Planté invented the lead–acid battery, the first-ever battery that could be recharged by passing a reverse current through it. Lead-acid battery Zinc–Carbon battery This battery was invented by Goerge Lionel Leclanche in 1866 In 1888, Carl Gassner made a breakthrough and patented the zinc-carbon dry cell. Zn(s) + 2 MnO2(s) + 2 NH4 + (aq) → Mn2 O3(s) + Zn(NH3 )2 2+ (aq) + H2 O(l) E= 1.5 V E= 2.0 V 7
