Hard Carbon-Coated Electrode

HCCE

Hard carbon-coated electrodes are advanced materials used in various types of batteries, including lithium-ion and sodium-ion batteries. These electrodes are engineered to enhance the performance, longevity, and efficiency of batteries. They are particularly valued for their high conductivity, stability, and ability to operate effectively at a wide range of temperatures.
