History of power lithium batteries

What is a battery? Essentially, a device that converts stored chemical energy into electrical energy is called a battery. In fact, a battery is a small chemical reactor that generates high-energy electrons for injection into an external device; for example, simply from a chemical power source. From the perspective, the battery can be divided into primary battery, battery, lithium battery, energy storage battery and fuel battery. If extended to physical power, the battery can expand the battery type of solar battery, temperature difference battery, etc. Then how much do you know about battery technology history? Where is the future of battery technology going? What is the current status and future trends of electric vehicle battery technology? Let's expand on the analysis below.

In 1786, the Italian anatomist Galvani discovered bioelectricity during the anatomy of the frog and published it in academia. In 1800, Volta was inspired by the Galvani frog experiment, using copper, tin and brine as materials. The voltaic battery was made in 1836, and Daniel of the United Kingdom improved the "Volt Stack" in 1836. He used dilute sulfuric acid as the electrolyte to solve the problem of battery polarization, creating the first zinc-copper battery that is not polarized and can maintain a balanced current, also known as "denier battery." Later, France's Plante invented the battery with lead as the electrode in 1860, which was also the predecessor of the battery; at the same time, France's Lakeland invented the carbon-zinc battery, which led the battery technology to the field of dry batteries. The commercial phase of battery technology is ushered in.

The dry battery was invented by Thomas Edison in 1887. Commercial use of the battery technology began here and was mass-produced in the United States in 1896. Meanwhile, Thomas Edison invented rechargeable iron-nickel batteries in 1890 and commercialized them in 1910.

Since then, thanks to the commercialization drive, battery technology has ushered in a rushing era. Thomas Edison invented alkaline batteries in 1914, Schlechtand Akermann invented nickel-cadmium battery sintered plates in 1934, and Neumann developed sealed nickel-cadmium battery in 1947. LewUrry (Energizer) developed a small alkaline battery in 1949, which ushered in the era of alkaline batteries.

After entering the 1970s, battery technology was gradually affected by the energy crisis and gradually developed toward physical power. In addition to the continuous improvement of solar cell technology that emerged in 1954, lithium batteries and nickel-hydrogen batteries were gradually invented and commercialized. For example, in 1987, China realized the commercial production of lithium batteries. In 1995, the commercial production of nickel-hydrogen batteries began to take shape.
