Hard Carbon Anode Materials, often referred to as 'non-graphitizable carbon,' are a unique category of carbon materials that resist transformation into graphite even at temperatures exceeding 3000°C. These materials are composed of disordered, twisted graphene sheets with an interlayer spacing ranging from 0.37 to 0.40 nanometers - significantly larger than graphite’s 0.335 nanometers. This structural feature makes hard carbon particularly adept at storing larger ions, such as sodium, offering superior storage capacity compared to graphite in certain applications. Hard carbon finds its primary use in energy storage technologies, including lithium-ion batteries, lithium-ion capacitors, and sodium-ion batteries.
Historically, Sony employed hard carbon derived from polyfurfuryl alcohol resin in the first commercial lithium-ion battery in 1991, leveraging its higher specific capacity and electrolyte compatibility with ether-based systems. However, the advent of carbonate electrolytes shifted preference to graphite, though hard carbon retains advantages in specific niches. Its high surface area makes it an ideal anode material for supercapacitors, while its compatibility with sodium ions positions it as a frontrunner for sodium-ion battery development.
Key benefits of hard carbon anodes include enhanced structural stability, extended charge-discharge cycle life, improved safety, and superior performance in low-temperature environments due to easier lithium-ion diffusion, avoiding issues like lithium dendrite formation seen in graphite. However, drawbacks include lower initial coulombic efficiency, reduced lithium storage capacity, and overall lower energy density.
These characteristics make hard carbon suitable for applications requiring high instantaneous power, such as vehicle stop-start systems, as well as low-temperature and power batteries. The material’s precursors vary widely, encompassing bio-based polymers like bamboo, coconut shells, starch, and walnut shells, alongside chemical sources such as anthracite, pitch, and phenolic resin, leading to significant performance and cost variations depending on the raw material used.
