Introduction
Interpretation of activated carbon standards for supercapacitors
| Classification and grade comparison table of activated carbon for supercapacitors | ||||
|---|---|---|---|---|
| Type | Grade | Specific surface area/(m²/g) | First discharge specific capacitance/(F/g) | Applicable fields |
| Activated carbon (AC) | I | M≥2000 | Organic system: ≥65.0 | High energy supercapacitor |
| II | ≥1500 | Inorganic system: ≥55.0 | Industrial energy storage system | |
| III | ≥1000 | Mixed system: ≥37.5 | Consumer electronic devices | |
Technical requirements for activated carbon for supercapacitors
Case study: Practical application of different grades of activated carbon
Taking the data in Table 1 as an example, we can see that:
- Grade I activated carbon is suitable for application scenarios with extremely high energy density requirements, such as high-end consumer electronic devices and electric vehicles.
- Grade II performs well in the field of industrial energy storage and is suitable for large-scale energy storage systems that require stable electrochemical performance.
- Grade III is widely used in general supercapacitor manufacturing due to its low cost.
Standard Development Background and Technology Evolution Analysis
With the increasing global demand for green energy and efficient energy storage technology, supercapacitors, as a new type of energy storage device, have received widespread attention in recent years. The formulation of the GB/T 37386—2019 standard aims to standardize the quality and technical requirements of activated carbon for supercapacitors to ensure its performance and safety in practical applications.
From the perspective of technological evolution, activated carbon for supercapacitors has undergone a transformation from traditional carbon materials to high-performance porous carbon materials. In recent years, with the advancement of nanotechnology and synthesis methods, the specific surface area, pore structure and electrochemical properties of activated carbon have been significantly improved.
Implementation recommendations
To ensure that the quality of activated carbon for supercapacitors complies with the GB/T 37386-2019 standard, the following measures are recommended:
- Strict sampling procedures: Sample collection and testing are carried out in accordance with standard requirements to ensure batch consistency.
- Establish a quality control system: Implement full-process quality monitoring from raw material screening to finished product testing.
- Strengthen technical training: Train relevant personnel on standardized operations and testing methods.
- Regular re-inspection: For product batches that have been suspended for a long time and resume work, a comprehensive re-inspection should be carried out.
