This Small Business Innovative Research (SBIR) Phase II project proposes a prototype Lithium-ion battery that has inherent cost advantages for a NGV FreedomCar and hybrid electric vehicle, HEV, requiring compact pulse-power. The unique rolled-ribbon cell can meet the cost requirements and deliver thousands of pulses and recharges. The battery design projects power at 2-4kW/kg and power density at 7.5kW/liter similar to an ultracapacitor, with 20 times greater specific energy at 100- 120Wh/kg .The rolled-ribbon design is a technology that enables US producers to compete by lowering the materials requirement, packaging and safeguard costs of a large high-power battery. It fulfills the need for high power at low cost. In addition, this disc-shaped design exhibits excellent passive thermal management with inherent safety. Gasoline savings will reduce air pollution and oil imports.

该小型企业创新研究（SBIR）第二阶段项目提出了一种原型锂离子电池，该电池对于需要紧凑型脉冲电源的NGV FreedomCar和混合动力电动汽车HEV具有固有的成本优势。 独特的卷带电池可以满足成本要求，并提供数千个脉冲和充电。 该电池设计的功率为2-4kW/kg，功率密度为7.5kW/升，类似于超级电容器，比能量为100- 120 Wh/kg，比能量高20倍。卷带设计是一种技术，通过降低大型高功率电池的材料要求，包装和保护成本，使美国生产商能够参与竞争。它以低成本满足了高功率的需求。此外，这种盘形设计具有出色的被动热管理和固有的安全性。节省汽油将减少空气污染和石油进口。
