一、Core functions and application scenarios of originally battery accessories

Functional positioning of originally battery accessories:

1.Implement real-time testing during battery charging and discharging processes (such as XRD, optical observation, etc.) to avoid data loss or sample contamination caused by traditional disassembly.

2.Simulate the working environment of real batteries, support temperature control, electrolyte addition, and sealing guarantee.

Typical application scenarios of originally battery accessories:

1.XRD in-situ testing: Analyze the crystal phase changes of electrode materials (such as LiFePO4) during charge and discharge processes.

2.Optical in-situ observation: Observe the surface reaction of the electrode through a beryllium window (polyester film).

3.High throughput screening: supports battery performance research under multiple conditions (temperature, pressure, electrolyte).

4.Widely used in electrochemical systems containing carbon, oxygen, nitrogen sulfur, metal embedded complexes, etc.   

二、Structural composition and material properties of originally battery accessories

1.Core components of originally battery accessories:

Lower insulation cover: mostly made of alumina ceramic or polytetrafluoroethylene material, including installation chamber and coolant flow channel, supporting temperature control.

Upper conductive cover: designed with through holes, bolted to the lower insulating cover to form a current path.

Lower electrode: including top plate and support column, fixed by butterfly spring compression, simplifying the assembly process.

Beryllium window (polyester film): diameter 15mm (customizable), thickness 0.1mm (customizable), used for X-ray penetration or optical observation.

2.Technical improvement of originally battery accessories:

Formal assembly: replaces traditional inverted methods, simplifies the operation process, and reduces the impact of compression on the separator and positive electrode materials.

Cooling and Heating: The lower insulation cover integrates a coolant channel or resistance wire pipeline, supporting temperature control of -400℃.

Sealing design: The butterfly spring compresses and fixes the lower electrode, and cooperates with the installation seat airflow to blow and prevent frost and ice formation.

三、Technical advantages of originally battery accessories

1. Convenient operation of originally battery accessories:

The formal structure reduces the operating time inside the glove box and lowers the assembly complexity.

Modular design of components (such as replaceable beryllium windows and insulation sleeves) improves maintenance efficiency.

2. Performance parameters:

Test range: Temperature range of 0.5-160℃, temperature resistance up to 400 ℃.

Sealing: Supports long-term stable storage of electrolyte to avoid leakage.

Compatibility: Suitable for X-ray diffractometers and other equipment.
