LAMpe describes the degradation or consumption of the active material within the cathode of a battery. Several materials are used as active cathode materials in lithium-ion batteries. Common examples include Lithium Cobalt Oxide (LCO), Lithium Iron Phosphate (LFP), and Lithium Nickel Manganese Cobalt Oxide (NMC). The loss of active cathode material results in reduced energy storage capacity of the battery. As these materials degrade, the overall energy density of the battery diminishes, leading to shorter usable battery life and decreased performance.
