Impurities in electrode materials can hinder electrochemical reactions, reduce capacity and accelerate degradation. Testing of electrode materials helps ensure purity and consistency, leading to optimal battery performance. Almost all the components of the battery are isolated and tested individually.
Analytical testing of raw materials helps identify and control impurities to ensure consistent and high-quality battery production. Impurities in electrode materials can hinder electrochemical reactions, reduce capacity and accelerate degradation.
These specifications include but are not limited to safety, cycle life, cost, reusability and sustainability of the manufacturing process. Some areas where battery testing is essential are outlined below.
Raw materials are the starting point of the battery manufacturing process and hence the starting point of analytical testing. The main properties of interest include chemical composition, purity and physical properties of the materials such as lithium, cobalt, nickel, manganese, lead, graphite and various additives.
Battery performance testing - Post-production monitoring By immersing two different metals or metal compounds (electrodes) into an ion-conducting system (electrolyte), electrons tend to move from one electrode to the other, utilizing the basic electrochemical property of the electrodes.
The chemical purity of raw materials in battery production is of utmost importance to today’s materials engineers. Even the presence of small levels of unwanted contaminants may influence the characteristics of materials in terms of physical, electrical, or other properties; thereby, adversely affecting the reliability of the final product.
