Description: High energy enviromental friendly Li-FeS2 Button Battery

  • Started developing in 2006, Heter’s iron button battery (1.5V Li-FeS2 button cell) was putting into the market in 2008. 
  • The 1.5V Li-FeS2 button cell was patented by SIPO in 2009. The patent numbers are     .
  • Customer ‘s feedback is very positive.


  • High capacity, up to 180mAh for FR1154. This capacity is higher than Ag-Zn/Zn-Mn cells.
  • Low self-discharge. Over 10 year shelf life at room temperature.
  • Wide temperature range
  • The working temperature range of Li-FeS2 button battery is -2060, while battery with anode of zinc deteriorate at a high temperature.
  • Light weight, 30% lighter than the weight of silver zinc and zinc-manganese battery.
  • Environment-friendly, RoHS compliant.
  • Plentiful raw materials compared with limited silver resource for Zn-Ag button battery, that made the mass production of Li-FeS2 button battery possible.
