The world’s first inventor of the battery was Alessandro Volta, an Italian physicist, the first battery was invented in 1800, using copper and zinc sheets in the middle with a paper shell soaked in salt water to create a battery, and later people in honor of Volt’s contribution to electricity will be the voltage named after Volt.
Lithium battery refers to the general use of lithium-containing materials as electrodes, in which lithium ions have a very important role in the battery.
In the 1970s, Stanley Wijenheim invented the first lithium battery. Wijenhan invented the first lithium battery, in 1980, Gudinav will be the lithium battery battery battery to provide, in 1985, Yoshino Akira will be lithium battery in pure lithium replacement, so that lithium batteries are more secure.
With the lead-acid rechargeable batteries, nickel-chromium batteries, nickel-metal hydride batteries and other batteries were invented, people began to pursue high energy density, with the emergence of cell phones, computers, high-precision electronic devices on the battery requirements are more stringent, the birth of lithium batteries to solve this problem quickly promote the development of modern technology, so lithium batteries are necessary for the development of the times.
Lithium batteries have the highest battery energy density compared to other batteries, which means that lithium batteries can use the least volume and weight to store more power, and secondly, lithium batteries have a longer life, rechargeable batteries have a cycle life limit, and lithium batteries are better, so lithium batteries are the most preferred for other batteries.
Although lithium batteries have better performance, but the cost of lithium batteries and safety needs to be improved, based on lithium and other elements of the rare led to the high cost of lithium batteries, followed by lithium batteries in use is very dangerous, but wherever the use of lithium batteries leakage occurs, so that lithium contact with the air will immediately generate a large number of hot bulging packs of fire, explosion, etc., the lithium battery attenuation also needs to be improved for the long term use of the battery capacity of the device will be Rapidly decreasing.
Although the performance of lithium batteries has been better than other batteries, but this does not seem to meet the requirements, cell phones have to be charged once a day, the computer runs only about 6 hours. But lithium batteries seem to be the limit, excessive growth of lithium density in lithium batteries can cause lithium dendrites, a substance that can easily puncture the battery shell, resulting in lithium leakage, there is a serious danger. For other materials lithium is the most active and smallest metal, at this stage, in addition to changing the battery structure can not find other materials to replace, so the growth is slow.
Solid-state batteries, solid-state batteries at this stage of research in the performance of the lithium battery has been exceeded, and solid-state batteries are also more secure, but solid-state batteries are still in the research stage, solid-state battery electrolyte still can not find a suitable polymer conductive need for temperature, but also prone to fire, sulfide will produce a highly toxic, oxides conductive power is weak, in short, solid-state batteries are still in need of a long time, and now can only be started from the semisolid state.
Each breakthrough in the development of the battery on the road can bring new energy for the development of batteries, lithium batteries are the most ideal battery at this stage, but the battery in the future there is still a longer way to go, let us look forward to it.
