Rechargeable batteries: How much temperature can a rechargeable battery depend on? Both NIMH and NICAD batteries operate at 1.2 v. But the volume of nickel-hydrogen is higher than the energy of nickel-cadmium batteries. The memory effect of ni-cd battery is very strong and the memory effect of ni-mh battery is very small. Nickel-cadmium batteries contain cadmium, a heavy metal, which has been banned from use. However, ni-mh battery can not replace ni-cd battery in many power tools because of its excellent high discharge rate. So nickel cadmium batteries are temporarily allowed in the ROSH standard for power tools. The difference between lithium ion batteries and nickel metal hydride batteries: Lithium Ion batteries have more capacity than nickel metal hydride batteries for the same size, so their talk time and standby time are longer and their price is higher than nickel metal hydride batteries. Also, in general, ni-mh batteries can not be used with charge, greatly reduced convenience.The development of the lithium-ion battery led to lithium batteries, and then to lithium-ion battery. Early lithium-ion batteries used pure lithium plates. This kind of lithium battery can catch fire easily and cause danger. It was on this basis that lithium-ion battery was developed. The lithium-ion battery is graphite. Ions Conduct Lithium Ions, not metallic lithium. The security has been greatly enhanced. The lithium-ion battery operates at 3.7 V. Higher in volume than in energy than nickel or hydrogen. Currently, the lithium-ion battery has aluminum, steel, and flexible packaging. In different areas of the market. Some markets are common, such as cell phone lithium batteries. But because of the previous disposable batteries and ni-mh batteries working voltage of 1.2 ~ 1.5 v, the two series of 2.4 v ~ 3.0 v. Most electrical appliances have set this operating voltage standard. Such as Walkman, radio, etc. . So in the area of civilian batteries, lithium batteries can not replace nickel metal hydride batteries. However, in the late development of new appliances, such as MP3, MP4, and so are using lithium as a mobile power supply. So nickel metal hydride, nickel cadmium, and lithium-ion battery in their respective fields can not be replaced by other batteries.
