ABSTRACT Black phosphorus (BP) is a layered and two‐dimensional substance that has been discussed as an anode material for lithium‐ion batteries (LIBs) due to its exceptionally large theoretical capacity, anisotropic electrochemical characteristics, and bandgap control. However, pristine BP suffers from problems such as significant volume expansion, capacity fading, and low coulombic efficiency. To overcome these challenges, researchers have explored BP incorporated with various nanocomposites to not only improve structural stability and conductivity of BP, but also suppress its environmental degradation and optimize its electrochemical performance. This review focuses on modification strategies such as carbon‐based hybridization, metal doping, and heterostructure engineering to address these challenges. It also systematically compares the strategy of synthesis of the BP‐based nanocomposites, such as high‐energy ball milling machine, chemical vapor deposition, liquid exfoliation, and their combination with various reinforcements. The electrochemical behavior of these composites, such as specific capacities, rate capability, cycling stability, among others are evaluated and compared, and the results are summarized in a tabular form to make them clear. In addition, this review explains how the BP‐based nanocomposites can be used to transform the LIB technology while identifying key research directions to advance the versatility of these composites in real‐world applications.
