Nickel metal hydride rechargeable batteries and ternary lithium battery which is better?

Source: 2020 - 04 - 04 12:20 hits: ni-mh rechargeable battery and ternary lithium battery which one which is better than that of nickel metal hydride rechargeable batteries and ternary lithium battery is better? There is no final answer, they said the battery! Such a conclusion would be too hasty, in fact, nickel metal hydride rechargeable battery and lithium battery is relatively both have their advantages, the two are similar, the safety in terms of what you buy. Output power also can choose nimh batteries, with green energy-saving rated output voltage stability. For a handheld portable devices such as mobile phone, you can choose the ternary lithium batteries. What nickel metal hydride rechargeable battery is nickel metal hydride rechargeable batteries, nickel metal hydride rechargeable batteries, the principle of some metal materials has a strong ability of hydrogen production. In the corresponding environment under the premise of temperature and pressure, these metal materials can 'absorb' large amounts of hydrogen, reaction into metal hydride, release the heat at the same time. After that, you heat the metal hydride, they were dissolved, storage of hydrogen in the inside. These 'absorption of hydrogen is known as the hydrogen storage alloy metal materials. The hydrogen storage capacity of aluminum alloy is very strong. In the same environment temperature and pressure difference condition, the unit volume of hydrogen storage density is one thousand times that of the water vapor in hydrogen storage, the equivalent of one thousand under the atmospheric pressure of high pressure hydrogen storage. The advantages and disadvantages of nimh batteries 1. Has a good cryogenic charge and discharge performance; 2. Circulation service life ( Increased to 1000 times) ; 3, green environmental protection, energy conservation and pollution; 4. Development, design and scientific research and technology more perfect than lithium ion batteries. 5. Compared with lead-acid batteries, to increase the energy density, net energy density is 65 watts per hour, the volume energy density of 200 watts per hour per litre. 6, large power, high density, can be made of large current charge and discharge; High temperature resistant performance is poorer, try not to make a battery temperature more than 45 degrees. Otherwise, the service life will reduce rapidly, the resistance of the battery is likely to increase. Excessive charging the battery life is very bad, also can bring the corresponding security risks, so I need to stop when the battery charge. The advantages and disadvantages of the ternary lithium battery 1. High energy density, good system performance, more suitable for the future development trend of new energy car battery, suitable for the weather in the north, ultra-low temperature more stable 2 battery. Without memory, overcharge protection, discharge protection, over temperature protection, over-current protection is one of the several key links, to further strengthen and improve, so as to further perfect the design of the safety precautions and science, make the battery in a state of security and protection work. Compared to lithium iron phosphate batteries, ternary lithium battery is more suitable for today's and tomorrow's electric cars, 3. Ternary lithium batteries for high and low temperature adaptability is strong, can be in - 20 ℃ to 60 ℃ under the natural environment of safe use. Properly on the processing technology processing, also can be in - 45 ℃ under the natural environment of safe use; 4. The ternary lithium battery is a kind of green, environmental protection, energy saving new battery. Regardless of the production, use, scrap, don't carry or produce poisonous and harmful heavy metals such as lead, mercury, cadmium and material. The safety of the lithium battery reaction is generally poor, explosion accidents of safe hidden trouble.
