Introduction: Lithium Power Battery

Lithium batteries have the fastest growing battery system. Whenever you want to have high energy density or lightweight power supply then lithium batteries is got that prime importance. For many years, Ni-Cd had been the only one fitting battery for moveable apparatus from wireless communications to mobile computing. After that, Nickel metal hydride and lithium ion evolved in the early 1990s, combating side by side to increase customer's demand. But today, lithium batteries are one of the fastest growing and most potent battery chemistry.

Electrochemistry of Lithium Batteries:

A lithium containing battery is a highly developed battery technology that uses lithium ions as a key constituent of its electrochemistry. During an execution cycle or in redox reaction,

• At Anode: Lithium atoms from the anode are oxidized and release their electrons and become lithium ions.
• At Cathode: These lithium ions move from the anode and go by the electrolyte solution and finally they reach to the cathode, here they got the electrons and electrically becomes neutralize.

The lithium ions are tiny and able to pass through a micro-permeable separator present between the anode and cathode. As lithium has small size i.e., third to hydrogen and helium, so lithium batteries have potential of having a very high voltage and charge storage per unit mass and unit volume.

A large variety of different materials is used as electrodes in lithium batteries but the most widely used combination is that of lithium graphite as anode and cobalt oxide as cathode, which is mostly found in the portable electronic gadget like cell phones and laptops etc.

Other cathode materials are lithium iron phosphate and lithium manganese oxide which is used in electric automobiles and hybrid electric. Lithium batteries normally use ether that is a class of organic compounds as an electrolyte.

How Long Do Lithium Batteries Last?

There are a number of external factors which affect a battery's lifespan on the serviceable life. No doubt, if a battery pack falls below a certain charge power, the pack will close down charging at all. That signals the end of its usable life, though it is possible to restore to life of some dead batteries. The time it takes for this processing is depends on again or manufacturing method and components as well as other external factors.

People who are using the lithium power batteries said that there seems to be an agreement about the average battery pack shelf life. If you take care to store your lithium power batteries properly then you can expect your lithium power battery to last about between 3 to 6 years on a shelf wherever you use it. But it is necessary to keep your batteries away from heat. Extreme heat is the major enemy to the general lifespan of Lithium batteries.

How To Choose The Right Lithium Batteries?

When you are choosing a Lithium power battery, you should keep following characteristics in your mind:

• The first thing that is voltage, which is the requirement of the materials used for the electrodes and can range from 3.2 - 4 V for lithium power batteries and from 1.2 - 2 V for other batteries.
• The battery capacity in milli ampere hours (mAh).
• The operating temperature of the battery.
• The structure and formation of the battery.
• The type of use where you want to use the battery.
• The last but not least the price of battery.

Like lithium power batteries all other batteries have two common features:

Voltage: Voltage of battery is expressed in volts (V). The rechargeable batteries generally have 12 V. For larger cells with voltages of approximately 12 V, 24 V or 48 V, and separate 2 V cells are also used, planned to be set up in series and which have a lifespan of about 10 years.

Capacity: Capacity of battery is expressed in ampere hours (Ah). To increase it, several batteries must be attached in parallel.

When you multiply capacity with voltage, you get the amount of electricity stored in kilowatt-hours (kWh). Depending on these features, you will have to choose the battery type, chemical composition i.e., lead-acid, nickel or lithium and technology.

Batteries have a predetermined lifespan and number of cycles depending on the climate and type of use. In order to increase their lifespan and optimize their operation, it is advisable to follow the storage and use recommendations.

Why Choose A Lithium Battery?

A lithium battery is an electrochemical collector that uses lithium as its chemical element. Any material containing lithium can be the base of a lithium battery. It is for that reason very difficult to tell normally about this type of battery as high volume markets i.e. cameras, mobile phones, etc. and similarly high energy markets i.e. aeronautics, hybrid or electric vehicles etc. do not have the same needs in the account of lifespan, cost or power.
