What is a RoHS Battery Certification? RoHS (Restriction of Hazardous Substances) certification ensures electronic products’ safety and environmental friendliness. This article delves into the significance of RoHS battery certification and its impact on product safety and compliance.
Part 1. What is a RoHS Battery Certification?
A RoHS battery certification is a validation that a battery complies with the RoHS directive, which restricts the use of certain hazardous substances in electrical and electronic equipment. This certification ensures that the battery does not contain substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs) beyond specific thresholds. It confirms that the battery is environmentally friendly and safe for various electronic devices.
RoHS Certification Restricted Materials:
The RoHS directive prohibits using several substances in electrical and electronic equipment. These restricted substances include:
- Lead (Pb): < 1000 ppm
- Mercury (Hg): < 100 ppm
- Cadmium (Cd): < 100 ppm
- Hexavalent Chromium (CrVI): < 1000 ppm
- Polybrominated Biphenyls (PBB): < 1000 ppm
- Polybrominated Diphenyl Ethers (PBDE): < 1000 ppm
- Bis(2-Ethylhexyl) phthalate (DEHP): < 1000 ppm
- Benzyl butyl phthalate (BBP): < 1000 ppm
- Dibutyl phthalate (DBP): < 1000 ppm
- Diisobutyl phthalate (DIBP): < 1000 ppm

Part 3. The battery’s process for acquiring RoHS certification
3.1 Sample Collection and Preparation
Collection
We collect samples of battery components from the production line or storage area. These samples represent the materials used in battery manufacturing.
Preparation
We prepare the collected samples for testing by grinding, milling, or using other suitable methods to ensure homogeneity. This step ensures that the test results accurately reflect the composition of the battery components.
3.2 Chemical Analysis for Restricted Substances
Testing Procedures
The prepared samples undergo chemical analysis to detect the presence of restricted substances such as lead, cadmium, mercury, and others.
Acid Digestion
The samples may be subjected to acid digestion and treated with acids to dissolve the materials and release the target elements for analysis.
Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
We use ICP-MS to quantify the concentration of restricted substances in the sample. This technique provides susceptible and accurate measurements of trace elements.
3.3 X-Ray Fluorescence (XRF) Spectroscopy
Principle
XRF spectroscopy is employed to analyze the elemental composition of the sample. Bombarding the sample with X-rays emits characteristic fluorescent X-rays, which we analyze to determine the presence of specific elements.
Instrumentation
A specialized XRF spectrometer is used for this analysis and can detect and quantify the elements present in the sample.
3.4 Atomic Absorption Spectroscopy (AAS)
Procedure
AAS is another method employed for elemental analysis. It involves measuring light absorption by the atoms of the target elements in the sample.
Atomization
The sample is atomized, typically through flame or furnace methods, to convert the elements into free atoms for analysis.
3.5 Documentation and Reporting
Results Compilation
The results of the chemical analysis are compiled, detailing the concentrations of restricted substances in the sample.
Compliance Assessment
Based on the test results, the battery components’ compliance with RoHS regulations is determined.
Reporting
A comprehensive report is generated, documenting the testing process, results, and compliance status. This report serves as official documentation for RoHS certification.

Part 6. FAQs
-
What is a RoHS battery?
A RoHS battery complies with the Restriction of Hazardous Substances (RoHS) directive, which restricts using certain hazardous materials in electrical and electronic products. -
Is RoHS certification the same as CE?
No, RoHS certification focuses on restricting hazardous substances, while CE certification indicates conformity with health, safety, and environmental protection standards. -
Are RoHS and REACH the same?
No, RoHS restricts hazardous substances in electrical and electronic equipment. At the same time, REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) regulates the production and use of chemical substances in the European Union. -
Is RoHS certification required?
Yes, RoHS certification is required for products sold in the European Union to ensure compliance with environmental regulations and the restriction of hazardous substances. -
How long is a RoHS certificate valid for?
The RoHS certificate is typically valid for five years, although the specific duration may vary depending on regulatory changes and factors such as product composition. As a result, renew or update the RoHS certificate to reflect changes in compliance status.
