Introduction

Li-ion batteries are currently being developed in many shapes and sizes. A variety of chemistries are being pioneered and new types are being developed. The safety issue that exists is well known and a major part of this development effort is to get a chemistry that gives good thermal stability under conditions of abuse and normal use. Several test methods have been used but the Accelerating Rate Calorimeter has become recognised as a technique that can quantify their hazard potential.

THT ARC

At Thermal Hazard Technology we have developed an Accelerating Rate Calorimeter and have modified this to be of specific use for battery testing. This instrument is now commercially available – and a testing service is available. This technology is introduced here and examples show how it is used to gain safety information on Li-ion batteries.
