### Quality Control Systems

Great Power enforces 100% inline inspection at electrode coating, assembly, formation, and PACK integration stages. Full traceability links raw material lots to shipped system serial numbers.

#### MES-Integrated Production

Real-time data capture on every workstation; SPC alerts trigger line-stop before tolerance drift.

#### Automated Optical Inspection

Vision systems inspect weld integrity, tab alignment, and electrolyte fill levels at high throughput.

#### Environmental Stress Screening

Thermal cycling, vibration, and humidity chambers validate PACK assemblies against IEC 62619 and UL 1973 protocols.

#### Cell-to-Pack Traceability

QR-coded lot tracking links each finished system back to its source cathode batch, separator roll, and formation cycle log.

## R&D and Innovation

Great Power manufactures cell chemistry, pack architecture, and system integration in-house. The R&D program covers ion sponge technology, sodium-ion evaluation, and long-cycle LFP platforms.

### Ion Sponge Technology

Proprietary electrode structure absorbs mechanical stress during cycling. This reduces capacity fade and swelling while achieving energy efficiency exceeding 96%.

### Sodium-Ion Evaluation

Great Power was the first batch in China to pass sodium-ion battery evaluation by CETRI. Dedicated pilot lines test chemistries for stationary storage applications.

### Cycle Life Validation

Cell cycle life exceeds 10,000 cycles under standard conditions. Wide temperature capability from -30°C to 60°C supports charging across diverse deployment scenarios.

- **Validated Cycle Count:** 10,000+
- **Total Employees:** 10,000
