2. Lead-acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead-acid_battery

   The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

3. Comparison of commercial battery types - Wikipedia

   Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.

4. VRLA battery - Wikipedia

   en.wikipedia.org/wiki/VRLA_battery

   A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps. A valve regulated lead-acid (VRLA) battery, commonly known as a sealed lead-acid (SLA) battery, [1] is a type of lead-acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel; proportioning of the negative and positive ...

5. Electric battery - Wikipedia

   en.wikipedia.org/wiki/Electric_battery

   The main benefit of the lead–acid battery is its low cost; its main drawbacks are large size and weight for a given capacity and voltage. Lead–acid batteries should never be discharged to below 20% of their capacity, [67] because internal resistance will cause heat and damage when they are recharged. Deep-cycle lead–acid systems often use ...

6. Galvanic cell - Wikipedia

   en.wikipedia.org/wiki/Galvanic_cell

   A battery is a set of galvanic cells that are connected together to form a single source of voltage. For instance, a typical 12V lead–acid battery has six galvanic cells connected in series with the anodes composed of lead and cathodes composed of lead dioxide, both immersed in sulfuric acid.

7. History of the battery - Wikipedia

   en.wikipedia.org/wiki/History_of_the_battery

   A lead-acid cell consists of a lead anode and a lead dioxide cathode immersed in sulfuric acid. Both electrodes react with the acid to produce lead sulfate, but the reaction at the lead anode releases electrons whilst the reaction at the lead dioxide consumes them, thus producing a current. These chemical reactions can be reversed by passing a ...

8. Lead dioxide - Wikipedia

   en.wikipedia.org/wiki/Lead_dioxide

   The most important use of lead dioxide is as the cathode of lead acid batteries. Its utility arises from the anomalous metallic conductivity of PbO 2. The lead acid battery stores and releases energy by shifting the equilibrium (a comproportionation) between metallic lead, lead dioxide, and lead(II) salts in sulfuric acid.

9. Electric vehicle battery - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle_battery

   An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower ...
