Security

We implement thorough room access control based on ID cards and surveillance cameras. Moreover, we store customers’ precious test data in systems that are entirely isolated from external networks.

Thorough Confidentiality

We maintain strict confidentiality with all Battery Testing Service contents including information and test data disclosed by the customers. When necessary, we sign NDA (non-disclosure agreements).

Scope of Liability and Compensation

Damages to samples arising from equipment failures, power interruptions and so on are not included in the scope of compensation.
We refuse to undertake testing on samples for which damage is not an option.
Confidentiality: we do not disclose to third parties.
Guarantee for test findings: test results are obtained from this system, but we cannot guarantee results under different conditions.

Analysis

We provide a wide range of services including battery disassembly investigations, defect analysis, component analysis, etc. (Qualitative/quantitative analysis of generated gases, X-ray CT observation before and after vibration testing, etc.)
Please feel free to discuss regarding battery disassembly investigations and defect analysis.

X-ray CT System

This system can observe the inner workings of batteries in a nondestructive manner. It can easily conduct comparisons before and after vibration tests, etc.

Observation example (X-ray CT system: inner structure of battery)

Scanning Electron Microscope

We can create element maps through EDX analysis. We also have a fully equipped ion milling system capable of performing unstressed processing.

Observation examples (SEM/EDX-LIB cathode surface)

Gas Chromatograph Mass Analyzer

This can perform component identification/weighing on electrolytic solution solvents, added components, and gases that are generated in safety testing.
