nickel cadmium battery is by Swedish scientists w.

in the 1970 s, invented by Carl jung, the nickel cadmium battery because of its higher than lead-acid battery has the energy, small internal resistance, long cycle life and the advantages of wider temperature range and is widely used gradually.

the advantages and disadvantages of nickel cadmium battery are as follows: ( 1) Service life is long, nickel cadmium battery can be repeated charge and discharge more than 500 times. ( 2) Small internal resistance, can be used in the large current discharge, discharge voltage change is very small. ( 3) Due to the method completely sealed, there would be no electrolyte leakage, also do not need to replenish electrolytes. ( 4) Compared with other types of batteries, nickel cadmium battery to withstand a charge or discharge, the operation is simple and convenient. ( 5) Small self-discharge, long-term storage performance degradation. 6. Can be used in relatively wide temperature range, low temperature performance is good. All landowners with metal shell, so has good mechanical properties. Although the nickel cadmium battery has various advantages, but they have the following two serious shortcomings: first of all, the nickel cadmium battery has the extremely serious 'memory effect'. Battery memory effect is refers to has not completely discharge the battery charging next time can be a part of the charge. In order to eliminate the memory effect of the battery, the battery must be fully discharge, then at the next recharging before charging. Only in this way, the battery can be recharged. Second, manufacturing nickel cadmium battery needs a lot of metal cadmium. This metal toxic and difficult to recycle, which caused great damage to the natural environment. In recent years, with the global environmental protection consciousness enhancement, nickel cadmium battery production and sales have been severely restricted. Issued by the ministry of the European Union RoHS legal limits the use of nickel cadmium battery directly. In addition, the price of the nickel cadmium battery is far higher than that of lead-acid batteries. As a result, many people believe that nickel cadmium battery is obsolete.
