Gaston Planté, a French physicist, developed the Lead acid battery as a result of his research and ideas. In fact, the physicist was specifically researching the polarization that exists between two identical electrodes in 1859. Consequently, his work laid the foundation for one of the earliest rechargeable battery technologies. Furthermore, this discovery marked a significant milestone in the field of energy storage and electrical engineering. Plante put plates into liquid solutions. These plates were made from different materials. He wanted to study how the material in each plate changed the amount of energy and voltage produced. Energy refers to the power the plates can create. Voltage is the force that pushes electricity through a circuit. Capacity means the amount of energy the plates can store. Voltage refers to the strength of the electrical power produced.
Plant found that polarization levels change depending on the substance used. Polarization means how much the electric charges in a material shift in one direction. Different materials make these charges shift by different amounts. The French Academy of Sciences released “Research on Voltaic Polarization“, which summarized the findings of his research, in 1859. The French scientist made an important discovery. He found that the secondary current was strongest when it flowed through a circuit made of lead plates. Moreover, this observation highlighted the unique conductive properties of lead in such applications. Additionally, it demonstrated the material’s ability to enhance current flow compared to other options. Consequently, this discovery proved to be a significant advancement in understanding circuit efficiency.. These plates had rubber strips between them. The rubber strips kept the plates apart. Rubber does not allow electricity to pass through it.
Advancing Energy Storage
The scientist placed the circuit in a solution of sulfuric acid. This acid is a strong chemical that can break down other substances. The current produced by the circuit was significantly higher than the current generated by other materials in the experiment. Moreover, this finding highlighted the circuit’s superior efficiency and potential for practical applications. Additionally, the comparison underscored the limitations of other materials in achieving similar results. Consequently, this discovery proved crucial for advancing further research and development in the field.
The lead acid battery was invented more than ten years before the first mechanical energy generator was introduced. However, the lead acid battery needed some help to charge because it was just a backup energy source. Zenobe Gramme is known for making the first dynamo. A dynamo is a machine that can change mechanical energy into electrical energy and back again. This made it easier to charge the lead acid battery created by Plante.
Innovation of Lead Acid Battery
There was no real-world use for Gaston Planté’s discovery of the fundamentals of battery production and operation in 1859. Nearly two decades later, Thomas Edison invented the incandescent light bulb. This gave Gaston Planté’s discovery its first practical use in 1879. In 1886, Gustave Trouvé built the first electric tricycle. He also created a battery-powered submarine in the same year. These inventions were important because people could now use the Planté battery in real life. The Planté battery is a type of rechargeable battery that stores energy for repeated use.
Manufacturing Process of Lead Acid Battery
However, they still didn’t know how to use the Planté battery in the production process of lead acid battery. The Planté battery is a type of rechargeable battery that stores energy. It is often used in power storage systems. But they still didn’t know how to use it correctly in manufacturing tasks. They were unsure how to make it fit into their work. Faure’s improvements greatly increased the capacity of batteries and led directly to their manufacture on an industrial scale, sometime around 1881.He suggested a new method called the “mixed plate” , of lead dioxide and lead sulfate, which serves as an active material.
The plates go into sulfuric acid. This is a very strong liquid that can cause a chemical reaction. It helps electricity flow between the plates. The mixture contains oxide, sulfuric acid, and water. The elements received electrical charge. The process went on. It kept going until lead and lead dioxide became active masses. Lead dioxide is a compound where lead is combined with oxygen. These materials store and release energy effectively in batteries.
The first Artificial lighting system
By order of the Austrian Emperor Franz Josef, Gaston Planté installed the first artificial lighting system in history in 1883. The artificial light resulted from the combination of using dynamo motors and Planté batteries. With its use in the Schönbrunn Palace, the invention of the lead-acid battery definitively established itself as one of the leading inventions of the 19th century.
Attempts of Industrial Production of Lead Oxide
To make lead oxide, it was customary to melt lead in a reverberatory pot. When the molten lead came into touch with the air, oxide began to form on the surface. The amorphous oxides generated were difficult to manage in terms of their chemical compositions and granulometries. Ernest Volkmar came up with the idea to switch from using a lead plate to a grid. This change was a big improvement. Later, people started using grids made from an alloy containing antimony. An alloy is a mix of two or more metals. In this case, they used antimony and lead to strengthen the grid. This new alloy grid replaced the older grids, which were made from pure lead. The grid increased the percentage of active material while decreasing the percentage of metallic lead.
Borton and shimadzu Methods
The Barton Method and the Shimadzu Method, Two Subsequent Advances in Oxide Production, George Barton developed a novel method of producing oxide and patented it in 1898. The researcher used lead that had already melted (at temperatures between 400 and 450 degrees Celsius). A mechanical blade spun inside the pot. It spread tiny droplets of liquid lead into the air. The environment around the droplets was very hot and filled with oxygen. These minute drops reacted with the oxygen in the pot as they traveled through the highly oxidizing environment. Moreover, as the drops moved further, they progressively underwent chemical changes. Consequently, this reaction allowed them to eventually reach the desired degree of oxidation. Furthermore, this process demonstrated the effectiveness of the oxidizing environment in facilitating the intended transformation. An airflow carried the powder to the container. This airflow had oxygen in it, which can help things burn more easily.
Oxidation Process
In 1926, other scientists made new discoveries about oxidation. These advancements built on the work of Genzo Shimadzu. Oxidation is a process where a material loses electrons. This can cause rusting in metals or changes in other substances. The technique basically involved adjusting the pigments grinding mechanisms to the oxidation process. They placed lead spheres inside a ball mill. A ball mill is a machine that grinds or crushes materials into smaller pieces. It has a rotating drum with balls inside. The drum spins, and the balls hit and break the materials into tiny bits. The motion of the machine caused the spheres to rub against each other. This friction created heat. The heat was enough to oxidize the surface of the spheres. The oxidized material then turned into powder.
Shimadzu used lead below its melting point (about 270°); however, Barton employed molten material instead. Moreover, this difference is the key distinction between the Barton and Shimadzu techniques. Additionally, this variation in approach significantly influenced the efficiency and outcomes of their respective methods. Consequently, understanding this distinction is crucial for evaluating the advancements in lead-processing techniques in lead acid battery. These two processes continue to serve as the technical foundation for the manufacture of the raw materials for lead-acid batteries.
