The nickel cadmium, nickel hydride, lithium ion rechargeable batteries are used in various kinds of portable electronic equipments (such as notebook computers, video cameras, mobile phones, etc), each rechargeable battery has their unique chemical properties. The main difference between nickel cadmium and nickel hydride battery is: nickel hydride battery energy density is higher. Compared with the same type battery, the capacity for nickel hydride batteries are twice as nickel cadmium batteries. That means nickel hydride batteries can greatly prolong the equipments working hours without additional weights for power equipments. nickel hydride batteries have other advantages: reducing the cadmium cell: "memory effect" problem, so the nickel hydride batteries can be used more conveniently and more environment friendly than the nickel cadmium battery, because there is no toxic heavy metal elements inside it.

Li - ion battery has quickly become the standard of portable power supply, Li - ion batteries can provide the same energy as nickel hydride batteries, however the weight can be reduced about 35%, it is crucial for the electronic products, such as video cameras, laptop computers devices, etc. Li - ion batteries have no "memory effect" and do not contain toxic elements, which make them to be the standard power supplies.
Discharge efficiency for nickel hydride batteries would be significantly lower at low temperature, recharging efficiency decreases as the temperature rises, but when the temperature rises to above 45℃, rechargeable battery materials will degenerate under high temperature, the life of the battery will be shorten.
