Batteries have play an important role in the daily lives of our life.We disposable batteries can pollute the environment, but not the batteries because they can be recycled used.
With the rise in portable devices such as laptops, cell phones, MP3 players and cordless power tools, the need for rechargeable batteries has grown dramatically in recent years. The batteries were invented in 1859, when French physicist Gaston Plante, lead-acid cell was. With a lead anode, cathode and an electrolyte of sulfuric acid, lead dioxide, the battery was a precursor of today's battery car plant.
Non-rechargeable or primary batteries, secondary DellノートPCバッテリー or produce energy in the same way: through an electrochemical reaction, an anode, cathode and electrolyte. In a rechargeable battery, but the reaction is reversible. When the electrical energy from an external source to a secondary cell, the flow of negative electrons to positive, which is inverted during discharge, and the load cell can be applied restored. The most commonly used batteries on the market today are lithium-ion (Lion), although the nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) were once very common.
When it comes to batteries, HPノートPCバッテリー are not all created equal. NiCd batteries are among the first to be widely available, the secondary cells, but they suffered under a bad problem known as memory effect. Basically, if these batteries are not fully each time they shot were used, they rapidly lose the ability. NiCd batteries have been virtually eliminated in favor of NiMH batteries. These secondary cells have a higher capacity and are only weakly affected by the memory effect, but they do not have a good life. As NiMH batteries, battery Leo have a long life, but they have a better load to operate at higher voltages, and are available in a much smaller and lighter. Essentially, all of high quality portable technology these days take advantage of this technology. However Lion batteries currently not available in standard sizes such as AAA, AA, C or D are available, and they are much more expensive than their older colleagues.
For NiCd and NiMH batteries, can be responsible delicate. You must be careful not to overwhelm them, as this may lead to decreased performance. To avoid this, some chargers switch to trickle charge or just turn off when charging is complete. NiCd and NiMH batteries must be treated, so you should be fully discharged and recharged once again from time to time to minimize the loss of capacity. Lion batteries, on the other hand, have sophisticated chargers to prevent overcharging and should never be exceeded.
In addition, the IBMノートPCバッテリー will die at some point, although it can take hundreds of charges until it happens. When they do not last, it must be disposed in a recycling plant.
