give up the ghost (vi; King James Version of the Bible (1611), Gospel of Mark, 15:37 [qv]): "to die"
