The electrodes used in the cells discussed so far, deteriorate with the passage of current and cannot offer a constant emf indefinitely. However, there was a few cells called standard cells, which can maintain a fairly constant emf over very long perio..

Standard cell - The electrodes used in the cells discussed so far, deteriorate with the passage of current and cannot offer a constant emf indefinitely. However, there was a few cells called standard cells, which can maintain a fairly constant emf..

The cells discussed above use a liquid electrolyte, one cathode and an anode. Some of the major disadvantages of these cells are leakage on long term storage, corrosion due to the use of liquid acidic/alkaline solution, short life, low weightage per kg mass of the ..
