Li-ion batteries (types)

Li-ion batteries (types)

A lithium-ion (Li-ion) battery is a type of advanced battery in which lithium ions play an important role in
electrochemistry. During a discharge cycle, lithium atoms in the anode are ionized and separated from their
electrons. The lithium ions pass from the anode to the cathode via the electrolyte, where they recombine with their
electrons and are electrically neutralized. The lithium ions are small enough to pass through the anode and
cathode separator's micro-permeable separator. Li-ion batteries can have very high voltage and charge storage
per unit mass and unit volume due to the small size of lithium (third only to hydrogen and helium).
Lithium-ion battery electrodes can be made of a variety of materials. The most common combination is lithium
cobalt oxide (cathode) and graphite (anode), which can be found in cell phones and laptop computers. Other
cathode materials include lithium manganese oxide (used in hybrid and electric vehicles) and lithium iron
phosphate. In lithium-ion batteries, ether (a class of organic compounds) is commonly used as an electrolyte.
3.7 volt 7000 mah lithium-ion battery
This is a 3.7-volt lithium-ion battery with a capacity of 7000 mAh. The Li-ion
battery is one of the most advanced battery technologies on the market. The
primary element in its electrochemistry is lithium ions. Because of its small size,
lithium can easily pass through a micro-permeable separator (third in size only
to hydrogen and helium). As a result, lithium-ion batteries have a very high
voltage as well as a high charge storage per unit of mass and volume.
This 3.7 volts 7000 mah lithium-ion rechargeable battery is commonly used in
GPS, DVD, Tablet PC, Development boards such as Arduino, BBC micro: bit, MP4
Player, Power Bank, Mobile Backup Power Supply, Electric toys, Bluetooth
Speaker, IoT, and Industrial applications.

3.7V 2500mAh 18650 lithium-ion battery
The 18650 battery is a Li-ion rechargeable battery with a capacity of 2500
mAh. This is not a standard AA or AAA battery, but it is ideal for applications
requiring continuous high current or high current in short bursts, such as
cameras, DVD players, iPods, and so on. This 3.7V 2500mAh 18650 lithium-
ion battery is environmentally friendly, safe to use, and has long battery life.
The 18650 battery has a high energy density and is an excellent continuous
power source for your device. It should be used in conjunction with a
protection circuit board that protects the battery from overcharge, over-
discharge of the pack, and over-current draw.
To use the cell in any circuit, simply solder the wires to the terminals or use
18650 battery holders to replace the used cells. Li-ion batteries must be
handled with caution because they are volatile and flammable, and they
should not be handled roughly or punctured. Also, do not overcharge or
discharge beyond a certain point, as accumulated gasses inside may
cause explosions and fires. When using Li-Ion batteries, always use the
protection board.

11.1V 5200mAh lithium-ion battery
The 11.1v 5200mAh li-ion battery is one of the most advanced battery
technologies available. The primary element in its electrochemistry is
lithium ions. Because of its small size, lithium can easily pass through a
micro-permeable separator (third in size only to hydrogen and helium). As
a result, lithium-ion batteries have a very high voltage as well as a high
charge storage per unit of mass and volume.
This 11.1V 5200mAh lithium-ion battery is rechargeable, has low self-
discharge, and has high capacity. These batteries have a longer lifespan
than standard lithium-ion batteries.
