Rechargeable alkaline manganese cell with cathode consistency compensation |
| abstract |
In an improved rechargeable alkaline manganese cell that has a manganese dioxide cathode comprising pellets formed by pressing a cathode powder blend comprising a hygroscopic additive for increasing cumulative capacity, the sticky consistency of the pellets, which is un-desirable for continuous automated production is compensated for by the addition of up to 0.5% of a hydrophobic binder. This small amount leaves the cell performance substantially unimpaired, but provides the desired consistency for large-scale production. Further disclosed is an improved charge methodology for a rechargeable alkaline manganese cell wherein the charge current is pulsed at a voltage in excess of 1.65 V and the no-load cell voltage response is monitored at predetermined intervals. No charge current pulse is permitted to pass through the cell if the no-load voltage exceeds a threshold value. This results in increased utilization of the capacity of the cell while reducing the likelihood of damage to the cell due to overcharging. |
