AnteoTech has announced a major performance milestone for its Ultranode™ high-silicon anode technology.
The company confirmed that its 70% silicon Ultranode X anode has achieved 890 cycles with 80% capacity retention, alongside 1,070 cycles at 70% capacity.
Ultranode is designed to deliver over 30% higher energy density compared with conventional graphite anodes. This translates into extended EV driving ranges – from 500km to 650km using the same battery pack size – and the potential for smaller, lighter batteries in consumer and medical applications.
AnteoTech’s portfolio includes three tailored configurations:
- Ultranode 95, optimised for high energy but lower cycle-life, suited to unmanned aerial systems and drones in defence applications.
- Ultranode 70, balancing energy density and cycle-life for 3C applications such as mobile phones, wearables and e-mobility.
- Ultranode X, targeting EVs with maximised cycle-life, delivering >90% first cycle efficiency and coating capacities between 900–1,100mAh/g.
Following intensive evaluation with Mercedes-Benz, AnteoTech has gained deep insight into EV anode requirements. This knowledge is now being applied across the sector, with OEMs seeking lighter batteries and improved ranges. The company is also collaborating with Wyon on medical device batteries.
Merrill Gray, AnteoTech’s managing director and CEO, said, “Achieving this cycle-life and performance milestone, of nearly 900 cycles at 80% capacity retention, with 70% silicon content with our Ultranode technology is another step forward for the company.”
