Lithium Poly Batteries
Lithium Polymer batteries make use of dry polymer as it enables manufacturing in a great variety of sizes and shapes than the general lithium ion batteries. Lithium polymer batteries utilize an electrolyte that is in gelled form to enhance the conductance. These batteries are rightly referred as Lithium ion polymer batteries. Lithium poly batteries are flexible and can be produced in a variety of sizes and shapes. The extensive range is the best flexibility of these batteries. The lithium polymer batteries are light weighted. They are light in weight as they do not need metal casings that are highly required for all lithium ion batteries. Moreover, the lithium polymer batteries are very safe as the electrolyte employed in the lithium polymer batteries are not flammable.
The lithium polymer batteries are very expensive in comparison to lithium ion batteries. Their energy density is lower than the lithium ion batteries and the lower cycles count is also lesser than the lithium ion batteries. However, the lithium polymer batteries have become tantamount with other advanced battery technologies. The lithium polymer batteries vary from other batteries mainly in the electrolyte type used. The original pattern of the 1970s used a polymer electrolyte resembling a plastic film that hardly conducts electricity, but permits ion exchange. The polymer electrolyte restores the traditional separator that is soaked with electrolytes. However, the dry designs of polymer batteries are safe as the chances of flammability are totally absent because of the absence of liquid.
The advantages as well as the limitation of using lithium polymer batteries are it has a very low profile such that the batteries resembling thee profile of any credit card is feasible. The flexibility factor is such that the manufacturers are not regulated by any standard cell formats. They can produce any reasonable size batteries economically and in high volume. The light weight enables simple packaging and in many cases you can see the metal shell being eliminated. These batteries are inclined towards improved safety as they have more resistance to overcharge and there is very less probability for electrolyte leakage. The potential to increase the energy density is continuing. Moreover, the lithium polymer batteries have the potential for lesser cost.
The lithium ion and the lithium ion polymer are two systems that are identical, but the lithium ion polymer is distinct as the solid electrolyte is replaced with a porous separator. The technical difficulties in volume manufacturing are trying to be rectified in the lithium polymer batteries. Until date, no improvements have been achieved. However, the cost advantage is not obvious in using or manufacturing the lithium polymer batteries.
