Lithium-ion battery

- Nov 30, 2017 -

Lithium-ion  battery: A secondary battery (rechargeable battery) that relies mainly  on lithium ions for movement between the positive and negative  electrodes. During charging and discharging, Li + is  embedded in and ejected from the two electrodes back and forth. During  charging, Li + is removed from the positive electrode and is embedded in  the negative electrode through the electrolyte. The negative electrode  is in a lithium-rich state and the discharge is reversed.
Lithium batteries are divided into lithium batteries and lithium-ion batteries. Mobile phones and laptops are lithium-ion batteries, commonly known as lithium batteries. The  battery generally uses the material that contains lithium element as  the electrode, it is representative of the modern high-performance  battery. The real lithium batteries due to the dangers of large, rarely used in everyday electronic products.
