Tianjing-BQ14's electrodes are made of solid titanium, one of the toughest yet human-friendly metals known. This provides the electrodes with longevity built to last at least 10 years. The titanium is coated with platinum for excellent, yet durable, conductivity. The combination of efficient draining, improved matting, and revised inner structure enable Tianjing-BQ14 to operate continuingly over for 100 hours.
