The type segmentation of MCMBs distinguishes products by morphology, purity level, and surface treatment, each influencing end‑use suitability and price premium. Spherical MCMBs, characterized by a uniform diameter (typically 5–15 µm), dominate the market due to their predictable packing density and ease of slurry formulation; they underpin most battery‑grade supplies. Irregular MCMBs, with broader size distribution, are confined to lower‑cost applications such as conductive fillers. Coated MCMBs, where a thin graphitic or polymer layer is applied, command higher margins because the coating mitigates side‑reaction and enhances electrode stability, especially in high‑voltage cells. Within these families, sub‑types such as high‑purity (≤ 0.5 % ash) and low‑impurity (≤ 1 % ash) variants determine electrochemical performance and are priced accordingly. Nano‑structured MCMBs, featuring sub‑micron primary particles, are a niche but rapidly growing segment for advanced supercapacitor electrodes, reflecting a shift toward higher energy density solutions. Together, these type categories allocate production capacity and R&D resources, directly affecting the market’s total addressable volume.
