Advantages and disadvantages of NiMH batteries

Nickel Metal Hydride( NiMH) batteries are a new energy battery with advanced capacity and cleaner than nickel cube batteries, which are made of accoutrements that are veritably friendly to the terrain. The accoutrements used in NiMH batteries are veritably friendly to the terrain. There's principally no pollution to the terrain, but what are the advantages of NiMH batteries in addition to the advanced capacity and no pollution? 

 
 What are the disadvantages of NiMH batteries? 

1. Advantages of NiMH batteries compared with lead- acid batteries and nickel cube batteries. 

 
 1) Advanced energy viscosity. 

 2) The discharge rate can be further than 15C. 

 3) lead- acid batteries and nickel- cadmium batteries are contaminating to the terrain, while nickel- essence hydride batteries are fairly environmentally friendly, principally no pollution to the terrain. 

 4) Longer than NiCd and lead- acid batteries in terms of battery life. 

 5) Nickel- cadmium batteries have a large memory effect, lead- acid batteries are easy to sulphide passivation, nickel- essence hydride battery memory effect is veritably small. 

2, NiMH batteries compared with lead- acid batteries and nickel- cadmium batteries disadvantages. 

 
 1) In terms of product and manufacturing costs, NiMH batteries are more precious. 

 2) The tone- discharge performance is fairly poor, that's to say, the tone- discharge current is fairly large. 

 3) Due to the high energy viscosity, the safety performance is worse than that of nickel- cadmium and lead- acid batteries. 

 
 3 、 The advantages of NiMH batteries compared with Li- ion batteries 

 1) In terms of manufacturing cost and specialized maturity, NiMH batteries are cheaper and more mature;

 2) In terms of cell thickness, NiMH batteries are more controlled and further harmonious than Li- ion batteries. 

 3) In terms of safety performance, due to the fairly low capacity viscosity of NiMH batteries, they're less prone to safety accidents similar as bank and explosion. 

 4) In terms of raw accoutrements , NiMH batteries have more abundant coffers and lithium- ion batteries are fairly scarce. 

 4, nickel- essence hydride batteries and lithium- ion batteries compared to the disadvantages of 

 1) In terms of cycle life, NiMH batteries are shorter than Li- ion batteries. 

 2) In terms of energy viscosity, NiMH batteries are fairly low, and their range is fairly short. 

 3) In terms of high current discharge, i.e. multiplier discharge, Li- ion batteries can discharge at 45C or further, while NiMH batteries can discharge at about 15C. 

 4) In terms of space application, NiMH batteries are fixed spherical, while Li- ion batteries can be soft- carpeted aluminum film, which can be diversified in shape and make full use of the space in the battery cube of the product. 

 5) In terms of low temperature performance, NiMH batteries are much worse than Li- ion batteries in terms of discharge performance. 

 6) in the fast charging performance, NiMH batteries are far worse than lithium- ion batteries, similar as battery manufacturing lithium- ion batteries can achieve 3 to 5C fast charging, while NiMH batteries are better than 1C fast charging, that is, NiMH batteries charging time than lithium- ion batteries charging time is much longer.

The below is a simple overview of the advantages and disadvantages of NiMH batteries made by battery technology masterminds who do battery R&D and manufacturing in batteries. In fact, the advantages and disadvantages of NiMH battery conversion comparison is to see with what type of battery comparison, in order to reflect the comparison, rather than simply their own nature.
