Fabrication and characterization of Li2(Fe,Mn)SiO4 cathode materials for new generation lithium-ion batteries

锂离子电池（lib）在日常应用中无处不在，为消费者越来越依赖的各种便携式电子产品提供动力。可以毫不夸张地说，这种便携式电子产品的广泛使用在很大程度上要归功于锂电池，由于相对较高的能量密度和较轻的重量，锂电池的性能优于以前的电池类型。现在，随着我们的社会正朝着交通电气化和太阳能等可再生能源的电网整合的方向发展，lib被要求为插电式混合动力（PHEV）和电动汽车（EV）提供动力，以解决气候变化和化石燃料资源枯竭等严重的全球问题。据预测，到2020年，电动汽车储能产业的年经济产值将达到220亿美元。我们的工业合作伙伴hydro - qu忧郁公司正在积极利用绿色经济的这些方面。在该研究项目中，在hydro - quachimbec的积极支持下，开展了尖端的合作研究，旨在为下一代锂离子电池纳米结构电极材料的开发做出贡献，该材料具有高能量密度、快速充电速率、安全、长寿命和低成本的特点，以满足新兴的电动汽车行业的需求。该项目为突破性材料的研究、高素质人才的培养（项目3年期间将培养20名人才）和先进技术的商业化潜力提供了巨大的机会，最终将带来切实的经济效益。拟议的研究将有助于建立锂离子电池研究能力的临界质量，进一步使加拿大成为快速增长的绿色产业的主要参与者，这对我们可持续的经济和能源未来具有战略意义。

Lithium-ion batteries (LIBs) are omnipresent in everyday applications powering the various portable electronics to which consumers have come to depend on in ever increasing numbers. It will not be an exaggeration to say that such widespread use of portable electronics has largely happened thanks to the LIB that outperforms previous battery types thanks to relatively higher energy density and lower weight. Now LIBs are called to power the plug-in hybrid (PHEV) and electric vehicles (EV) as our society is moving towards electrification of transportation and grid-integration of renewable energy sources like solar to address the serious global issues of climate change and fossil fuel depleted resources. The electric automobile energy storage industry is forecasted to reach an annual economic output of $22 billion by 2020. Our industrial partner, Hydro-Québec, is actively engaged in capitalizing on these aspects of the green economy. In this research program, cutting-edge collaborative research with the active support of Hydro-Québec is undertaken aiming to contribute towards the development of next generation lithium-ion battery nanostructured electrode materials characterized by high energy density, fast charging rates, safety, long lifetime but also lower cost to meet the emerging electric automotive industry needs. The proposed project provides a tremendous opportunity for breakthrough materials research, training of highly qualified personnel (>20 over the 3-year period of the project), and advanced technology commercialization potential that can ultimately lead to tangible economic benefits. The proposed research will help build critical mass of Li-ion battery research capacity further making Canada a major player in the fast growing green industry that is strategic to our sustainable economic and energy future.
