Firstly, we will build upon recent breakthrough experimental work [1] on high-performance graphene laminate supercapacitors to optimise separately on 1) energy density and 2) devising cost-effective methods to scale up production from sustainable precursors. In parallel, we will perform the first experimental proof-of-concept work to validate our recent theoretical proposal for a new paradigm of EES - the pseudocapacitive battery - [2] that uses a novel-pseudocapacitive storage mechanism, taking advantage of the novel, expanded layered materials we can produce [3]. This proposed pseudocapacitive Faradic energy storage mechanism mimics the charging properties of a conventional supercapacitor, providing an "ideal" pseudocapacitive response. The charge storage through "quantised capacitance" is an observable Faradaic mechanism in nanoparticles arising from electronelectron interactions, which has been theoretically proved to satisfy the required criteria for ideal pseudocapacitance. In theory, this innovative charge scheme leads to a developed capacitive, yielding the combination of high power density and energy density long sought by the field [2]. The student will be trained in a range of complementary analytical techniques for testing electrochemical performance and materials characterisation at the Physics Department and Electrochemical Innovation Laboratory (UCL Chemical Engineering) and PC labs at QMUL for device manufacture and electrochemical characterisation. During the first three months, the student will be trained in a range of complementary characterisation techniques, including diffraction, XPS, Scanning Probe and Advanced TEM methods. Additionally, the student will receive training in a range of topics that will support their research progress, including science communication, research ethics, career development planning and data science.

首先，我们将基于最近的突破性实验工作[1]对高性能石墨烯层压式超级电容器，以分别优化1）能量密度和2）设计具有成本效益的方法，以从可持续前体来扩展生产。同时，我们将执行首个实验概念验证工作，以验证我们最近的EES新范式的理论提案 - 假能力电池 - [2]使用新颖的假性储存机制，利用新颖的，扩展的分层材料，我们可以生产[3]。该提出的伪能源储能机制模仿了常规超级电容器的充电性能，从而提供了“理想”的假能力响应。通过“量化电容”的电荷存储是由电子相互作用引起的纳米颗粒中可观察到的法拉达机制，理论上已被证明满足了理想假能力的所需标准。从理论上讲，这种创新的电荷方案导致了发达的电容，从而产生了高功率密度和能量密度的结合[2]。该学生将接受一系列补充分析技术的培训，用于测试物理部和电化学创新实验室（UCL化学工程）和QMUL的PC Labs的电化学性能和材料表征，以进行设备制造和电化学表征。在最初的三个月中，学生将接受一系列互补表征技术的培训，包括衍射，XPS，扫描探针和高级TEM方法。此外，该学生将接受一系列主题的培训，这些培训将支持他们的研究进度，包括科学沟通，研究伦理，职业发展计划和数据科学。
