Analyze the important differences between lithium batteries and nickel batteries and the performance advantages of the products

The important difference between lithium batteries and nickel batteries and the performance advantages of products. With the development of the new energy industry, lithium batteries are developing rapidly as a core component. However, the nickel-hydrogen battery market is gradually being replaced by lithium batteries. The difference between lithium battery and nickel battery is as follows. Lithium batteries are suitable for mobile phones, but in digital cameras, due to the relatively large demand for current and much larger power consumption than mobile phones, Ni-MH batteries have more advantages. Lithium battery: The advantage is that there is no memory effect and lighter weight, but it has its defects and high cost. At present, it is small and not fully charged. Lithium batteries can be divided into lithium batteries and lithium secondary batteries, and secondary lithium batteries and lithium batteries. Compared with lithium polymer batteries, secondary lithium batteries and nickel-metal hydride batteries used in ordinary digital cameras, the energy density of light in weight and volume is higher than 48%. Because of this, the production and sales of lithium-ion secondary batteries have gradually surpassed that of nickel-metal hydride batteries. They have less self-discharge, no memory effect, and can be charged and discharged more than 600 times, especially the lithium polymer batteries that have been developed in recent years. This secondary lithium battery is not only small in size, but also not limited by the cylindrical or square shape of general batteries, and is lighter in weight and has more advantages. However, lithium batteries cannot withstand overcharging, and there is a danger of explosion if they are used carelessly. Therefore, a built-in control IC is needed to prevent overcharging, but the cost is relatively increased. Because the specifications of lithium batteries are not uniform, there will be cases where batteries cannot be purchased after organic processing. But it has improved a lot. Ni-MH battery: The price of lithium battery is lower. It has strong versatility, large current and stable environment. The only point is that it is large, inconvenient to carry, and the battery life is short. It is designed from nickel-cadmium batteries and nickel-hydrogen batteries. Great progress has been made in improving the memory effect of nickel-cadmium batteries. The important change is that the use of cadmium in hydrogen storage alloys replaces the original negative number, so nickel-metal hydride batteries are a typical replacement material innovation and pollution caused by nickel-metal hydride batteries. It will be much smaller than nickel-cadmium batteries containing cadmium. Therefore, nickel-cadmium batteries Batteries have gradually replaced nickel-metal hydride batteries. There are several lithium batteries that can be used. The most alternative is no battery. This is very troublesome for users who want to go abroad for a long time or use a lot of nickel-metal hydride batteries. There is no such problem. , Digital cameras that use nickel-metal hydride batteries can often be replaced with alkaline batteries. In recent years, with the popularization of digital electronic products, battery manufacturers have vigorously introduced high-capacity nickel-metal hydride rechargeable batteries, making the technology of nickel-metal hydride batteries advance by leaps and bounds. However, the rapid development of the new energy industry has also brought huge opportunities to the development of the lithium battery industry, so the future development prospects of the lithium battery industry are better than those of the lithium battery industry.
