5. Style 01 What are Lithium Polymer battery 02 Lithium-ion batteries consist of lithium ions which move from the negative electrode to the positive electrode during discharge and back when charging. The lithium-ion batteries use an intercalated lithium compound as one electrode material. The most significant difference between Li-ion and Li- po batteries is the chemical electrolyte between their positive and negative electrodes. In Li- po it isn’t a liquid. Instead it uses a gel like electrolyte Why is it different form lithium-ion batteries A rechargeable cell of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, like mobile devices and  radio-controlled aircraft.

6. First li-po Battery In 1999, Ericsson introduced one of the first mobile telephones with lithium-polymer ( LiPo ) cells to the market . At the time the unit was very small and sensationally flat. 1999 First Li-ion battery 1991 Introduction to polymer battery technology The first commercially available Li-ion battery was brought out by the Sony company of Japan in 1991. It was used to power a video camera and in notebooks .

11. What is a separator Provide a barrier between the anode (negative) and the cathode (positive) while enabling the exchange of lithium ions from one side to the other. On excessive heat, a shut-down occurs by closing the pores of the Li-ion separator through a melting process ..   Electrolyte The main task of the electrolyte is to prevent the flow of electrons through it towards the negative terminal

12. Principle and its significance Li- po Batteries

13. Li- po batteries Principle The principle of operation and construction of Li-polymer batteries are identical to those of Li-ion batteries. These batteries operate on the principle of de-intercalation and intercalation of lithium ions from positive electrode to negative electrode.

ELECTRODE SET SELF DISCHARGE ENERGY DENSITY DESIGN Electrode set In Li-polymer batteries the electrode set consists of a carbon-based substance ( graphite+additives ) pasted onto a metallic substrate. Energy density The energy density of these cells is higher ,Relative to their overall weight. Like Li-ion batteries, they can be easily connected in parallel to allow higher capacities . Self discharge They have low rate of self-discharge. But they should be protected from overcharging, deep discharge and extreme temperatures. Design These can be of any shape unlike li-ion batteries which are usually rectangular. These batteries can be thinner than 1 mm (can be made as similar as a credit card).

20. Electrolyte leakage is less likely and the unit is more resistant to overcharge condition Improved safety Electrolytes are gelled rather than in liquid form, enabling simplified packaging Light weight Advantages Thin and adaptable batteries that resemble the profile of the credit card. Manufactures are not bound by standard cell formats. Very low profile  The main advantage of Li-Po battery cells is that they have about four times the   energy density of nickel cadmium or nickel metal hydride batteries Limitations Expensive to manufacture in small volumes. There is no standard shape Li- po Batteries

22. Article from times now Lithium–sulfur batteries may succeed lithium-ion cells because of their higher energy density and reduced cost due to the use of sulfur. The first such battery was used on an unmanned solar-powered aero plane flight (at the time) by Zephyr 6 in August 2008.
