Why are lead-acid batteries more efficient than other aqueous batteries?

Lead-acid batteries recharge efficiently because of the low rate of water electrolysis on lead. The reason is that the hydrogen evolution reaction is impeded on the surface of the lead electrode. As a result, the lead-acid battery can deliver a higher voltage than other aqueous rechargeable batteries.
