Lithium Ion Chemistry would be the Power Behind Today s Laptop Batteries

In case you personal a laptop personal computer, chances are Battery pack supplier very really good that it's probably powered by a lithium-ion (Li-ion) battery. This battery sort has located application inside a wide assortment of consumer electronics, such as PDAs and cell phones. They've gained widespread recognition on account of economic and technical factors, specifically their higher charge to weight ratio.
Lithium-ion batteries have replaced the nickel-cadmium (NiCd) batteries that had been initially made use of to energy laptop computers as well as the nickel-metal hydride (NiMH) batteries that superseded the NiCd laptop battery technologies. They have dominated today's rechargeable battery market place for laptop computers for the reason that they're a great deal lighter than the other varieties of laptop batteries, they retain their charge longer than the other technologies and since they don't suffer in the memory effect phenomenon. A typical lithium-ion battery has two instances the energy density of a typical nickel cadmium battery. Additionally, lithium-ion batteries possess a single cell voltage of three.six volts as in comparison to 1.two volts per cell of nickel-cadmium batteries.
On the other hand, the disadvantages associated with lithium-ion batteries contain: the possibility that a failed battery pack can ignite beneath adverse circumstances, they're far more sensitive to high temperature environments than the other battery technologies in their capability to retain their charge, they might fail if they are totally discharged, and also the inherit chemistry with the battery results in degradation with age as opposed towards the stronger correlation among battery failures and charge/discharge cycles in the older battery chemistries. Lithium-ion personal computer batteries also require that protection circuitry be incorporated in to the battery pack to monitor the battery charge and to provide secure voltage and current levels, also as making sure that the temperature of the battery remains in a protected operating variety.
Cylindrical lithium-ion battery cells are commonly tubular in shape, a great deal like the shape of standard alkaline batteries. Quite a few cells are enclosed inside a plastic housing as well as the person cells are connected in a manner to supply the correct output voltage and to maximize storage capacity (rated in milliamp-hours). Prismatic shaped lithium-ion cells are also accessible, however they are much smaller and are typically applied in devices for instance cell phones where weight and space can be a prime consideration.
You will find several things that affect the life of a lithium-ion laptop battery. Battery degradation is hastened by heat, so storing the battery in a cool atmosphere will prolong its life. Makers typically suggest a storage temperature of around 60°F for the long-term storage of lithium-ion batteries. These batteries, as stated previously, don't retain a memory from partial discharge cycles, so full discharge cycles aren't necessary. In actual fact, partial cycling from the battery will help extend its life. Lithium-ion batteries do have a restricted lifetime like the older battery technologies, but that is somewhat independent of their charging cycles and is chiefly related to their age. A common battery will last only two to 3 years. This is true even when the battery remains unused so it's essential to not buy a replacement laptop battery till it can be prepared to become put into service.
