The broader impact of this Small Business Innovation Research (SBIR) Phase I project will advance a new class of batteries for transportation. The proposed battery design will maximize the rate of charge and battery lifetime while maintaining high energy density, in contrast with current battery research that primarily focuses on maximizing energy density. This new operating parameter will open the design space for smaller batteries that result in lighter weight, lower cost and longer life vehicle platforms to enable all-electric transportation. In addition, the new operating parameters enable the widespread adoption of two new applications, (i) vehicle to grid and (ii) mobility as a service. The associated reduction of greenhouse gases will be 1+ gigaton annually.The proposed project develops a lithium battery coin cell that demonstrates 3 minutes ultrafast charge and 20,000 extended cycle life performance, using the novel disordered rock salt Li3V2O5 anode. This project explores ultrafast charge lithium ion battery platforms. Technical objectives include: 1) charging times comparable to filling up today's gas tanks; 2) batteries with a higher safety profile that last the entire service life of the vehicle; 3) vehicles that can connect to the electric grid for renewables integration.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I阶段项目的更广泛影响将推动新的运输电池。与当前的电池研究相比，所提出的电池设计将最大程度地提高电池寿命和电池寿命，同时保持高能密度，而当前的电池研究主要侧重于最大化能量密度。这个新的操作参数将为较小的电池开放设计空间，从而导致重量较轻，成本较低和寿命更长的车辆平台，以实现全电动运输。此外，新的操作参数还可以广泛采用两个新应用程序，即（i）电网的工具，以及（ii）移动性作为服务。相关的温室气体的减少每年为1+ gigaton。拟议的项目开发了锂电池硬币电池，使用新型的无序岩盐LI3V2O5阳极，显示3分钟超快电荷和20,000延长的循环寿命表现。该项目探讨了超快电荷锂离子电池平台。 技术目标包括：1）充电时间可与当今的汽油箱相当； 2）具有更高安全性的电池，可以延续车辆的整个使用寿命； 3）可以连接到电网以进行可再生能源集成的车辆。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
