BATTERY CONDITIONER EXTENDS THE LIFE OF LI-ION BATTERIES

摘要

LI-ION BATTERIES naturally age, with an expected lifetime of about three years. But, that life can be cut very short - to under a year -if the batteries are mishandled. It turns out that the batteries are typically abused in applications where intelligent conditioning would otherwise significantly extend the battery lifetime. Modern Li-Ion batteries are constructed of a graphite negative terminal, cobalt, manganese or iron phosphate positive terminal and an electrolyte that transports the lithium ions. The electrolyte may be a gel, a polymer (Li-lon/Polymer batteries) or a hybrid of a gel and a polymer. In practice, no suitable polymer has been found that transports lithium ions effectively at room temperature. Most 'pouch' Li-lon/Polymer batteries are, in fact, hybrid batteries containing a combination of polymer and gel electrolytes.
