Lithium Secondary - Rechargeable


Lithium Ion: Lithium ion batteries use lithium metallic oxide in its positive electrode (cathode) and carbon material in its negative electrode (anode). Lithium ions inside the battery transfer between the positive electrode and the negative electrode during charge or discharge.

Features:


  • high operating voltage of 3.6 to 3.7 volts, reducing the number of cells required
  • high energy density with low weight
  • no memory effect
  • overcharge and over-discharge circuit protection required

Lithium Polymer: Lithium polymer batteries use a gel-type electrolyte to provide power. Battery components are solid, eliminating the need to contain liquid electrolyte. This allows for smaller cell configurations.

Features:


  • high operating voltage of 3.6 to 3.8 volts, reducing the number of cells required
  • high energy density with low weight
  • no memory effect
  • overcharge and over-discharge circuit protection required
