Recently, GKINST Instruments' independently developed D-POWER X-Ray Diffractometer has successfully completed installation, commissioning, and full-performance calibration, and has been officially delivered and commissioned at BYD's laboratory. This delivery of D-POWER represents a significant breakthrough for domestically produced high-end XRD instruments in the new energy battery sector.
Independent R&D Breakthrough: Building a High-Penetration, High-Throughput, In-Situ Dynamic Characterization Platform
The delivered D-POWER XRD integrates a 3 kW high-power Mo-target X-ray source, parallel-beam focusing optics, a 2D area detector, and a cold-hot in-situ testing platform specifically designed for pouch cells — forming an advanced analytical system that combines high penetration, high throughput, and in-situ dynamic characterization capabilities.

Addressing the long-standing pain points of conventional XRD in encapsulated cell testing — "poor penetration, weak signal" — D-POWER employs a high-energy Mo target paired with parallel-beam focusing optics to deliver a high-intensity, high-collimation X-ray beam, enabling efficient penetration testing of pouch cells and complex encapsulated samples.
Application Value: Dynamically Tracking Battery Evolution, Supporting Material Performance Optimization
The system can dynamically track crystal structure evolution, phase transition behavior, and lattice parameter changes in pouch cells under charge-discharge cycling and varying temperature conditions, providing critical data support for research into capacity fade, cycle life, thermal stability, and failure mechanisms.

The figure above shows measured data from a pouch cell. The diffraction pattern clearly identifies the characteristic peaks of the LiCoO₂ cathode material, graphite anode, and copper and aluminum foil current collectors.
Meanwhile, the instrument is also applicable to structural analysis and performance optimization of new energy battery materials such as ternary cathode materials, effectively pressing the "accelerator" on the R&D and application of next-generation battery materials.
Sustained Value Delivery: Putting Equipment to Work, Letting Innovation Take Root
Delivery is not only the successful closure of a milestone — it is the starting point of a deeply connected innovation ecosystem. The true mission of D-POWER lies in providing BYD with a more precise "microscopic lens" for new energy material R&D, translating abstract microstructural characterization into tangible productivity that drives battery performance forward. Guoke Instruments will continue to leverage independent R&D as its core engine, deepening its roots in the new energy sector and helping China's new energy industry advance from scale-driven leadership to technology-driven depth leadership.
