In the field of battery testing, most data errors never stem from the samples themselves, but from minor omissions in the testing process: Open-loop testing is susceptible to interference from ambient light, airflow, and dust; the electrode clamps have uneven force application and the contact surfaces oxidize and leak electricity; the four-wire testing has cumbersome wiring and large alignment deviations; multiple re-tests result in significant data dispersion, greatly affecting the experimental conclusion and the progress of research and development. For battery research, teaching experiments, sample calibration, and performance testing, a set of sealed, stable, standardized, and low-interference testing fixtures is the core key for accurately collecting data and ensuring the repeatability of experiments.

The fully sealed protective structure isolates external interference, making the testing environment more controllable.

Standardized precise clamping, with uniform force application, eliminates false connections and drifts.

The clamping force is gentle and controllable, which can firmly fix the samples, preventing displacement, shaking, and drift during the test, while not compressing and damaging the battery electrodes, films, and functional layers, completely preserving the original state of the samples, effectively improving the consistency and repeatability of the experiments, and making the hardware variables of each test completely unified.

For high-precision electrochemical testing of batteries, the equipment is equipped with dual standard BNC interfaces, perfectly adapting to the four-wire testing scheme, precisely separating the current and voltage testing circuits, completely avoiding test deviations caused by wire resistance and contact resistance, significantly improving the test accuracy of core parameters such as internal resistance, open-circuit voltage, short-circuit current, and conversion efficiency.

Highly precise and durable to operate, suitable for high-frequency scientific research testing scenarios.

At the same time, relying on 3M's mature materials and structural processes, the equipment is compatible with various battery testing systems, source meters, and photovoltaic performance testers, with convenient wiring, full adaptability, and the ability to quickly build a standardized testing platform, suitable for university teaching training, research institutes' photovoltaic research and development, and enterprise battery quality inspection in all scenarios.

It is widely compatible with the electro-optical performance testing, electrochemical parameter calibration, aging performance monitoring, teaching experiment demonstrations, and research project development of various samples such as dye-sensitized batteries, solar cell wafers, thin-film batteries, and micro-energy storage cells. It can not only meet the routine testing needs of basic teaching but also support high-precision scientific data output, and is a standard precision equipment for battery testing laboratories.

With 3M's precise technology, it isolates interference, stabilizes data, and simplifies operations. One 3M sealed battery fixture eliminates ineffective re-tests and data deviations, making each set of experimental data precise, controllable, and true, efficiently helping battery research and testing to improve efficiency and effectiveness!
