"High Energy Density Lithium Ion Batteries with Hetero-Hybrid Si/Ge-Carbon Nanotube Anodes"
– By Brian J. Landi, PhD, Rochester Institute of Technology
Combined benefits of LPCVD (low pressure chemical vapor deposition ) or PECVD (plasma enhanced chemical vapor deposition) Si with Ge nanoparticles and carbon nanotube has led to an ultra high capacity anode (>1000 mAh/g electrode), along with enhanced coulombic efficiency.
Full batteries incorporating properly matched hetero-hybrid anodes with conventional cathodes shows cell improvements in gravimetric energy density over state-of-the-art by more than 50%
Recent significant innovations within lithium-ion batteries have propelled the technology into a position in the marketplace far exceeding recent market survey results. Breakthroughs in new battery chemistries, novel electrode and electrolyte materials, system integration for a vast array of mobile and portable applications, from micro medical devices to high-energy/high-power automotive, have paved the roadmap for an emerging market with unlimited potential.
* New chemistries & materials to increase energy & decrease cost
