Originally battery accessories are experimental devices designed specifically for electrochemical testing, mainly used for in-situ characterization of battery materials during charging and discharging processes, commonly found in X-ray diffraction (XRD).
1. Core functions and application scenarios of originally battery accessories
(1)Originally testing:
Real time monitoring of material phase structure changes (such as crystal structure and phase transition) during battery charging and discharging can avoid sample contamination or state changes caused by battery disassembly. Support multiple electrochemical systems, including composites containing carbon, oxygen, nitrogen, sulfur, metal embedment, etc.
(2) Multimodal compatibility:
X-ray diffraction (XRD): used to analyze the structural evolution of positive/negative electrode materials during charge and discharge processes.
2. Structural composition and technical characteristics of originally battery accessories
(1) Key components:
Lower insulation cover: usually made of alumina ceramic or polytetrafluoroethylene material, containing coolant flow channels or resistance wire installation pipelines, used for temperature control.
Upper conductive cover: connected to the lower insulating cover by bolts to form a closed space, with a beryllium window (diameter 15mm, thickness 0.1mm) at the top to transmit X-rays.
Electrode system: originally battery accessories includes a lower electrode (with a support column) and a butterfly spring, which are electrically connected through compression fixation, simplifying the assembly process.
(2) Technological innovation:
Formal design: Compared with the traditional inverted method, the formal structure does not require flipping assembly, making it easy to operate in the glove box and ensuring the flatness of the beryllium window and diaphragm.
Sealing and temperature control: Integrated coolant circulation pipeline and resistance wire heating device, suitable for a temperature range of -400 ℃ to 400 ℃.
3. Technical advantages of originally battery accessories
(1) Simplified operation:
Reduce assembly steps, decrease operating time inside glove boxes, and improve efficiency. The butterfly spring fixes the electrode without the need for rotation and tightening, avoiding interference with the simulated structure of the battery.
(2) Performance improvement:
The high X-ray transmittance (>90%) of beryllium windows ensures the detection signal strength.
The multifunctional sample stage supports automatic sample changing and is suitable for high-throughput testing.
Overall, originally battery accessoriesare important tools for electrochemical research, as their design optimizes the assembly process of traditional battery simulation structures and enhances the reliability and applicability of originally testing.
