Briefly describe the current status of electric vehicle battery technology

Battery technology is a great invention with a wonderful and long history. The earliest original battery can be traced back to 250 BC. The Baghdad battery appeared in Mesopotamia civilization. It was used by British inventor Benjamin Franklin in 1749. A set of capacitors connected in series was used to conduct electrical experiments, and the English word Battery began to be used. Subsequently, in 1786, the Italian anatomist Galvani discovered bioelectricity during the dissection of frogs and published it in academia. In 1800, Volta was inspired by Galvani's frog experiment, using copper, tin, and salt water as the The material successfully made the voltaic battery. In 1836, Daniel of the United Kingdom improved the voltaic stack. He used dilute sulfuric acid as the electrolyte to solve the problem of battery polarization and produced the first zinc-copper battery that does not polarize and can maintain a balanced current, also known as the Daniel battery. Later, French Plantet invented the battery with lead as the electrode in 1860, which was also the predecessor of the storage battery. At the same time, the French Recrans invented the carbon-zinc battery, which brought the battery technology to the field of dry batteries. Ushered in the commercial phase of battery technology. In 1887, the British Hellerson invented dry batteries. Commercial use of battery technology began here and mass production in 1896. At the same time, Thomas Edison invented rechargeable iron-nickel batteries in 1890 and commercialized them in 1910. Produce. Since then, thanks to commercialization, battery technology ushered in an era of rapid advancement. Thomas Edison invented alkaline batteries in 1914, Schlecht and Akermann invented sintered plates for nickel-cadmium batteries in 1934, and Neumann developed sealed nickel-cadmium batteries in 1947. LewUrry (Energizer) developed small alkaline batteries in 1949, ushering in the era of alkaline batteries. After entering the 1970s, battery technology was affected by the energy crisis and gradually developed in the direction of physical power. In addition to the continuous advancement of solar cell technology that appeared in 1954, lithium-ion batteries and nickel-hydrogen batteries were gradually invented and commercialized. For example, my country realized the commercial production of lithium-ion batteries in 1987, and the commercial production of nickel-hydrogen batteries began to take shape in 1995.
