This Small Business Innovative Research (SBIR) Phase I project proposes a unique rolled-ribbon cell for a Lithium-ion battery that has inherent cost advantages for a NGV FreedomCar compact pulse-power application. It can meet the cost requirements and deliver thousands of pulses and recharges. The battery is formed by stacking large capacity (5-10Ah), sealed, 125mm diameter, button cells to optimize power capability. The battery design projects power at 2-4kW/kg and power density at 7.5kW/liter similar to a ultracapacitor, with 20 times greater specific energy at 70-90Wh/kg . Of particular importance to high-power battery, the rolled-ribbon design overcomes safety concerns by its unique internal heat dissipation. Perpendicularly oriented electrode foils remove heat from the electrode interface to the disc-cell hardware without crossing Celgard separator. The high temperature stability of Lithium ion will be enhanced with a flame retardant electrolyte additive. The NGV FreedomCar can anticipate a viable safe, high power Li-ion battery using the rolled-ribbon cell design, that is more compact and cost-effective than ultracapacitors or other high-power batteries. Improved performance and temperature stability for Li-ion battery can enhance prospects for the civilian hybrid vehicle market. Gasoline savings will reduce air pollution and oil imports.

这个小型企业创新研究（SBIR）第一阶段项目提出了一种独特的卷带式锂离子电池，对于NGV FreedomCar紧凑型脉冲电源应用具有固有的成本优势。 它可以满足成本要求，并提供数千次脉冲和充电。 电池由大容量（5-10Ah）、密封、直径125 mm的纽扣电池堆叠而成，以优化功率能力。 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70- 90 Wh/kg。 对于高功率电池特别重要的是，卷带设计通过其独特的内部散热克服了安全问题。 垂直取向的电极箔将热量从电极界面移到盘形电池硬件，而不穿过Celgard隔板。添加阻燃剂可提高锂离子电池的高温稳定性。NGV FreedomCar可以预期使用卷带电池设计的可行安全的高功率锂离子电池，比超级电容器或其他高功率电池更紧凑，更具成本效益。 提高锂离子电池的性能和温度稳定性可以提高民用混合动力汽车市场的前景。 节省汽油将减少空气污染和石油进口。
