Lithium-ion battery cathode material of lithium in the active compounds are usually composed of the negative is a special molecular structure of carbon. Common cathode material mainly composed of licoo2, charging, added to the battery positive pole of the electric potential of the compound to force the release of lithium ions, embedded negative elements were arranged in the lamellar structure of the carbon. Discharge, lithium-ion from the lamellar structure of the carbon precipitation and re-cathode combination of compounds. Lithium-ion movement have a current. Battery Laptop Battery Laptop Battery Laptop Battery Laptop Battery Although the chemical reaction principle is very simple, but in the actual industrial production, the practical problems need to be considered much more: cathode material additives required to maintain the activity of multiple charge-discharge, anode material needed to design the molecular structure Level accommodate more lithium-ion; fill in the electrolyte between the positive and negative, in addition to maintaining stability, but also need to have good conductivity, reducing the battery internal resistance. Although there is little lithium-ion battery memory effect of nickel-cadmium batteries, memory effect is the principle of crystallization, in the lithium battery is almost not produce this reaction. However, lithium-ion battery capacity after repeated charge-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 Dell inspiron 2200 battery Dell inspiron 640m battery accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the passive activity of positive and negative material, 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 charging and discharging process of free movement of lithium-ion number. Over-charging and over-discharge, lithium-ion batteries will cause permanent damage to the positive and negative, from the molecular level, can be intuitively understood, excessive discharge of carbon anode will lead to excessive release of lithium ions and makes it appear lamellar structure collapsed, over- Rechargeable lithium-ion will too hard to go into negative carbon structure, and makes some lithium-ion can no longer be released. This is also why the Dell inspiron b120 battery Dell xps m1210 battery Dell inspiron xps m1710 batterylithium-ion batteries are usually equipped with charge and discharge control circuit of the reasons.
