The advantages and disadvantages of nimh batteries Shenzhen battery
China mainland China lithium battery pack manufacturing industry is a fast developing period, especially in high power nimh batteries and capacity of nickel metal hydride batteries are numerous manufacturer to corporate clients from social groups, but nimh battery manufacturers in China of large companies are few and far between, it's quite many small private businesses. Now is a bit more of China is known for its famous for battery in shenzhen, today small make up take you to learn about the advantages and disadvantages of nimh batteries.
nimh battery itself is the relative atomic mass is relatively stable, ruling harmless, green environmental protection battery for health. Nickel metal hydride batteries are generated hydroxyl ions and nickel, constant pressure discharge, fast charge, charging indicator of ontology, support with mixed with with filling, support of old and new batteries, reverse polarity of afterflow, reserve more than three hundred percent of the nickel cadmium battery, battery capacity than the nickel cadmium battery lighter, service life is longer, no pollution to the natural environment at the same time. The defect of nimh batteries is the price is much more expensive than the nickel cadmium battery, the overall performance of lithium batteries are poor.
nimh battery charge with constant current charging ways, according to the battery's ability to accept current can adopt different current for the battery, the charging process don't need to make restrictions, the voltage of battery monomer at the same time, can realize quick charge. Nickel metal hydride battery design is derived from nickel cadmium battery, but on improving nickel cadmium battery memory effect, have greatly breakthrough. The key transformation, in hydrogen storage alloy instead of negative cadmium electrode used in the original, so the nimh battery is representative of the common material innovation. The following 1 for us. No. 2 v1000mahaa5 USB rechargeable nimh battery parameters.

nimh batteries advantages:
1. High energy density, the nickel cadmium is his 1. 5 times;
2。 The battery voltage is 1. 2 v - 1. 3 v, and nickel cadmium battery fairly;
3。 No memory effect, long cycle life,
4。 Can be subject to large current discharge, overcharge and over discharge ability;
5。 No pollution, healthy environmental protection batteries.
nimh batteries defects ( Disadvantages)
1。 The price is higher than the nickel cadmium battery, anode materials for rare earth metal alloy material;
2。 Self-discharge rate.
3。 Charging time long,
4. Net weight is heavy, compared with lithium battery
5. Capacity is smaller than the lithium electricity,
6. Battery discharge time is too short
