Lithium Ion Battery
Definition and Developments
Lithium-ion batteries are a group of developed rechargeable batteries in which lithium ions are allowed to move from the negative electrode side to the subsequent positive electrode in the course of discharging and later assume the opposite direction in the course of charging. Usually, they are composed of an intercalated form of lithium compound which presume the electrode material hence distinguishing it from the metallic form of lithium utilized in the non-rechargeable lithium batteries (Yang and Hou, 2012).
There are numerous differences which are attributed to both lithium-ion-batteries and lithium batteries. In terms of composition, lithium-ion-batteries use lithium form of compounds in the course of charging and discharging while lithium batteries are made-up of lithium, in its metallic state, as its significant composition (Xu, 2004).
Another crucial difference between the two forms of batteries lies in the fact that lithium-ion-batteries are rechargeable while lithium batteries are not rechargeable. The cathodes of lithium-ion-batteries are composed of the chemical composition: LiMn1.5Ni0.5O4 Spinel while the anode is composed of chemical compounds: intercalated graphite material with an alloy of such metals as Silicon and Sn. While working together, the two electrolytes allow for easier movement of Li ions. In the course of charging, Lithium ions are deintercalated from the cathode side and impacting them into the anode (Xie, Imanishi, Zhang, Hirano, Takeda, and Yamamoto 2009). In the course of discharge, lithium ions are intercalated into the cathode side thus facilitating electrochemical energy storage within these forms of batteries necessary in the translation of chemical form of energy into electrical energy (Dunn, Kamath, and Tarascon 2011).
Lithium-ion-batteries were developed in order to assist in the production of batteries which could be recharged regularly. This need for rechargeable batteries was attributed to the different forms of consumer forms of electronic products which had gained much acceptance across the globe hence the demand for the product. In that case, there are now different types of rechargeable batteries used in such devices as portable electronics which are characterized by fair energy densities; absences of memory effects as well as posses the ability to lose charge at a slower pace whenever they are not in use (Thangadurai, Adams and Weppner, 2004).
The future of lithium-ion-batteries has been perceived as having attained significant levels of development, such that they are growing in popularity in terms of military operations, electric forms of vehicles as well as in the aerospace sector (Yang and Hou, 2012).
Advantages of Lithium Batteries:
There are numerous advantages which are attributed to lithium-ion-batteries: first, they possess a high energy density which allows it to store a larger volume of energy despite its size. Lithium-ion-batteries are also considered to be possessing higher-levels of voltages as compared to other rechargeable batteries which make its usage simpler. For instance, while other rechargeable batteries are used in multiples, lithium-ion batteries can be used in their singulars while discharging lots of energy. Unlike other rechargeable batteries, lithium-ion-batteries posses a long-life cycle thus, they can be used for a substantial period of time (Yang and Hou, 2012).
Commercial viability for lithium-ion batteries commenced in 1991 hence they have at least 21 years in the market; especially, consumer electronics market.
