Lithium-ion batteries (LIB) are a family of rechargeable batteries having high energy density and commonly used in consumer electronics. Unlike the disposable lithium primary battery, a LIB uses intercalated lithium compound instead of metallic lithium as its electrode.
Usually, LIBs are significantly lighter than other kinds of rechargeable batteries of similar size. LIBs are heavily used in portable electronics. These batteries can be commonly found in PDAs, iPods, cell phones, laptops, etc.
This term is also known as a LI-ion.
When a LIB is discharging, lithium ions move from the negative electrode (anode) to the positive electrode (cathode). When a LIB is charging, lithium ions move in the opposite direction, and the negative electrode becomes the cathode, while the positive electrode becomes the anode.
Some of the advantages of LIBs are:
Some of the disadvantages of LIBs are:
