LAMne describes the degradation or consumption of the active material within the anode of a battery. For many lithium-ion batteries, graphite is the primary active material in the anode. Its layered structure allows for the intercalation of lithium ions. The loss of active anode material directly impacts the battery's capacity and overall cycle life. As the graphite is consumed, the battery's ability to store energy diminishes, leading to a decrease in its overall performance and efficiency.
