1.3 Electrode Frame
The electrode frame consists of a right and a left side bar as well as the electrode edge
which are connected by welding, giving shape to the electrode frame. The electrode frame
operates as a current collector and also seals the electrode plates. This procedure leads to
an electrode design with high mechanical robustness but also ensures a reliable service for
the complete lifetime of the battery.
1.4 Positive and negative electrode plate
The nickel-cadmium cell is composed of the positive plates containing nickel hydroxide and
the negative plates containing cadmium hydroxide.
Individual pockets are formed from a nickel plated and perforated steel tape (pocket tape)
and house strips of the active material.

1.2 Safety terminal
Tha Alpha Lomain battery features a specially developed terminal design with a redundant
leak protection to prevent electrolyte leakage. The battery terminals may be either male
of female threaded, depending upon the type and range of the battery. In either case, the
polarity of the terminals will be clearly indicated (color-coded).
