项目摘要

Rechargeable batteries play important roles in implantable medical devices such as deep-brain stimulators to suppress tremors. In such applications, safety is of primary importance. The state-of-the-art anode for such batteries is lithium titanate that operates at a high potential mitigating safety concerns. However, high potential results in a significantly reduced energy density, thereby limiting the applications of these batteries. New Nb-based anode materials are promising in that they continue to operate at safe potentials but allow to nearly double the lithium storage and can be operated at higher rates giving a higher power. However, these materials have, to date, not been integrated into implantable devices due to detrimental transformations during battery use such as particle cracking. Herein, in-situ characterization will be used to fully understand these transformations in order to design a material that is more resilient under the conditions required for implantable devices. Then, a wide variety of material compositions will be screened in high-throughput fashion in order to mitigate these physical limitations. Furthermore, machine-learning algorithms will be utilized to dramatically increase the number of explored materials and predict to what extent co-substitution may be beneficial. In collaboration with our industrial partner, Medtronic Inc., the newly developed materials will be tested under realistic conditions to confirm their viability for medical devices. The development of these higher energy safe batteries will enable new implantable devices in the neuromodulation category and wearable devices such as sensor/monitors (e.g. glucose sensors). These new economic opportunities are important for Canadians both in terms of improved personal health and for the benefits to Medtronic manufacturing facilities in Canada.
可充电电池在植入式医疗设备中发挥着重要作用,例如用于抑制震颤的脑深部刺激器。在这些应用中,安全性是最重要的。这种电池的最先进的阳极是钛酸锂,它在高电位下工作,减轻了安全问题。然而,高电势导致能量密度显著降低,从而限制了这些电池的应用。新的铌基阳极材料是有前途的,因为它们继续在安全电位下工作,但允许锂储存量增加近一倍,并且可以在更高的速率下工作,从而提供更高的功率。然而,由于在电池使用过程中的有害转化,例如颗粒破裂,这些材料迄今为止尚未被整合到可植入装置中。在此,将使用原位表征来充分了解这些转变,以便设计出在植入式设备所需条件下更具弹性的材料。然后,将以高通量方式筛选各种各样的材料组合物,以减轻这些物理限制。此外,机器学习算法将被用于大幅增加探索材料的数量,并预测共同替代可能有益的程度。与我们的工业合作伙伴美敦力公司合作,新开发的材料将在实际条件下进行测试,以确认其用于医疗设备的可行性。这些更高能量安全电池的开发将使神经调节类别中的新植入式设备和可穿戴设备如传感器/监测器(例如葡萄糖传感器)成为可能。这些新的经济机会对加拿大人来说非常重要,无论是在改善个人健康方面,还是在为加拿大的美敦力制造设施带来利益方面。
