A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive  Energy density‎: ‎– W·h/‎L‎ (– MJ/L). Lithium-ion batteries are great because they are rechargeable. When the battery is connected to a charger, the lithium ions move in the opposite direction as before. As they move from the cathode to the anode, the battery is restored for another use.

The positive electrode is generally one of three materials: Depending on materials choices, the voltageenergy densitylife, and safety of a lithium-ion battery can change dramatically. This means that lithium-ion batteries can store the same amount of power as other batteries, but lithium ion battery principle this in a lighter and smaller package.

However, one downside to lithium ion battery principle batteries is that they take much longer to charge than other batteries. And of course, there is always room for improvement in efficiency.

This is where nanotechnology comes in. In order to improve the efficiency and decrease the charge time of lithium-ion batteries, many companies and researchers are using nanotechnology to make better battery materials.

A lot of research is focused on using nanotechnology to make better electrodes.

Using nanomaterials in the electrodes increases their surface area, which provides more places for the lithium ions to make contact. This makes the battery lithium ion battery principle efficient and also makes lithium ion battery principle recharge faster.

These changes should make electronic devices that use lithium-ion batteries e. As particle size gets smaller, the surface area to volume ratio gets larger. Nanoparticles are almost all surface! As for the Dewalt drill, its lithium-ion battery uses nanophosphate for the cathode material.

This technology, originally developed by Professor Yet-Ming Chiang and coworkers at MITalso takes advantage of the increased surface area provided by nanomaterials.

Charging Discharging curves are based on the type of Cathode material used. Lithium Ion batteries are know as maintenance free batteries.

They don't have memory effect. I hope this helped you.
