Lithium nickel-metal hydride battery is relatively cheap

Eight self-discharge NiMH batteries much larger than lithium, Ni-MH fully charged so no more likely to light leakage.

IX, storage capacity of nickel-metal hydride batteries have little effect (not performance), but a greater impact on the lithium, lithium will be used without aging.

Ten, either to the use of nickel-metal hydride storage battery internal resistance than the lithium effect was significantly increased, so the useful life, the nickel-metal hydride battery may not adapt quickly to a large current discharge, but for low current discharge equipment, long-term , the Ni-MH is likely to last longer.

XI, Ni-MH battery memory effect is still comparatively obvious, so after repeated charge-discharge requirements for a full charge and full discharge. But almost no memory effect lithium can recharge it after use. toshiba satellite m30 Battery

Polymer lithium-ion batteries and the difference between normal cells on the electrolyte. 70s in the 20th century, the original design, using a solid polymer electrolyte. Such electrolyte is similar to plastic film, but you can not turn to ion-exchange electronic (to charge or clusters of atoms). Polymer electrolyte replaces the traditional porous separator soaked in electrolyte. Dry polymer electrolyte design allows the assembly of simplification, improved battery mechanical strength, safety, and to create a thin geometry. The thickness of a single cell can be thin to 1mm. Equipment designers can freely according to their imagination to design the shape and size of the battery. Unfortunately, the solid polymer lithium-ion battery is subject to its poor conductivity. Resistance is too high and can not provide the required communications equipment currently high pulse currents, can not drive laptop hard drive. Battery heated to 60 degrees C, the conductivity increased rapidly, but such a requirement is not suitable for portable device applications. - D9 k "d # Y (V6 P% d * {toshiba Portege M500 Battery toshiba Portege S100 Battery

As a compromise approach, the introduction of a number of gel electrolyte. Most current mobile phones on the market of polymer lithium-ion batteries are the gel electrolyte containing the mixture of batteries. Lithium-ion polymer to fix the system, making it the only power source for portable devices polymers. After adding gel electrolyte, lithium ion polymer batteries and lithium ion batteries generally + L, N 4 Y8 z * j0 @
