Biography
Hello, I am Tianlu Pang.
I hold a Master’s degree in Materials and Chemical Engineering. My research is primarily based at the Shanghai Institute of Microsystem and Information Technology (SIMIT), Chinese Academy of Sciences (CAS) and the Shanghai Synchrotron Radiation Facility (SSRF) beamline BL02B, focusing on all-solid-state battery interface engineering and advanced in-situ soft X-ray spectroscopy.

Core Research Thrusts
1. Room-Temperature Ultrasonic Welding of Solid-State Battery Interfaces
To overcome the severe solid-solid contact impedance and dendrite propagation between LiMg alloy anodes and garnet-type LLZTO solid electrolytes, we developed a room-temperature ultrasonic welding technique. The transient high-frequency mechanical vibration effectively breaks through surface passivating Li₂CO₃ layers, achieving an ultra-low interfacial area-specific resistance of 65 Ω cm², a critical current density of 4.45 mA cm⁻², and stable symmetric cell cycling exceeding 1000 h. UW-LiMg/LLZO/LFP full cells achieved 153 mAh g⁻¹ at 0.5 C with > 90% capacity retention over 200 cycles.
- Featured Publication: First author in Advanced Science (2025, IF 14.1, DOI: 10.1002/advs.202410865).
2. In-situ Soft X-ray Absorption Spectroscopy (sXAS) Cell for Batteries
Designed and engineered the first vacuum-compatible in-situ cell holder, piezoelectric chopper, and inert-atmosphere transfer system tailored to the geometry and UHV conditions of SSRF BL02B. Utilizing Mg K-edge XANES / EXAFS and O K-edge TEY spectroscopy, we directly observed selective Mg oxidation and the in-situ construction of a nanoscale MgO buffer layer during electrochemical cycling.
- Intellectual Property: Patent filed and currently under substantive examination.
3. Near-Ambient-Pressure XPS (APXPS) & Atmosphere Degradation
Investigated interfacial degradation mechanisms between novel oxyhalide solid electrolytes (LiAlOCl) and high-Ni cathode materials under controlled CO₂ and H₂O partial pressures using APXPS, Auger electron yield (AEY), and in-situ XRD at BL02B01, establishing experimental guidelines for dry-room standards in industrial manufacturing.
4. AI for Science & Automated Spectral Processing
Developing Python data pipelines for batch normalization, baseline correction, and EXAFS fitting of beamline raw spectra; combining the Materials Project database with machine learning models to screen phase stability and interfacial compatibility of novel solid electrolytes.
About This Blog
During sleepless night shifts on the synchrotron beamline, I often observed that synchrotron spectroscopy and advanced characterization tools present steep conceptual barriers for researchers specializing in materials synthesis and battery cell engineering.
PANG Blog is my public research notebook. My goal is to translate microscopic synchrotron data into intuitive, physically grounded understanding of why battery interfaces work—and why they fail.
