Cold sintering is a revolutionary ceramic technology in which densification is induced at < 300 degrees C. It is particularly suited to ceramics with Li chemistries, reducing the CO2 emissions associated with ceramic processing at high temperature (700 degrees C. The primary objectives of the project are to optimize the densification of planar multilayers of Li based compositions whilst still retaining high values of Li ion conduction with a view to developing a range of new materials/composites for Li-ion capacitive storage and battery applications.Structure microstructure and properties will be investigated using XRD, SEM, TEM and impedance spectroscopy. Optimised compositions will be used to fabricate planar tapecast layers which will be multilayered and cold sintered to form planar ceramics. A combination of classic and in-operando XRD along with transmission electron microscopy will be used to study the interfacial reactions. The electrical properties will be investigated using impedance spectroscopy. The PhD is part sponsored by the Centre for Dielectrics and Piezoelectrics (CDP), of which the UoS is an academic partner alongside North Carolina and Pennsylvania State Universities. The CDP has 25+ industrial members which include Apple, Samsung, Murata, Taiyo Yuden and Ilika Technologies. Secondments to US partners and to CDP companies are encouraged within the programme.

冷烧结是一种革命性的陶瓷技术，在<300度C下诱导致密化。它特别适合具有李化学的陶瓷，减少了与陶瓷处理相关的二氧化碳排放，在高温下陶瓷处理（700度）。使用XRD，SEM，TEM和阻抗光谱的新材料/复合材料，用于研究的微观结构和特性。界面反应将使用阻抗光谱研究。博士学位是由电介质和压电中心（CDP）赞助的，其中UOS是与北卡罗来纳州和宾夕法尼亚州立大学一起的学术合作伙伴。 CDP拥有25多个工业成员，其中包括Apple，Samsung，Murata，Taiyo Yuden和Ilika Technologies。在该计划中鼓励我们合作伙伴和CDP公司的借调。
