The lithium-ion battery works on ion movement between the positive and negative electrodes. In theory such a mechanism should work forever, but cycling, elevated temperature and aging decrease the performance over time. Since batteries are used in demanding environmental conditions, manufacturers take a conservative approach and specify the life of most Li-ion between 300 and 500 discharge/charge cycles. Counting cycles

A polymer is a large molecule composed of many repeated subunits, known as monomers. Because of their broad range of properties,[4] both synthetic and natural polymers play an essential and ubiquitous role in everyday life. Strictly, polymer is a substance made of long repeating chains of molecules called monomers which may be identical or different. The term polymer is often

Short for The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET), is a transistor used for amplifying or switching electronic signals.  A Field Effect Transistor made using Metal Oxide Semiconductor technology. Controlled by voltage rather than current like a bipolar transistor. MOSFET has a significantly higher switching speed than bipolar power transistors. Suitable for high power circuits, they generate almost

Short for Electric double-layer capacitor.Electrical double-layer capacitors (EDLC) are, together with pseudocapacitors, part of a new type of electrochemical capacitors called supercapacitors, also known as ultracapacitors. Supercapacitors do not have a conventional solid dielectric.EDLC on WiKi: http://en.wikipedia.org/wiki/Electric_double-layer_capacitor

The current delivered by the cell during charging.Charge rate is often denoted as C or C-rate and signifies a charge or discharge rate equal to the capacity of a battery in one hour. For a 1.6Ah battery, C = 1.6A. A charge rate of C/2 = 0.8A would need two hours, and a charge rate of 2C = 3.2A would

Short for Plug-in Hybrid Electric Vehicle.PHEV is a hybrid vehicle which utilizes rechargeable batteries, or another energy storage device, that can be restored to full charge by connecting a plug to an external electric power source (usually a normal electric wall socket). A PHEV shares the characteristics of both a conventional hybrid electric vehicle, having an electric motor and an

The electric energy content of a battery expressed in “Watt hours”. A battery’s capacity is the amount of electric charge it can deliver at the rated voltage. The more electrode material contained in the cell the greater its capacity. A small cell has less capacity than a larger cell with the same chemistry, although they develop the same open-circuit voltage.
