As their name, these batteries designate for one time usage

Advantages & Disadvantages of these type of batteries:



High energy density.  Can reach 700Wh/Kg

Low current (low C-rate) only.  Even high current types are considered low in comparison to rechargeable batteries.

Can operate or be stored for years (usually 5-10 years).

Less environment friendly than rechargeable batteries.

Lower self-discharge

More problematic to transport

No charging + less control electronics = simpler solution

For large batteries – usually not cost effective.

In proper design, can be easily replaced in the field.


The leading technologies of this field of the primary batteries are Alkaline and Lithium under several types:

  • Lithium-Thionyl chloride (Li-SOCl2) – Bobbin

Basic features

  • High energy density ~650Wh/Kg
  • Low discharge power ~0.05C pulse
  • Lithium-Thionyl chloride (Li-SOCl2) – Spiral

Basic features

  • Lower energy density ~400Wh/Kg
  • Higher discharge power ~0.3C pulse
  • Lithium Manganese Dioxide (LiMnO2)
  • Lithium Sulfur Dioxide (LiSO2)

Amicell conducted several projects using these type of cells.  Usually – aerial applications & sealed equipment.  There is a large variety of brands & manufactures with different quality & cell dimensions, from which Amicell chooses the brands most fit the customer.  Our tests of these type of cells include short performance tests, FAI tests and long life tests
