8. Validating Next-Gen Batteries: Word-leading Lithium Battery Testing Solutions Provider –IEST Instrument

To validate the extreme performance, thermal stability, and cycle life of next-generation cells like the BYD Blade 2.0, high-precision laboratory testing is essential. As a pioneer in lithium-ion battery testing and a testing equipment supplier for BYD, IEST Instrument is dedicated to delivering efficient and cutting-edge testing solutions for global electrochemical energy storage, empowering clients to achieve R&D breakthroughs and quality enhancement. The company’s core team comprises seasoned experts in materials science, electrochemistry, and automation, backed by over 100 authorized patents. Its testing equipment has been widely adopted in power batteries, energy storage systems, and materials science research, serving clients across more than 20 countries and regions, serving over 1200 customers globally. For engineers developing or evaluating high-energy-density LFP cells, IEST Instrument provides the critical measurement tools required for commercial success.

• Powder Resistivity & Compaction Density Measurement System (PRCD3100)
  Advancing energy density in LFP cells requires precise characterization of cathode and anode powders at the material stage. The PRCD3100 measures powder resistivity and compaction density simultaneously under pressures up to 350 MPa, with a resistance range up to 200 MΩ. Freely switchable two-probe and four-probe modes support both R&D formulation screening and batch-to-batch production consistency monitoring for LCO, NCM, LFP, graphite, solid electrolyte powders, and conductive agents.

• Electrode Sheet Resistance Tester (BER2500)
  Reducing internal resistance at the electrode level — a key factor in high-rate LFP performance — requires accurate through-thickness resistance data from practical electrode samples. The BER2500 uses a double-sided controllable pressure disc electrode method to directly measure coating resistance, coating–current collector contact resistance, and current collector resistance in a single test. Separate voltage and current terminals eliminate inductive interference, making it suitable for both electrode formulation development and process stability monitoring.

• In-Situ Cell Swelling Testing System (SWE Series)
  Understanding mechanical deformation during cycling is critical for validating the structural integrity of blade-format and prismatic LFP cells. The SWE Series measures swelling thickness and expansion force in real time throughout charge–discharge cycles, supporting electrode-level through full-cell testing across coin cell, pouch, prismatic, and short-blade formats. Force ranges span 5 kg to 10,000 kg; temperature control covers −20°C to 80°C. The system also supports non-destructive in-situ lithium plating detection — directly relevant to fast-charging validation at 3C and above.

• In-Situ Battery Gassing Volume Analyzer (GVM2200)
  Safety validation for high-energy-density LFP cells requires quantitative data on gas evolution across formation, cycling, overcharge, and storage conditions. The GVM2200 records cell volume changes in situ throughout the full charge–discharge process with 1 µL resolution, simultaneously capturing gassing volume, pressure, and rate at each stage. Multi-channel configurations (up to 8 channels) and temperature control from room temperature to 85°C support both R&D screening and accelerated aging studies.
