Learn more about lithium-ion batteries and nickel-metal hydride battery

Lithium-ion batteries are electrochemical rechargeable Power sources based on Lithium. They have a high energy density and long life (regardless of the Number of cycles). They are not suitable for devices High Current (Power Tools). A further development the Li-ion Dell Inspiron 6400 battery is the lithium-polymer battery.
Building:

The negative electrode of a lithium-ion Dell Latitude E4300 battery consists of Graphite. The positive electrode contains Lithium-metal oxides (LiCoO2, LiNiO4 or LiMn2O4. The electrolyte solution is a mixture of anhydrous aprotic solvents (ethylene carbonate, propylene carbonate) with low-ethers (dimethyl, diethyl or 1,2-dimethoxyethane) and lithium salts as electrolytes selected.
Charging:

Charging is (similar to the lead acid battery) a PPR process: at the beginning of the charge current is kept constant (Amount depends on the residual stress) until after about a Hour about 80% of capacity is reached. In the second Phase is loaded with a constant voltage, up to about 3 Hours of charging is completed. That is, Lithium-ion DELL XPS M1530 battery are not really fast-charge capable.

The NiMH batteries are designed to the polluting NiCd batteries (heavy metal cadmium) to replace. Both batteries are produced identical and voltage compatible, so they interchangeable. NiMH batteries have higher energy density than NiCd Dell Inspiron 1545 battery reach, but not their Current capacity.
Building:

A perforated film is used as a carrier for the Metal powder forming the negative electrode. The positive Electrode consists of a sheet of black nickel oxide hydrate. A Separator takes the Electrolyte, thereby preventing direct contact with the positive electrode.

The film be wound up, the negative electrode is on the outside, and encased in a metal cylinder. The housing is electrically connected to the negative electrode (negative pole the battery). An electrical supply line from the nickel-tin leads the head of the cell, forming the positive pole.
Charging:

NiMH batteries can be charged with a high current (max. Charging current note) and can therefore be loaded in a few Hours their full capacity. Then allowed but no further Energy intake be to damage the Dell Inspiron Mini 9 battery. Today Chargers recognize the charge of the battery and regulate the charging current accordingly or can detect the timing for terminating the charging process.
