Currently on the market used mainly nickel-metal hydride secondary batteries (Ni-MH) and lithium-ion (Li-ion) types. Lithium ion batteries are Battery laptop battery already in volume production of liquid lithium-ion battery (LiB) and lithium ion polymer battery (LiP) two. So in many cases, the battery mark the Li-ion must be the lithium-ion battery. But not necessarily liquid lithium-ion battery, is also possible that lithium-ion polymer battery.
Lithium ion battery is the improved product. Lithium batteries have a long time ago, but lithium is a highly active (remember it in the periodic table of the position?) Of metal, it is not safe when used often in charge when burning, burst case, then there will be a modified lithium-ion batteries, Dell FK890 battery Dell Inspiron 1721 batterylithium element added to inhibit the active ingredients (such as cobalt, manganese, etc.) so that lithium truly achieve a safe, efficient, convenient, and the old lithium batteries also will basically eliminated. As to how to distinguish them from the battery of the label can identify lithium as Li, lithium-ion battery Li-ion. Now, laptops and mobile phones using the so-called "lithium batteries", are in fact lithium ion battery.
The basic structure of modern batteries, including cathode, anode and electrolyte three elements. As a battery, lithium ion battery also has three elements. General lithium-ion technology uses liquid or inorganic colloidal electrolyte, requiring combustible solid shell to accommodate the active ingredients, which increases battery weight and cost, also limit the size and shape flexibility.
