Lithium batteries and lithium-ion batteries are popular fast cell variety, in literature and in real life, it was discovered that lithium batteries and lithium-ion batteries in use sometimes similar, sometimes interchangeably, the reason is that  lithium battery  and lithium-ion batteries is different and has inherited and developed concepts of the relationship, it is no wonder that people will confuse the two. So-called lithium battery, is to metal lithium do negative activity material of battery General, and lithium ion battery is refers to two species different of can reversible of embedded and off embedded lithium ion of embedded lithium compounds respectively as battery cathode and negative of two times battery system, lithium battery and lithium ion battery of same points is in cathode and electrolytic quality, two species battery are used metal oxide and sulfide as cathode, and to organic solvent - Inorganic salts as electrolyte system. Lithium battery and  lithium ion batt

Core parameters capacity  lithium battery , lithium battery manufacturers generally have specialized equipment for testing to ensure the quality of goods, but for average users, how do you know his new lithium-ion battery capacity is not qualified? Here is a simple test method: multi-meter test method. 1000mAh   Lithium ion battery  are examples (outside of lithium-ion batteries and multi-meters, here, are planning a charger) First of all to understand theoretically what lithium battery voltage values: 1 .Charging voltage: voltage, that is, not working the maximum voltage, typically   4.2V   。 2 .Work   /   Nominal voltage: load voltage working voltage is generally   3.7V   。 3 . He final discharge voltage: the voltage of the battery does not work, have   3V   2.75V   Different designs. To begin testing the battery with a charger, full power voltage   4.2V   And constant current load with multi-meter,   0.2C   (That is,   1000   ×   0.2=200mA   ) Discharge set the multi-

Lithium-ion battery is currently the main power supply for portable mobile device,  ITC  (Communications electronics) industry under the background of rapid development, which also shows a steady growth in demand. These last two years, Governments in the development of new energy sources and low-carbon economy policy is making capacity of the  lithium ion battery  market surge. However, with growth in demand for more powerful lithium-ion battery problem is: how to make the lithium-ion battery in the present volume releases more energy, or that release the same energy can make it smaller. This involves the development of lithium-ion batteries next can have much space. Also, we can transform this problem to how to improve the energy density of lithium batteries. Energy density of lithium-ion batteries is a numerically equal to the battery voltage and capacity of the product, but it's only a few, practical cathode material for lithium-ion battery energy density depends on the energ
