the lithium-ion batteries

Although the lithium-ion batteries are nickel-cadmium batteries few memory effect, memory effect is the principle of crystallization in lithium battery will not produce such a reaction, almost. However, lithium-ion battery capacity after repeated charge and discharge will continue to decline, its causes are complex and diverse. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, blocking; from a chemical point of view, is the active anode material is passive,Fly-ying F030, there's the other side to form a stable compounds. Cathode material physics will appear gradually falling off, etc. In short, can ultimately reduce the battery charge and discharge process of free movement in the lithium-ion number.bateria f4809a

Over-charging and over-discharge, lithium-ion batteries will cause permanent damage to positive and negative, from the molecular level, intuitive understanding, excessive discharge of carbon anode will lead to excessive release of lithium ion and makes it appear lamellar structure collapsed,dv1000 battery, over- will charge too much into the negative electrode of lithium ion hard carbon structure to go,compaq n400c battery, and make some lithium-ion can no longer be released. This is also why the lithium-ion batteries are usually equipped with charge-discharge control circuit reasons.
