“…Therefore, researchers have been actively investigating and improving electrode characteristics of Ni-MH batteries . However, most research has focused on the active materials for the electrode, whereas additives for the electrode have attracted far less attention [24,25]. Generally, some additives such as hydroxyl propyl methyl cellulose (HPMC), carboxy methyl cellulose (CMC), poly tetra fluoro ethylene (PTFE), carbon black, and commercial adhesive are mixed into a slurry for electrodes when manufacturing Ni-MH batteries on the production line.…”

We optimized the composition of additives for the anode in a Ni-MH battery using the response surface method (RSM) to improve the electrode discharge capacities. When the amount of additives was small, the discharge characteristics of the electrode were degraded by charge-discharge cycling due to the low binding strength among the alloy powders and the resultant separation of the powder from the electrode surface. In contrast, the addition of a large amount of the additives increased the electrical impedance of the electrode. Through a response optimization process, we found an optimum composition range of additives to exhibit the greatest discharge capacity of the electrode.
