![]() The electrolyte is a concentrated sulfuric acid solution (H2. Note: It should be remembered that lead-acid batteries are capable of being recharged, which is very important for their use in cars.Īlso, during discharging of lead-acid batteries, electrolyte loses much of its dissolved sulphuric acid. When fully charged, the anode consists mainly of lead (Pb) and the cathode of lead dioxide (PbO2). Hence, from above you can conclude that option A is the correct option to the given question. ![]() This is the best-known rechargeable battery in which lead electrode,$Pb\left( s \right)$ is used as anode, lead dioxide, $Pb\mathop O\nolimits_2 \left( s \right)$ is used as cathode and $\mathop H\nolimits_2 S\mathop O\nolimits_4 \left( \right) \to 2PbS\mathop O\nolimits_4 \left( s \right) 2\mathop H\nolimits_2 O\left( l \right)$. Lead and lead dioxide, the active materials on the plate of the battery, react to lead sulfate in the electrolyte with sulphuric acid. You should know that Lead storage batteries are also known as Lead-acid batteries. The electrolyte is aqueous sulfuric acid. The anode is a grid of lead-antimony or lead-calcium alloy packed with spongy lead the cathode is lead (IV) oxide. They are also known as “accumulators” as they can store energy through reversible chemical reaction. An example: the lead-acid battery used in cars. Lead storage battery, also known as rechargeable battery is an electrochemical cell or group of electrochemical cells that converts chemical energy by reversible chemical reactions and they can be recharged again by-passing direct current through it in the direction opposite to that of its discharge. ![]() Hint: Try to recall that Lead storage batteries are those batteries which are used in our homes Also, they can be charged again by supplying direct current (DC) unlike primary cells which are discarded when they get discharged. ![]()
