Description

Description générale

Mesocarbon microbeads (MCMB) are a form of synthetic graphite, produced from petroleum pitch or coal tar. These materials are characterized by their distinct bead-like morphology and are categorized under "soft" carbons due to their graphitization onset at temperatures above 2000 °C. Our MCMB is synthesized to achieve a small average particle size of ~11 microns and low surface area (~1.5 m2/g).

Application

As a carbon anode material for lithium-ion batteries, MCMB exhibits several advantageous properties. It boasts a high specific capacity and its spherical morphology contributes to an increased packing density within the anode structure. The minimized surface area of MCMB plays a pivotal role in reducing detrimental side reactions throughout the charge-discharge cycles, curtailing irreversible capacity losses commonly attributed to solid-electrolyte interphase (SEI) layer formation. While MCMB has garnered recognition as an optimal anode constituent in various energy storage applications—including lithium-ion batteries, lithium-ion supercapacitors, Li-S batteries, and MCMB–Si composite batteries—it is generally deemed unsuitable for sodium-ion battery technology.
