This SAE RP provides a set of test methods and practices for the characterization of the properties of lithium battery anode active materials. Lithium battery anode active materials can be grouped in one of the following categories: lithium intercalation materials (including graphite, Li4Ti5O12); lithium alloying materials (including Sn, Si compounds/composites); lithium deposition materials (lithium metal). For the purposes of this document, material properties will be examined for particulate anode active materials (graphite, Li4TiO5, Sn compounds, Si compounds) and for metallic films (lithium metal). It is not within the scope of this document to establish criteria for the test results, as this is usually established between the vendor and customer It is not within the scope of this document to examine the electrochemical properties of anode materials since these are influenced by electrode design.

This SAE Recommended Practice provides a set of test methods and practices for the characterization of lithium ion battery cathode active material. It is beyond the scope of this document to establish criteria for the test results, as these are usually established between the vendor and customer. It should be noted that materials properties can vary substantially between classes of materials (e.g., LNO and LFP) and caution should be exercised when attempting to directly compare their chemical and physical properties. While these distinctions are important for the manufacturer, this document focuses on the techniques to measure the materials properties and not their absolute or relative values. Future materials such as solid-state batteries and sulfides are beyond the scope of this document.
