Symposium ES06—Alkali Solid Electrolytes and Solid-State Batteries

In the drive towards improved electrical energy storage for applications ranging from electric vehicles to grid stabilization and renewable energy storage, the important role of electrochemical storage and batteries specifically, will continue, due to batteries’ high energy density, simplicity, reliability, and potential for favorable performance/cost ratio. Li-ion batteries are currently in a phase of massive commercial adoption and manufacturing scale-up that will lower costs and catalyze the growth of electrical energy storage in both vehicle and stationary applications. However, the Li-ion technology being scaled up today has a trifecta of performance limitations that incremental progress cannot address: (1) the energy density is limited by the amount of charge that can be practically stored via the intercalation mechanism, (2) thermally-activated degradation modes limit the upper operating temperature to ~ 50 °C and require cooling systems, and (3) the use of organic carbonates in the electrolyte results in cells with intrinsic flammability concerns. These performance limitations have a high potential to be addressed by replacing the negative electrode with Li metal, and the liquid electrolytes in the separator and the porous positive electrode with solid ion conductors. Overcoming this trifecta of performance limitations opens a path to cell costs below 100 $/kWh and pack costs below 175 $/kWh, which would surpass the approximate limits of present Li-ion technology at large scale.

However, there are still significant challenges for solid state batteries including materials, interfaces, characterization, manufacturing, etc. In order to fundamentally understand the problem and promote solid state batteries, this symposium will bring together researchers from companies, national laboratories and universities to fill the knowledge gap in the above issues. Interdisciplinary topics related to physics, materials science and engineering will be connected by invited abstracts in order to accelerate the development of materials, structure designs, manufacturing, and testing.

Topics will include:

  • Ceramic Solid Electrolyte for Li-Ion Batteries
  • Polymer Solid Electrolyte for Li-Ion Batteries
  • Composite Solid Electrolyte for Li-Ion Batteries
  • Alkaline Solid Electrolyte Materials Interface between Solid Electrolyte and Electrode
  • Manufacturing of Solid State Batteries
  • Failure Mechanism and Testing of Solid State Batteries
  • Advanced Characterization of Sold Electrolyte Materials and Solid State Batteries
