Lithium-Based Batteries – What Every Manufacturer Should Know (Part 2)

01 December 2011

Last week, this blog explored common factors that manufacturers should be aware of from a safety standpoint when using lithium batteries. Today, this blog will take a closer look at the common external causes of battery faults.

Some of the most common causes of battery faults originating from the user or application include:

  1. External short circuit of the battery
  2. Excessive discharge or charge current
  3. Pole reversal, i.e. discharge of a cell below 0V
  4. Charging primary batteries
  5. Incorrect or insufficient charge control of chargeable batteries

All five of these conditions generate heat to a varying extent in the battery cell, which leads to increased aging or breakdown of the cell. As these risks are caused by external factors, it is possible to prevent and avoid them.
