1. The difference between lithium batteries and nickel-metal hydride batteries:
1. Under the same volume, lithium batteries have greater capacity than nickel-metal hydride batteries. Therefore, its talk and standby time is longer than that of nickel-metal hydride batteries, and its price is higher than that of nickel-metal hydride batteries. In addition, under normal circumstances, nickel-metal hydride batteries cannot be charged at any time, which greatly reduces their convenience.
2. The volume specific energy of lithium batteries is high. The working voltage of the lithium-ion battery is 3.7V, and its volume specific energy is higher than that of nickel metal hydride. Currently, lithium-ion batteries are available in aluminum shells, steel shells and flexible packaging. occupy the market in thetheir respective fields.
3. Operating voltage standards are different. The working voltage of disposable batteries and nickel-metal hydride batteries is 1.2-1.5V, and the two connected in series are 2.4V-3.0V. Most electrical appliances have already established this operating voltage standard. Such as a portable music player, radio, etc.
2. Similarities between lithium batteries and nickel metal hydride batteries:
Both can provide power easily and say goodbye to constraints, some are common in the market, such as cell phone lithium ; batteries.
