PRIMARY BATTERIES

 

As their name, these batteries designate for one time usage

Advantages & Disadvantages of these type of batteries:

Advantages

Disadvantages

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:

 

Amicell conducted several projects using these type of cells.  Usually – aerial applications & sealed equipment. 

Even in a COTS product, like Lithium cells, there is a difference between different brands and different cell size.  Amicell uses a variety of brands, from which we consider to use in a given application.  We also hold and use the equipment needed for the test of the assembly in order to verify its long life.
