What is lithium-ion batteries? »Its Definition and Meaning [2019]

Lithium-ion batteries, are a tool designed to store electrical energy , which uses as a electrolyte a particle of lithium salt , which is responsible for to get the ions that are required to generate a reversible electrochemical reaction, which occurs between an anode and a cathode, these batteries are also known by the name of Li-ion.

The idea of ​​this device was proposed by MSWhittingham, who had the idea of ​​using lithium metal and titanium sulphide as a kind of electrodes .This served as the basis for the year of 1985 Akira Yoshino, will design a prototype in which I use carbon composite material where I could insert the electrodes of lithium ions and cobalt lithium .When using materials that did not possess metallic lithium the safety to to be able to use them is greatly increased compared to that if they used, which promoted their large-scale manufacturing, originating in that way Li.ion batteries.

The use of these devices today has become very important due to the great advantages they bring , because thanks to them large amounts of energy can be stored, each one providing about 3.7 volts , the same amount generated by three Ni-Cd type batteries the weight is another advantage , since they are quite light and smaller in size when compared to Ni-MH type battery , all this without affecting their energy storage capacity.It is very common that batteries have a percentage of self-discharge , however, Lithium-Ion batteries decrease that percentage significantly, making them more practical, in addition to that during use, as the voltage is discharged does not vary significantly, which avoid the use of circuits that regulate the passage of energy.

However, despite the great uses and advantages that this tool represents, the system is not quite perfect, since they have some failures such as the number of limited recharges that oscillates between 400 and 1000 charges which is a delay compared to those of the Ni-Cd type, so they are considered as consumables.Another element against them is their cost , Since its manufacturing is expensive compared to other batteries, finally its low performance of work in cold.
