18650 lithium battery is a kind of lithium ion battery commonly used in electronic products, and is often used as a battery in laptop batteries. We found that the 18650 lithium-ion battery sometimes cannot be charged while using it. Let us explain why.
The world's first lithium-ion battery was born in the United States in March 1976. An oil company engineer uses metallic lithium as the positive electrode and titanium sulfide as the negative electrode. Relying on the movement of lithium ion positive and negative electrodes, current is formed inside the battery to complete the charging and discharging process, and interact with the outside world to form electrical energy.
In daily life, lithium-ion batteries can be found almost everywhere, from electric cars to computer motherboard batteries. Lithium-ion batteries have become an indispensable part of people. We often see various safety accidents caused by lithium-ion batteries. The most impressive is the explosion and fire of lithium-ion batteries. The common causes of fires in lithium-ion batteries are as follows.
According to Tom Hartley, a professor of electrical engineering at the University of Akron, the more the battery is fully charged, the greater the loss of the battery. Lithium-ion batteries work best in a medium charge state, in which case the battery life is the longest.
