History of Cell Phone Batteries — Best Quality 1.5V 1200mah Aa Li-Fes2 Battery

From:CTECHI GROUP Limited     Release time:2019-02-18

Overview:Nickel-cadmium battery is the first generation cell phone battery. It has a low voltage of 1.2V, low capacity and memory effect. It needs to be discharged regularly to maintain capacity, and there is environmental pollution in the manufacturing materials. At present, this kind of battery has been eliminated by the cell phone battery market.

1. Nickel-cadmium batteries

Nickel-cadmium battery is the first generation cell phone battery. It has a low voltage of 1.2V, low capacity and memory effect. It needs to be discharged regularly to maintain capacity, and there is environmental pollution in the manufacturing materials. At present, this kind of battery has been eliminated by the cell phone battery market. Nickel-cadmium batteries consist of two plates, one is made of nickel, the other is made of cadmium, positive nickel and negative cadmium. These two metals react reversibly in the batteries, so the batteries can be recharged. Nickel and cadmium have the advantages of being "strong" and cheap. The disadvantage is that cadmium metal pollutes the environment, the battery capacity is small and the life is short, so nickel-cadmium battery is the lowest-grade battery. Because of cadmium, it has memory effect. Every charge must be discharged first, and it needs to be discharged before it can be charged. Otherwise, its memory function will greatly reduce the charge capacity of the mobile phone. Only after discharging the surplus electricity in the battery, can the battery be charged again. Electricity.


2. Nickel-hydrogen batteries

Nickel-hydrogen batteries have high capacity, no memory effect and little environmental pollution, so people are used to call them environmentally friendly batteries. The voltage is also 1.2V. Nickel-hydrogen batteries are called "nickel metal hydride batteries". Nickel-hydrogen batteries are made of hydrogen ions and nickel metal. The positive and negative electrodes are nickel and hydrogen. They have 30% more reserves than nickel-cadmium batteries. They are lighter than nickel-cadmium batteries and have longer service life, because they do not use harmful elements such as cadmium and have no pollution to the environment and no memory effect. The disadvantage of Ni-MH batteries is that they are much more expensive than Ni-Cd batteries, heavier than Li-ion batteries and worse than Li-ion batteries. No need to discharge before use, but the discharge effect is better after use for a period of time; the price is moderate.

3. Lithium-ion batteries

The development trend of mobile phone batteries is lithium-ion batteries. In the charging process, lithium ions transfer between positive and negative electrodes, which is called lithium-ion batteries. Lithium battery is a kind of high energy density battery with lithium ion as material. Lithium-ion battery is also a kind of smart battery. It can cooperate with special original smart charger to achieve the shortest charging time, maximum life cycle and maximum capacity. Lithium-ion batteries are the best batteries at present. Compared with nickel-cadmium batteries and nickel-hydrogen batteries of the same size, the batteries have the largest reserve of electricity, the lightest weight, the longest life, the shortest charging time, no memory effect and no pollution. Lithium-ion batteries are allowed to be fully charged within 2 hours because of their special technical treatment, and their safety performance is greatly improved. The operating temperature range is wide, and the lithium-ion batteries can work between - 20 +60. High temperature discharge performance is superior to other types of batteries. The voltage of single lithium-ion battery is 3.6V. The positive pole uses lithium compounds and the negative pole is carbon. The specific energy of lithium-ion battery can be more than twice that of nickel-cadmium battery. Compared with the same capacity nickel-hydrogen batteries, the volume can be reduced by 30% and the weight can be reduced by 50%. The life of high-quality lithium-ion batteries can reach 1200 times, which is much higher than other types of batteries. Among the three batteries, the capacity is the highest, but the price is more expensive. The charger is demanded higher and special charger is needed. At present, the majority of mobile phone standard batteries are lithium batteries.
