• Charge often - Older electronic devices commonly used Ni-Cd batteries which benefited from deep cycling - allowing the battery to fully drain before recharging. Li-ion batteries on the other hand benefit from being charged often and early on in a fresh cycle. What this means is that a li-ion battery should be charged well before it is fully drained; think about when you plug your cell phone in to charge at night. You don't need to wait until the battery is running low to recharge it if it is a Li-ion battery.
• Re-calibration - The exception to the above rule about charging is that about every 30th recharge or so, you should allow the battery to be nearly drained before recharging. This helps to re-calibrate the external battery meter on your electronic device. Your cell phone, laptop, or other device displays the amount of battery life left on it's display usually. Re-calibration ensures that your electronic device is giving you an accurate reflection of the actual battery life left since the last recharge.
• Infrequent use - If you haven't used the li-ion battery in a while, you'll want to make sure you only charge it to about 60% of it's maximum charge. The reasoning behind this is that li-ion batteries that aren't used often are at risk for permanent capacity loss; a fully charged li-ion battery in storage will lose a far higher percentage of capacity then a partially charged li-ion battery. This is especially true when stored at warmer temperatures.
• Laptop li-ions - This is for only li-ion batteries in laptop and notebook computers. Most portable computers can function fully without the battery connected when they are connected to an external power supply. During long usage periods, the heat from the laptop can affect the battery itself, removing the battery during long periods of externally powered use can protect the battery.

The Basic Lithium Battery:

• A lithium battery consists of an anode made of graphite and a cathode made of "lithiated" metal oxide, not actually the metal lithium but a chemical mixture containing lithium molecules. The anode and cathode are separated by a non-liquid electrolyte, which completes the chemical action necessary to make it work. While in use, ions of lithium travel from the anode and return to the cathode, while electrons travel from the cathode to the anode, thus producing the electricity.

Safety Issues:

• The chemical composition of lithium batteries carries a potential hazard of severe and life threatening explosion when they are exposed to extreme heat, overcharges, or if the outputs are shorted either by an external connection or a technical failure in the instrument in which they are installed. So lithium batteries must incorporate specific safety features to electronically limit or disconnect their output, or include physically features to reduce internal pressure if abused. The polymer battery improves these features.

The Polymer Separator:

• The separator between the anode and the cathode in a lithium polymer battery contains a highly porous solid polymer composite such as polyethylene oxide or polyacrylonitrile, which changes to a gel when the electrolyte is added. The cells are sealed in a plastic aluminum laminate which ruptures and vents any gases caused by electrolyte oxidation, and shuts the cell down in the case of overcharge, short circuit or high temperature, significantly reducing the risk of explosion.

Size and Shape:

• Since the plates of a lithium polymer battery are cut from die cast materials, they can be stacked like a deck of cards and connected in parallel, giving them the advantage of being made in a wide variety of shapes and sizes. The composition of the polymer separator allows the batteries to be made thinner than competitive types, less than four millimeters. The choice to use a lithium polymer battery remains mainly with the manufacturers of the equipment that will use them.

Cost:

• Because of the nature of the separator, lithium polymer batteries cost more to manufacture. But ability to be made thinner makes them the preferred choice for many applications. So manufacturers of equipment considering using them need to decide if the dimensions of the battery compartment are worth the additional cost. Consumers should be aware of discounted or counterfeit lithium batteries, as they may not have the proper safety features to avoid explosion in abusive conditions.

4 Tips to Extend Your Lithium Battery Life:

• Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half
• Battery Calibration - There are some benefits to fully discharging your lithium battery periodically, for laptops this can be especially important. If you start to notice your battery meter becoming more and more inaccurate, it may be time for some battery calibration. Allow your lithium battery completely drain, then charge until the battery is full again. This will calibrate your battery  giving you more accurate readings
• Consequences of Heat - Another enemy of lithium battery life is heat. If you were to leave your laptop plugged in and running for a year, you should expect the lithium battery capacity to be anywhere between 60% to 80% of it's original max capacity. This is why people that use their laptops as desktop replacements will notice greatly reduced battery life performance after one year of use. This issue can be resolved by removing the battery while using a corded power source
• Battery Storage - If you don't plan on using your lithium battery for prolonged periods of time, then you'll want to reduce the charge level to 40% and place the battery in the fridge (not freezer). Storing the battery at 100% charge level applies unnecessary stress and can cause internal corrosion. On the other hand, if the charge is too low, the battery can become permanently unusable, due to battery self discharge

What is lithium-ion batteries?

 

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which a lithium ion moves between the anode and cathode. The lithium ion moves from the anode to the cathode during discharge and in reverse, from the cathode to the anode, when charging. Lithium-ion batteries can be formed into a wide variety of shapes and sizes so as to efficiently fill available space in the devices they power. They're generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for lithium-ion batteries. Plus there is no issue with the memory effect, like the nickel-cadium does. When a nickel-cadium battery is recharged before it discharges the majority of its power, it essentially "forgets" that it could fully discharge to begin with. This problem is termed the memory effect.

What is lithium ion polymer rechargeable battery?

It's a high energy density, 3.6V/3.7V battery that is not compatible with ordinary batteries, but is widely used in the portable equipment market. It uses lithium metallic oxide (LixCoO2, LiNiO2, LiMnO4) in its positive electrode (cathode) and carbon material (LiXC6) in its negative electrode (anode), with electrolyte LiPF6, LiAsF6 etc, and the Lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge, namely Rocking Chair Batteries (RCB).

Lithium ion polymer rechargeable battery similar to the Lithium-ion but with a solid polymer as electrolyte. Some gelled conductive material is added to promote conductivity. It utilizes the latest technology to become available for consumer use in products such as portable computers, PDA, cellular phones, blue tooth, portable DVD and military electronics etc. Lithium-ion polymer batteries have high voltage per cell, and excellent energy on both a weight and volume basis. Additionally, they can be made in very thin and large footprint configurations. Lithium-ion polymer batteries use liquid Lithium-ion electrochemistry in a matrix of conductive polymers that eliminate free electrolyte within the cell. For operating effectively over a broad range of temperatures and conditions, Lithium-ion polymer batteries contain no metallic Lithium anodes

About Rechargeable Batteries

• Function

Using a charger, these batteries can be recharged many times. Rechargeable batteries are used in automobiles, consumer electronics, storage for solar arrays and electrical vehicles.
• Types
• The most common types of rechargeable batteries are lead-acid, nickel cadmium, alkaline, nickel metal hydride and lithium ion. Lithium ion batteries are considered the most advanced rechargeable battery type and are used in most contemporary consumer electronics.
• Size
• Rechargeable batteries come in many shapes and sizes from automobile lead-acid type batteries to laptop and small digital camera batteries. The size is determined by the type of technology used and the design of the device in which the battery will be placed.
• Features
• The main feature of a rechargeable battery is self-evident--it can be charged multiple times. Secondary features that differ depending on the type of battery include:
• Self-Discharge: This effect occurs within the battery cells causing the battery to lose power over time even when not in use.
• Memory Effect: An effect mostly witnessed in Nickel Cadmium batteries, the battery seems to lose its maximum energy capacity if charged multiple times without being fully discharged.
• Energy-to-Mass Ratio: This refers to the energy density of the battery.
• Currently, Lithium ion batteries are the best performing rechargeable batteries if considering the above features.
• Considerations
• Many people avoid rechargeable batteries when given a choice because of a perceived higher cost. When you consider that rechargeable batteries can be reused multiple times, the savings of using them as opposed to one use batteries becomes clear
