People will think of charging a battery as easy as to fill up a bracket with water, just open the tap until it is full. From the outside, that’s exactly how it works, but inside the battery, it is more complicated. A lithium-ion battery typically charges in two stages the first process is called constant current charging. This is a very simple stage. To charge up your mobile phone or tablet will apply a steady current of electricity to the battery to get all those electrons back to the anode. The charger just decides how much power is coming out...

Lithium is a metal, but it is soft enough to cut with a knift. Lithium is silvery-white in colour. Lithium can float on water and is very light. It is difficult to put out lithium fire. Lithium was one of the three elements produced in large quantities by Big Bang. Lithium can find in variety of areas including seawater, mineral springs, and igneous rocks. Around 27% of lithium used for industry is used in batteries Lithium comes from the Greek word "lithos" meaning "stone" or "rock". When burning, lithium gives off a bright red flame.

The lithium battery was first developed in 1912 by G.N. Lewis but the rechargeable lithium battery only available in the early 1970s.Lithium-ion batteries are rechargeable, because lithium ions and electrons move easily back into negative electrodes.The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first.The electrodes of a lithium-ion battery are made of lightweight lithium and carbon.Lithium-ion batteries have a low self-discharge rate, so it's possible that a battery stored for four years will still be fine. If the voltage of a lithium-ion cell drops below a...

There are three most popular battery type, many people will wonder what their difference is. Here are some points: Nickel Cadmium (Ni-cad) Nickel Cadmium can work in extreme environments, no matter cold or hot weather. And they are extreme temperature tolerance, deep discharge capabilities. They tend to have longer life cycle than NiMH or Li-ion. They have around 700-1000 life cycles. But on the other hand, they have a charging problem which they cannot get completely charged after each use. They will potentially only charge up to the last highest charge. This can shorten the lifespan of the battery. Ni-cad...
