Review-Practical Challenges Hindering the Development of Solid State Li Ion Batteries
Solid state electrolyte systems boasting Li+ conductivity of > 10 mS cm(-1) at room temperature have opened the potential for developing a solid state battery with power and energy densities that are competitive with conventional liquid electrolyte systems. The primary focus of this review is twofold. First, differences in Li penetration resistance in solid state systems are discussed, and kinetic limitations of the solid state interface are highlighted. Second, technological challenges associated with processing such systems in relevant form factors are elucidated, and architectures needed for cell level devices in the context of product development are reviewed. Specific research vectors that provide high value to advancing solid state batteries are outlined and discussed. (C) The Author(s) 2017. Published by ECS. All rights reserved.
