Lithium batteries and lithium-ion batteries

Since the vast majority of electronic products such as digital cameras, mobile phones, and laptops now use lithium batteries, the mainstream batteries of laptops are currently used, and the most commonly used are Li-ion batteries. The reason is that Lithium(Li) is more dangerous when used. We all know that lithium is an active metal element. It is not safe to use. There are often cases of combustion and burst when charging. The lithium-ion battery(Li-ion) adds an ingredient that inhibits the activity of lithium. It is an alternative to lithium batteries. Its anode uses a carbon electrode that absorbs lithium ions. When discharged, lithium becomes lithium ions, leaving the battery anode. Arrive at lithium ion battery cathode. When charged, lithium atoms in the cathode Ionize into lithium ions and electrons, and lithium ions move toward the anode and electrons synthesize lithium atoms. During discharge, lithium atoms Ionize lithium ions and electrons from the anode surface of the graphite crystal and synthesize lithium atoms at the cathode. Therefore, lithium in the battery will always appear in the form of lithium ions, will not appear in the form of metallic lithium, of course, there will be no danger of combustion, explosion and so on. Lithium ions move between the anode and the cathode, and the electrode itself does not change. This is the essential difference between a lithium-ion battery and a lithium-ion battery. As a result, lithium power has truly achieved safety, efficiency, and convenience, and the old lithium power has also been eliminated. The way to distinguish them is also quite simple: it can be identified from the battery logo. The lithium battery is identified as Li and the lithium ion battery is Li-ion. Now, the so-called lithium electricity used by laptops and mobile phones is actually a lithium ion battery.

Lithium-ion batteries have advantages that can not be compared with other batteries: high operating voltage; Small size, light weight, high energy; Safe and fast charging; Allow a wide range of temperatures; Small discharge current, no memory effect, no environmental pollution, etc., these determine its mainstream position in notebook batteries.
