Charging method of Lithium ion batteries

The charging method of lithium battery is as well same as lithium ion battery. Because the similarity of these two battery. So it is really more important to taking care whenever you want to charge the lithium ion battery.

The common thing is that whenever you are going to charge your battery then you have to sure that the current will be in the constant balance.

The rate of charge for lithium ion batteries is in between 0.5 and 1C in Stage 1 and the timing period for that is three to four hour. Most of the manufacturers are suggested to charging 18650 cells at 0.8C or less and the efficiency of charging is 97 to 99 percent. The maximum temperature after charging a battery is 9ºF and it would be happen due to the protection circuit. Many times a battery is counted as full charge when the current level goes down.

Lithium Ion batteries are does not need to be charged fully because it is possible that the high voltage may stresses the battery. So everybody must be careful when they going to charge a lithium ion battery pack.

Charging procedure of a lithium ion battery

Today lithium ion batteries are incredibly increasing their publicity in the lithium polymer battery market. The manufacturers companies are widely use this lithium ion battery to make electronic devices. These devices are more useful when the power supply going to fail. So it is really very essential for everyone to know that how to charge lithium ion batteries perfectly.

Here is the charging procedure of lithium ion batteries:

Generally Lithium-ion batteries are charged in 3 stages:

1- CC

2- Balance (not required once a battery is balanced)

3- CV

Lithium-Ion batteries charge is too easily and safely charge and it is not very difficult. Default algorithm 4.2 volts per cell in the battery until it reaches a constant current charge and the charge current to 10% of the initial charge rate decreased to 4.2 volts when it is to maintain the voltage of the exit condition of the charging current 10% drop. And exit normal charging voltage is slightly different from the current manufacturers.

Specification of Lithium ion Batteries

Lithium-ion batteries are lightweight, fully disposable and can pack energy in a small volume – which makes them an attractive power source for hybrid and electric devices.

Lithium-ion batteries have the truth of cathode and anode materials, so depending on the density of energy or voltage lithium-ion batteries are specified in three different categories. The first is the specific energy density second is the volume energy density, and the third is the specific power density. Specific energy density has the ability to keep 150 to 250 W•h/kgs where as Volumetric energy density has 250 to 620 W•h/l and Specific power density have 300 to 1500 W/kg.
lithium iron phosphate cathode and graphite anode have a Titular open-circuit Electromotive Force of 3.2 V and a typical charging voltage of 3.6 V. Lithium nickel manganese cobalt (NMC) oxide cathodes with graphite anodes have a 3.7 V nominal voltage with a 4.2 V max charge.

EnergyHolder providing different types of lithium ion battery pack like mobile phone battery, Ups Battery, e- bike battery, camcorder battery, custom lithium ion batteries where they uses wide range of lithium ion for operating temperatures.

History of Lithium Ion battery

Lithium batteries were first proposed in MS Whittingham’s time. He using titanium sulfide and lithium metal as the electrodes. Lithium batteries in which the negative electrode is lithium metal pose safety. As a result, have developed lithium ion batteries in which both electrodes are made of a material containing lithium ions.

At the University of Oxford, England, in 1979, John Goodenough and Koichi Mizushima presented a chargeable cell to cell voltage high in the range of 4 V using lithium cobalt oxide as the positive electrode and the metal lithium as the negative electrode.

This invention supplies the positive electrode material made possible LIBs. LiCoO2 is a static positive electrode material that acts as a donor of lithium ions, which means it, can be used with a negative electrode material other than lithium metal. By allowing the use of electrode materials static and easy to handle negative LiCoO2 opened a new compass of possibilities for new rechargeable battery systems.

After 1980, Rachid Yazami also demonstrated the two sided electrochemical embolism of lithium in graphite. The Constituent electrolytes available at the time break up during charging if used with a graphite negative electrode, precluding the early development of a rechargeable battery system employing lithium or graphite. Electrolyte is used to demonstrate that lithium may be reversibly intercalated graphite through an electrochemical mechanism. The graphite electrode identify that he is currently the most commonly used electrode in lithium ion batteries business.
