Purpose of This Note: This application note discusses electrochemical measurements on lithium ion batteries. Theory and general setup of lithium ion batteries are explained. Important parameters for characterizing batteries are described. In addition, various experiments on coin cells are performed.
Purpose of This Note This application note discusses the differences between 2‑point and 4‑point measurements of batteries. These two typical setups are compared with Gamry’s battery holders for CR2032 coin cells and cylindrical 18650 batteries. Both holders allow direct‑contact Kelvin
