GOALI: Multi-Electron Electrochemical Energy Storage

非技术描述：当前电池存储的低能量限制了当代电子产品的尺寸和重量，从消费电子产品到医疗设备。需要新一代高能量密度的电池组。在这个项目中，二硼化钒每分子释放11个电子的前所未有的能力产生了比锂或锌更大的能量密度，并为大大提高电源组的能量密度提供了机会。今天的电池和燃料电池每个分子只能提供一到两个电子。值得注意的是，二硼化钒的11e存储容量是在平坦、有利、单一的放电电压下释放出来的。人们对这一不寻常过程的限制机制知之甚少。本项目将探索VB2独特的电化学性能。GOALI项目是一项大学与工业界合作的项目，旨在了解用于电池和燃料电池的新型能量密度、多电子材料的不寻常且有前途的氧化还原存储过程。技术细节：在这个项目中，将探索二硼化钒在每个分子中释放11个电子的前所未有的能力，以大大提高电源组的能量密度。这种VB2电荷密度大大大于基于锂或锌的传统电池阳极。值得注意的是，二硼化钒的11e存储容量是在一个平坦的、有利的、单一的放电电位平台上释放的。对于这一不寻常过程的限制机制知之甚少，本项目将探索VB2纳米颗粒独特的电化学性能。这项研究，提供了第一次进入纳米领域的VB2（阳极）电化学。将研究稳定氧化锆涂层纳米颗粒结构，以促进这种不寻常的11电子阳极过程，并在新的VB2纳米复合材料库中形成。对这些过程的基本理解将有助于实现新一代电池组的变革目标，该电池组的容量比现有电池和燃料电池高几倍。电池配置将被优化，以最大限度地提高VB2/空气储能电池的容量。GOALI项目是一项大学与工业界合作的项目，旨在了解用于电池和燃料电池的新型能量密度、多电子材料的不寻常且有前途的氧化还原存储过程。参与该项目的乔治华盛顿大学（GWU）博士后学者以及研究生和本科生研究人员将在GWU接受最先进的基础电化学培训，并通过每年访问行业联络人Lynntech， Inc.，有特别的机会获得工业研发工作场所的经验。

NON-TECHNICAL DESCRIPTION: The low energy stored within current day batteries limits the size and weight of contemporary electronics ranging from consumer electronics to medical devices. A new generation of high energy density power packs is needed. In this project, the unprecedented ability of vanadium diboride to release an exceptional 11 electron per molecule yields an energy density substantially greater than that of lithium or zinc, and provides the opportunity to greatly enhance the energy density of power packs. Today's batteries and fuel cells deliver only one or two electrons per molecule. Remarkably, the 11e- storage capacity of vandium diboride is released over a flat, favorable, singular discharge voltage. Little is known regarding the limiting mechanisms of this unusual process. The unique electrochemical properties of VB2 will be explored in this project. This GOALI project is a collaborative university-industry effort to understand the unusual and promising redox storage process of new energy dense, multi-electron materials for batteries and fuel cells.TECHNICAL DETAILS: In this project, the unprecedented ability of vanadium diboride to release an exceptional 11 electron per molecule will be explored to greatly enhance the energy density of power packs. This VB2 charge density is substantially greater than that of conventional battery anodes based on lithium or zinc. Remarkably, the 11e- storage capacity of vandium diboride is released over a flat, favorable, singular discharge potential plateau. Little is known regarding limiting mechanisms of this unusual process, and the unique electrochemical properties of VB2 nanoparticles will be explored in this project. This research, provides the first foray into the nano-domain of VB2 (anodic) electrochemistry. Stabilizing zirconia coated nanoparticle architectures will be studied to facilitate this unusual 11 electron anodic process and to formulate in a library of new VB2 nano-composites. A fundamental understanding of these processes will be developed towards the transformative goal of a new generation of power packs with several fold higher capacity than existing batteries and fuel cells. Cell configurations will be optimized to maximize the capacity of a VB2/air energy storage cell. This GOALI project is a collaborative university-industry effort to understand the unusual and promising redox storage process of new energy dense, multi-electron materials for batteries and fuel cells. The George Washington University (GWU) postdoctoral scholar and graduate and undergraduate researchers participating in this project will be trained in state-of-the-art fundamental electrochemistry at GWU and have the special opportunity to gain experience in the industrial R&D workplace through visits each year to the industry liason, Lynntech, Inc.
