ULTRALIFE Thin Cell® has many advantages over traditional primary lithium coin cells:

ENERGY DENSITY

The energy density of ULTRALIFE Thin Cell® is around 500Wh/l and 400Wh/Kg compared to just 300Wh/l and 260Wh/kg for the best lithium coin cells. This high volumetric & gravimetric energy density means that devices can be made smaller & lighter – the requisite for wearable technology.

STORAGE

ULTRALIFE Thin Cell® retains >98% of its capacity after one year storage at room temperature & does not suffer from the passivation associated with other Lithium chemistries. This means they are always ready to use regardless of how customers choose to store their devices.

STABLE VOLTAGE

The Lithium Manganese Dioxide platform on which ULTRALIFE Thin Cell® is built provides a stable voltage to power electronic devices. With an operating voltage between 3.3V and 1.5V, the ULTRALIFE Thin Cell® is perfect for modern, low voltage electronic devices.

SLIM

ULTRALIFE Thin Cell® can be manufactured as thin as 1.1mm (0.043 inches) making them ideal for devices with a low profile such as ID tags & smart cards. Device designers can efficiently package the cells within their product as they do not expand or swell during storage or use.

RATE CAPABLE

The use of low resistance current collectors allows ULTRALIFE Thin Cell® to outperform coin cells at higher discharge rates – the ideal solution for applications which require high bursts of energy such as those with RF transmitters.

WIDE TEMPERATURE

ULTRALIFE Thin Cell® operates safely & effectively between -20°C & +60°C, making them suitable for a wide range of demanding applications. Their low temperature operation means they continue to operate when other batteries have frozen.

STANDARD & CUSTOM SIZES

In addition to off-the-shelf standard cell models, ULTRALIFE can specially manufacture Thin Cell® in unique sizes to suit specific customer requirements. Minimum order quantities start at 50k units with competitive tooling & qualification charges. Custom cell sizes can be accommodated within the following space envelope:

  • Length: 20mm to 305mm
  • Width: 20mm to 305mm
  • Thickness: 1.1mm to 6mm
