As their name, these batteries designate for one time usage

Advantages & Disadvantages of these type of batteries:

  • High energy density. Can reach 700Wh/Kg
  • Can operate or be stored for years (usually 5-10 years)
  • Lower self-discharge
  • No charging + less control electronics = simpler solution
  • In proper design, can be easily replaced in the field.
  • Low current (low C-rate) only. Even high current types are considered low in comparison to rechargeable batteries.
  • Less environment friendly than rechargeable batteries.
  • More problematic to transport
  • For large batteries – usually not cost effective.

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 puls

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.
