Ternary lithium battery and nickel metal hydride rechargeable battery which good?
With the rise of the digital industry to break through, three-way lithium batteries and nickel metal hydride rechargeable batteries are more and more popular with players, and their use is also from the traditional small production process of household appliances (such as: hair dryer electric toothbrush, razor) to the use of intelligent products (such as tablet computers, solar street lights, robots, new energy vehicles, electric vehicles) and other industries.
So ternary lithium battery and nickel metal hydride rechargeable battery which good? In fact, Ni-MH rechargeable batteries and lithium-ion batteries have their own advantages compared to each other, the two are comparable.
I. Advantages and disadvantages of nickel-metal hydride batteries
1, ultra-low temperature charge and discharge performance is good;
2. Service life of circulation system (increased to 1000 times);
3, green environmental protection and energy saving without pollution;
4, the development and design of scientific research technology than lithium ion battery perfect.
5. Compared with lead-acid battery, the energy density has been greatly improved. The net weight energy density is 65 watts per hour, and the volume energy density is greatly increased by 200 watts per hour /L;
6, high power and high density, can be charged and discharged by large current;
Ultra-high temperature resistance performance is poor, as far as possible do not need to let the battery ambient temperature higher than 45 degrees. Otherwise, the service life will be rapidly reduced, and the internal resistance of the battery may be enlarged.
Overcharging is very harmful to battery life and has associated safety risks, so stop charging when the battery is full.
Advantages and disadvantages of ternary lithium battery
1. High energy density, good performance of circulation system, more suitable for the future development trend of new energy vehicle batteries in the future, suitable for northern weather, ultra-low temperature battery becomes more stable
2. No memory, over charge protection, over discharge protection, over temperature protection, over current protection these several key links can be further enhanced and improved, so that the design of safety precautions is more and more perfect and scientific, so that the battery can also run in the state of safety protection. Ternary lithium-ion batteries are more suitable for today's and future's electric family cars than lithium-ion iron phosphate batteries
3. Three-way lithium ion battery has strong adaptability to high and low temperature, and can also be used safely in the natural environment of -20℃--60℃. After the correct solution on the production process, it can also be used safely in the natural environment of -45 ℃;
4. Ternary lithium-ion batteries are green, environmentally friendly and energy-saving. No matter they are processed and manufactured, used safely or scrapped, they rarely contain and do not cause all toxic and harmful heavy metal elements and substances such as lead, mercury and cadmium;
The reaction of lithium ion battery is generally poor in safety and has the safety risk of explosion accident. The high temperature structure of nickel cobalt aluminum is unstable, resulting in poor high temperature safety, which is very easy to lead to safety risks.
So, three-way lithium battery and nickel metal hydride rechargeable battery which good? It depends on what you buy security for use. To output power can also choose nickel metal hydride battery, green energy saving output rated voltage and stable. Such as used in mobile phones handheld portable small devices can choose three-way lithium-ion batteries.
