3.7V Ultra Thin Lipo Battery Cells

DNK Power, with its R&D Team leaders Dr. Lee Hongshang from Tsinghua University, has been making ultra-thin lipo cells for more than 4 years. We can now offer ultra-thin film batteries of 2.0 mm to 0.5 mm thick with or without PCM. Although we don’t stock lipo cells in bulk, we have made more than 100 models during the past several years.

These cells should be used for smart cards, RFID tags, smart labels, miniature speakers, medical devices, military devices, tracking devices, portable sensors powered cards, wearables devices and other applications that require battery storage in a very thin battery (limited space).

See below main products our batteries have been applied.

  • Ultra High Energy Density
  • Low Self Discharge Rate. Less Than 2% Per Year.
  • Wide Operation Temperature. -20℃ ~+60℃
  • Ultra Thin Cell Thickness of  0.5-2 mm
0452039 30mah ultra thin lipo cell
