FRX, FRM Batteries
Nickel Cadmium Fibre Positive and Pasted Negative Batteries
HBL Nickel cadmium FRM, FRX series are constructed using Fibre positive and Pasted negative electrodes.
Nickel cadmium FRM, FRX series are constructed using Fibre positive and Pasted negative electrodes.
Nickel Cadmium Fibre electrode batteries may be seen as 3rd generation (1980’s) technology. Pocket plate is 1st generation (1919) and Sintered Plate is 2nd generation (1950’s). The Fibre Electrode Technology has been provided by DAUG, Germany (research venture of Mercedes Benz & Volkswagen).
The Nickel Fibre matrix used for the fibre plate allows 90% of the electrode volume for holding the active material. The open three dimensional fibre structure also provides good conductivity to ensure excellent electrical performance.
Nickel Cadmium Fibre plate technology uses active material free from graphite and iron. Elimination of these elements ensures that the electrolyte does not get carbonated and reduces water consumption.
The elastic nature of NCFP electrode enables it to absorb greater shock and vibration stresses. This includes volume changes during charge and discharge cycles, hence the battery can give more number of cycles compared to other battery technologies. The NCFP technology is considerably lighter in weight and hence has high energy density.
The pasted negative electrode are designed with high power density and has less water consumption, thus reduces the periodicity of topping –up the cells with DI water. The sintered micro-porous separators and membrane separators provide insulation between the plates and permits free flow of electrolyte.
These batteries are built in polypropylene containers to which lids are thermally welded to withstand impact resistance. This type of cells are translucent in nature, so electrolyte levels can be visualized. Flame retardant containers in the other hand are Opaque in nature, so the levels of electrolyte is not visible. If requested by the customer, flame retardant cells can be offered.,
Steel or Copper terminals and fasteners give these batteries the ruggedness required to meet the demanding application needs. Single cells are provided with reliable flame-arresting vents and are assembled in stainless steel crates for easy handling.
