A fabrication, testing, and imaging laboratory for all solid state batteries

******交通运输部门脱碳对于减缓人为气候变化至关重要，因为交通运输占全球能源相关二氧化碳排放量的23%。通过使交通运输部门电气化，我们将通过使用风能和太阳能等可再生能源，减少大量的本地和全球二氧化碳排放。虽然目前的锂离子电池（LIB）技术已经用于商用乘用车和轻型车辆，但在重型运输和航空领域广泛使用电池电源需要大幅提高电池的能量密度。目前使用液态电解质的LIB技术也存在问题，因为由于不希望的枝晶和气体形成而导致电池膨胀和爆炸的安全问题。******所有固态电池（assb）都使用固体电解质，这对于抑制枝晶生长和相关爆炸事件都非常有吸引力。此外，具有锂金属阳极的assb的理论容量几乎是传统lib的三倍。迄今为止，ASSB的研究还处于起步阶段，大多数研究都集中在分离固体电解质和电极配置的开发上，以最大限度地提高能量密度和反应效率。在设计优化能量密度的多孔材料时，必须考虑主要的输运机制，特别是在assb的电化学界面区域。我们建议开发一种系统，通过x射线断层扫描来研究下一代电池与电化学界面相关的电池动力学。******我们正在申请资金来支持制造和测试系统，以检查下一代电池的形态变化。具体来说，这笔资金将用于固态电池制造和测试系统，该系统将与Bazylak教授的x射线断层扫描仪相结合，建立一个assb的制造、测试和成像实验室。该实验室将包括一个用于材料制备、电极组装和电池组装的手套箱，以及一个电池测试系统，该系统将与Bazylak教授的计算机断层扫描仪相结合，用于并发3D成像和电化学性能表征。该实验室将为Bazylak教授和她的学员提供一个国际上独特的高通量系统，同时进行assb的操作测试和成像，以确定材料形态（如颗粒大小，形状）和降解模式（如颗粒脱落，非导电层）的影响。这里提出的研究将导致下一代assb的新材料设计和制造工艺，并将传播到更广泛的研究界。这项研究的成果将加强加拿大在固态电池开发方面的领导地位，以及与日产和奥迪等国际领先汽车制造商的工业合作。**

******Decarbonizing the transport sector is critical for mitigating anthropogenic climate change since transportation accounts for 23% of global energy-related carbon dioxide emissions. By electrifying the transport sector, we will eliminate significant local and global carbon dioxide emissions via the use of renewable energy, such as wind and solar. While current lithium ion battery (LIB) technologies are already used in commercial passenger cars and light vehicles, the widespread use of battery power in heavy transport and aviation sectors demands a substantial increase in battery energy density. Current LIB technologies with liquid electrolytes are also problematic due to the safety issues of battery swelling and explosion due to undesired dendrite and gas formation. ******All solid-state batteries (ASSBs) use solid electrolytes, which are highly attractive for both inhibiting dendrite growth and associated explosive events. Furthermore, ASSBs with lithium metal anodes exhibit almost triple the theoretical capacity of conventional LIBs. To date, research in ASSB is in its infancy, with most research focused at the development of solid electrolytes in isolation and electrode configurations to maximize energy density and reaction efficiency. The dominating transport mechanisms, particularly in the area of electrochemical interfaces in ASSBs must be accounted for in designing the porous materials optimized for energy density. We propose to develop a system for investigating the battery dynamics associated with electrochemical interfaces in-situ via x-ray tomography for next generation batteries. ******We are requesting the funds to support a fabrication and testing system for examining morphology changes in next generation batteries. Specifically, the funds will be used for a solid state battery manufacturing and testing system, which will be coupled with Prof. Bazylak's X-ray tomography scanner to establish a fabrication, testing, and imaging laboratory for ASSBs. This laboratory will include a glovebox for material preparation, electrode assembly, and cell assembly, and a battery testing system that will be combined with Prof. Bazylak's computed tomography scanner for concurrent 3D imaging and electrochemical performance characterization. This laboratory will provide Prof. Bazylak and her trainees with an internationally unique system for high throughput, concurrent in operando testing and imaging of ASSBs to determine the effects of material morphology (e.g. particles size, shape) and degradation modes (e.g. particle detachment, non-conductive layers). The research proposed here will lead to new material designs and manufacturing processes for next generation ASSBs that will be disseminated to the wider research community. The outcomes of this research will strengthen Canada's leadership in solid state battery development and industrial collaborations with internationally leading automotive makers, such as Nissan and Audi. **
