The Advantage of the Li-Ion Laptop Battery

The development of the Li-ion battery comes from lithium battery, so before introducing the Li-ion battery, let us introduce the lithium battery. Lithium battery cathode material is lithium and anode metal is carbon. When charging the battery, the battery positive electrode of lithium ion on the formation of the resulting ion motion to cathode through the electrolyte.

As the carbon negative electrode were layered structure, it has a lot of micro, to the lithium ion on the anode embedded in the pores of the carbon layer, the more embedded lithium-ion, the higher the charge capacity. You can also look for rechargeable batterie online at

Similarly, when the battery discharged, embedded in the negative ion of carbon of lithium-ion more higher discharge capacity. In Li-ion charging and discharging process, the lithium ion is from the positive to negative and then to positive state of motion.

Li-ion battery has the following advantages:

1. Single battery voltage as high as 3.6-3.8V.

2. Energy than the large, the actual ratio of current to achieve energy 100-115Wh/Kg and 240-253Wh/L.

3. Long cycle life, it can reach 500 times more than normal, some even 1000 times. For small current discharge of electrical appliances, battery lifespan will double the electrical competitiveness.

4. Safety performance is good, pollution-free, no memory effect. Predecessor as Li-ion battery, because lithium dendrite is easy to form a short circuit, reducing its applications: Li-ion battery do not contain cadmium, lead, mercury and other elements of the environment pollution.
