7 advantages that you should know for Lithium ion Batteries

    Lithium ion batteries have several advantages over other types of batteries, including:

    If you are looking for more details, kindly visit our website.

  • Extremely high energy density. Lithium ion batteries store more energy than other types of batteries for the same size of battery, allowing for ultra-high power densities far exceeding current lithium-ion technology.

  • Excellent charge efficiency. Because of the smart charging algorithm implemented by the BMS, lithium-ion batteries lose less energy during the charge/discharge cycle than other battery types (Battery Management System). This is especially useful when large amounts of energy are being stored (as in EVs and solar energy storage).

  • Extremely high discharge power. High power battery packs with high power cells provide high power on demand to power electric vehicles (EV) and renewable energy storage systems.

  • Reduced self-discharge. Although low self-discharge NiMH batteries are available, lithium-ion batteries are by definition low self-discharge.

  • Extremely high cell voltage. This means that fewer cells in a series string are required to generate a given voltage that can easily power devices.

  • Extremely safe and thermally stable. Intelligent BMS is critical to lithium battery performance; it acts as the battery&#;s brain, responsible for advanced monitoring and management to ensure safety, performance, charge rates, and long lifespan.

The lithium-ion (Li-ion) battery is the predominant commercial form of rechargeable battery, widely used in portable electronics and electrified transportation. The rechargeable battery was invented in with a lead-acid chemistry that is still used in car batteries that start internal combustion engines, while the research underpinning the Li-ion battery was published in the s and the first commercial Li-ion cell was made available in . In , John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino received the Nobel Prize in Chemistry for their contributions to the development of the modern Li-ion battery.

During a discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize. The lithium ions are small enough to be able to move through a micro-permeable separator between the anode and cathode. In part because of lithium&#;s small atomic weight and radius (third only to hydrogen and helium), Li-ion batteries are capable of having a very high voltage and charge storage per unit mass and unit volume.

Li-ion batteries can use a number of different materials as electrodes. The most common combination is that of lithium cobalt oxide (cathode) and graphite (anode), which is used in commercial portable electronic devices such as cellphones and laptops. Other common cathode materials include lithium manganese oxide (used in hybrid electric and electric automobiles) and lithium iron phosphate. Li-ion batteries typically use ether (a class of organic compounds) as an electrolyte.

Lithium ions are stored within graphite anodes through a mechanism known as intercalation, in which the ions are physically inserted between the 2D layers of graphene that make up bulk graphite. The size of the ions relative to the layered carbon lattice means that graphite anodes are not physically warped by charging or discharging, and the strength of the carbon-carbon bonds relative to the weak interactions between the Li ions and the electrical charge of the anode make the insertion reaction highly reversible.
