储能应用的材料设计策略可分为两大类：（1）结构和成分的控制；（2）材料尺寸控制，例如纳米材料的实施。电化学特性的表征决定了能量含量和潜在应用的可行性。同样重要但更具挑战性的是量化活性材料的非法拉第寄生反应以及与电池寿命的关系。了解与植入式心律转复除颤器 (ICD) 电池寿命相关的重要因素对于开发新型 ICD 电池至关重要。阴极材料的原位溶解已被确定为 ICD 电池过早寿命终止的主要因素。本研究对非水 ICD 电池电解液中基准银钒氧化物 (SVO) 材料和两种物理性质不同的银钒磷氧化物（SVPO-H 和 SVPO-R）材料中银和钒的溶解进行了动力学分析。 SVO、SVPO-H 和 SVPO-R 的动力学和机械结果的比较为未来的材料设计方法提供了见解。
Material design strategies for energy storage applications can be considered in two major categories: (1) control of structure and composition and (2) material dimensional control such as the implementation of nanomaterials. Characterization of electrochemical properties determines energy content and possible viability for potential application. Equally critical yet more challenging is quantifying the non-Faradaic parasitic reactions of the active materials and the relationship to battery life. Understanding the significant factors associated with battery lifetimes for the implantable cardioverter defibrillator (ICD) is critical for the development of new ICD batteries. In situ dissolution of the cathode material has been identified as a major factor in premature end of life for ICD batteries. This study contains the kinetic analyses of silver and vanadium dissolution from the benchmark silver vanadium oxide (SVO) material and two silver vanadium phosphorous oxide (SVPO-H and SVPO-R) materials with differing physical properties in a non-aqueous ICD battery electrolyte. A comparison of the kinetic and mechanistic results for SVO, SVPO-H and SVPO-R provides insight for future material design approaches.
