Which is better, CR1620 battery, nickel-metal hydride battery or nickel-cadmium battery?
The difference between lithium-ion and nickel-metal hydride batteries depends on the suitability of lithium-ion batteries for mobile phones, but for digital cameras, it depends on the total flow of lithium-ion batteries is very large and the power used is much greater than that of mobile phones, so nickel The application of hydrogen rechargeable batteries is stronger.
The design of NiMH batteries is derived from NiCd batteries, but great progress has been made in improving the storage capabilities of NiCd batteries. The key change in nickel-metal hydride rechargeable batteries can be described as a typical example of raw material innovation, replacing negative cadmium with hydrogen-storage aluminum alloy. Ni-h rechargeable batteries cause significantly less environmental pollution than nickel-cadmium batteries.
The emergence of nickel-metal hydride batteries has given the industry new expectations for mobile phones, because the cost of this new type of battery is not much higher than that of nickel-cadmium batteries, but the battery capacity has increased significantly. Some designers are also very happy. Compared with nickel-cadmium batteries, nickel-metal hydride batteries are not only more environmentally friendly, but also have less memory effect, making them a very ideal substitute.
Advantages and disadvantages of lithium batteries, nickel metal hydride batteries and nickel cadmium batteries
1. Advantages and disadvantages of lithium batteries
Advantages: no memory, relatively light weight. Disadvantages: increased cost, reduced current, resistance to oversaturation (compared to NiMH).
2. Advantages and disadvantages of nickel-metal hydride rechargeable batteries
Advantages: cheap, practical, large current, environmentally friendly and stable. Disadvantages: Net significant, short battery cycles, memory.
3. Advantages and disadvantages of nickel-cadmium batteries
Advantages: "strong" and low price; Disadvantages: cadmium metal materials cause environmental pollution to the natural environment, small batteries, short cycles, and strong memory.
Both NiMH and NiCd batteries and NiCd batteries are. The volumetric energy density of ni-h is higher than that of ni-cd batteries. Nickel-cadmium batteries have strong memory, while nickel-metal hydride batteries have little memory. In addition, the use of nickel-cadmium batteries containing heavy metal cadmium is currently prohibited. However, due to the excellent characteristics of Ni-cd batteries, nickel-metal hydride batteries cannot yet replace nickel-cadmium batteries in many pneumatic tools.
The volumetric energy density is higher than that of nickel hydrogen. However, due to the working standard voltage of the previous primary rechargeable battery and the nickel-metal hydride rechargeable battery, the two are interconnected. Most high-power appliances already have this standard operating voltage specification set. Therefore, lithium-ion batteries cannot replace nickel-metal hydride rechargeable batteries. At this stage, nickel metal hydride, nickel cadmium and lithium-ion batteries cannot be replaced by other rechargeable batteries.
In lithium-ion batteries, various lithium-ion batteries must have battery protection boards, which have comprehensive functions such as over-current protection, over-voltage protection, and power loss protection. When net weight becomes the main condition affecting product characteristics, rechargeable batteries can be maintained immediately. Lithium batteries are the solution. When the power is high, the safety factor is good, the reliability is high, and the performance-price ratio is high. Ni-MH batteries will have more advantages. .
