Development of 3D hybrid electrolytes and nanostructured electrodes for scalable manufacturing of new-generation high-energy density solid-state lithium batteries********

锂离子电池（LIBs）是一种“隐形”技术，它使移动电子产品的大量普及以及最近电动汽车的商业化成为可能。此外，lib在存储太阳能等间歇性可再生能源产生的电力方面的应用越来越多。然而，由于使用易燃的有机溶剂电解质，这些电池存在固有的安全漏洞，因此最近发生了一些与智能手机，汽车甚至飞机有关的壮观灾难性事件。与此同时，当前状态的锂离子电池的能量密度相当有限，无法满足更多封装电源的需求。例如，电池组的能量密度决定了电动汽车在需要充电之前的行驶里程。虽然我们可以把这些电池组做得越来越大，但由于成本和重量/体积，这是适得其反的，因此我们需要开发新一代电池，在合理的成本下，安全、高能量密度。在这种情况下，人们普遍认为，到目前为止，采用固体电解质、锂金属作为阳极和高压阴极的固态锂电池是实现这一目标的最佳选择。然而，这种发展受到许多挑战的阻碍，例如固体电解质的设计，该电解质在t室具有良好的离子电导率，并且在与锂金属阳极和阴极的界面处具有低电阻。另一个巨大的挑战是防止锂金属阳极生长所谓的树突（一种树状延伸），这种树突会穿透电解质导致电池故障。但解决这些问题的方式必须允许以具有竞争力的成本进行可扩展的制造。为此，我们的团队与LIB研发领域的世界领导者Hydro-Quebec合作，提出设计和开发一种新的复合电解质，该电解质由多孔陶瓷框架制成，填充了电化学稳定的导电聚合物，并与新型纳米工程阳极和高压阴极相连接。拟议的研究构成了一个具有巨大创新潜力的主要技术突破的原始方法，从而在快速增长的市场中引领先进的制造活动。********

Li-ion batteries (LIBs) are the "invisible" technology that enabled the tremendous proliferation of mobile electronics and more recently the commercialization of electric vehicles. Additionally, LIBs find increasing use in storage of electricity generated from intermitting renewable sources like solar. These batteries however suffer from an inherent safety vulnerability due to the use of flammable organic solvent electrolytes hence some recent spectacular catastrophic incidents with smart phones, cars and even airplanes. At the same time the energy density of current state LIBs is rather limited to meet the demand for more packaged power. It is the energy density of a battery pack for example that determines the driving range of an electric car before it requires recharging. While we can make these battery packs bigger and bigger this is rather counterproductive because of cost and weight/volume hence we need to develop new generation batteries that will be safe and with high energy density at reasonable cost. In this context, it is widely accepted that building solid-state lithium batteries incorporating a solid electrolyte, Li metal as anode, and a high-voltage cathode by far offers the best option to achieve this goal. Such development however is hampered by a number of challenges as are the design of a solid electrolyte that can have good ionic conductivity at room-T and low resistance at the interface with the Li metal anode and the cathode. Another big challenge is to prevent the Li metal anode for growing so-called dendrites (sort of tree-like extensions) that can lead to battery failure by penetrating through the electrolyte. But solving these problems has to be done in a way that allows for scalable manufacturing at competitive cost. To this end our team in collaboration with Hydro-Quebec, a world leader in LIB R&D, proposes to design and develop a new composite electrolyte made of a porous ceramic framework filled with electrochemically stable conducting polymer and interfaced with a novel nano engineered anode and a high-voltage cathode. The proposed research constitutes an original approach with great innovative potential for major technological breakthroughs leading to advanced manufacturing activity in a fast growing market.********
