Currently, nickel cadmium, nickel hydrogen, and lithium-ion rechargeable batteries are widely used in various portable electrical devices, such as laptops, cameras, and mobile devices
In words, each type of rechargeable battery has its own unique chemical properties. The main difference between nickel cadmium and nickel hydrogen batteries is that nickel hydrogen batteries
The energy density is relatively high. Compared with the same type of battery, nickel hydrogen batteries have twice the capacity as nickel cadmium batteries. This means that when not using electrical equipment
When adding extra weight, using nickel hydrogen batteries can greatly extend the working time of the equipment. Another advantage of nickel hydrogen batteries is that; A greatly reduces the number of points
The "memory effect" problem in cadmium batteries makes nickel hydrogen batteries more convenient to use. Nickel hydrogen batteries are more environmentally friendly than nickel cadmium batteries
Bao, because there are no toxic heavy metal elements inside. Li ion has also quickly become the standard power supply for portable devices, providing and
Nickel hydrogen batteries have the same energy, but can reduce weight by about 35%, which is suitable for electrical devices such as cameras and laptops
Preparation is crucial. Li ion has no "memory effect" and no toxic substances, which makes it a standard power source
Key factors.
The discharge efficiency of nickel hydrogen batteries will significantly decrease at low temperatures. Generally, the charging efficiency will increase with the increase of temperature, but when the temperature reaches
Above 45 ℃, the performance of charging battery materials will deteriorate at high temperatures, and the cycle life of the battery will also be greatly shortened.
