Internationally, Canada has held a significant lead in clean energy conversion and storage technologies for decades. In 2014, Canada ranked sixth in the world for investment in new domestic clean energy storage projects. In this regard, electrochemical energy storage systems such as Li-ion batteries (LIBs) and supercapacitors are under serious consideration as efficient and less polluting power-storage systems. Their potential applications are in electric vehicles and mobile miniaturized electronic devices. However, for their widespread utilization and commercialization, markets demand a solid-state and flexible design with an enhancement of their energy/power density and safety. These technical barriers are associated with the structure of the main compartments of these systems, including unsafe and voluminous liquid electrolytes. Thus, the main goal for this 5-year proposed research is to develop solid-state, multifunctional electrolyte membranes based on hexagonal boron nitride (h-BN) nanostructures with high performance and durability. H-BN, known as “white graphene”, has a similar crystal structure to graphene and has attracted a great deal of attention from the scientific community because of its distinct physical and chemical advantages over graphene. Specifically, due to having a permanent electrically insulating nature, h-BN has a strong potential to be manipulated and applied in LIBs and supercapacitors as a reliable solid-state electrolyte and produce safe, fully solid-state clean-energy storage systems with high energy and power densities.It is expected that the results of the proposed research will provide the breakthrough needed to make solid-state energy storage systems commercially viable technologies through performance and durability improvements. The success of the proposed research and the training of highly qualified personnel (HQP) will contribute highly needed technology and expertise to the fields of electrochemical engineering and materials science, required for the business activities and enterprises of energy and electronics industries in Canada. This will strengthen the position of Canadian companies specializing in clean energy within a competitive global market and contribute to the development of a knowledge-based Canadian economy. In this way, Canada will maintain its place as an international leader in the development of two emerging technologies (i.e., nanotechnology and clean energy) within a fast-paced industry.

数十年来，加拿大在国际上一直在清洁能源转换和存储技术方面拥有重要的领先优势。 2014年，加拿大在新的国内清洁能源存储项目中投资了全球第六名。在这方面，诸如锂离子电池（LIB）和超电容器之类的电化学能源存储系统被认真考虑为高效且污染更少的电源储能系统。它们的潜在应用是在电动汽车和移动小型电子设备中。但是，对于它们的宽度利用和商业化，市场需要增强其能量/功率密度和安全性的固态和灵活设计。这些技术障碍与这些系统的主要隔室的结构有关，包括不安全和大量的液体电解质。这是这项为期5年提议的研究的主要目标是基于具有高性能和耐用性的六角硼（H-BN）纳米结构，开发基于六角硼（H-BN）纳米结构的固态多功能电解质膜。 H-BN被称为“白石墨烯”，其晶体结构与石墨烯具有类似的晶体结构，并且由于其与石墨烯的物理和化学优势不同，因此引起了科学界的广泛关注。 Specifically, due to having a permanent electrically insulating nature, h-BN has a strong potential to be manipulated and applied in LIBs and supercapacitors as a reliable solid-state electrolyte and produce safe, fully solid-state clean-energy storage systems with high energy and power densities.It is expected that the results of the proposed research will provide the breakthrough needed to make solid-state energy storage systems commercially viable technologies through performance and durability improvements.拟议的研究的成功和高素质人员的培训（HQP）将为加拿大的商业活动和能源和电子行业的企业和企业所必需的电子工程和材料科学领域贡献急需的技术和专业知识。这将加强加拿大公司在竞争激烈的全球市场中专门从事清洁能源的地位，并为基于知识的加拿大经济的发展做出贡献。通过这种方式，加拿大将在发展快速行业的两种新兴技术（即纳米技术和清洁能源）开发方面的国际领导者。
