Today the most popular type of batteries for industrial applications are NiCd batteries, which outperform lead acid batteries in many ways. Compared to a lead acid battery, maintaining a NiCd Battery is much easier and its lifespan is much longer, which means less maintenance.
Nickel cadmium batteries can be divided into 3 types:
► L Series: Low intensity discharge batteries.
► M Series: Medium intensity discharge batteries.
► H Series: High intensity discharge batteries.
DESIGN - STRUCTURE
Ni-Cd batteries consist of two groups of plates with the same structure, the positive plate contains nickel hydroxide and graphite, while the negative plate contains cadmium hydroxide.
These active materials are placed in a perforated polypropylene container with posts mechanically attached to form a rectangular plate.
► PLATES: Plate components do not wear out from repetitive charge and discharge cycles, giving batteries a longer and more efficient lifespan. Compared to alkaline electrolyte batteries, battery components do not react with Steel, which means that the structure of the plates should not be changed throughout their lifetime.
► SEPARATORS: The separators are made from plastic materials, which separate the plates and isolate the frames of the plates between them. This gives the electrolyte greater circulation within the cells and better gas dissipation.
► ELECTROLYTE: The electrolyte used in NiCd batteries is a caustic potash solution, providing high performance, long lifespan and high performance. The concentration of the electrolyte allows the battery a temperature ranging from -50°C ~ 70°C with decreased efficiency, the recommended temperature range for battery operation is 20°C ~ 40°C.
► TERMINALS: Terminals are made from nickel plated steel bars with high conductivity and performance. The cell cover and terminals are sealed by pressure, which ensures a good seal throughout the battery lifetime.
