Solid Electrolyte Materials
The Future of Next-Generation Batteries
Solid electrolytes are a revolutionary technology with the potential to transform lithium-ion and sodium-ion batteries. Unlike conventional liquid electrolytes, which are flammable and often contain toxic materials, solid electrolytes are stable, non-flammable, and pose a significantly lower safety risk. This is because they conduct lithium ions through a solid material rather than a liquid solution. This shift not only improves battery safety but also opens the door for a higher energy density.
A major focus of research is on developing all-solid-state batteries, which replace liquid electrolytes entirely with solid electrolytes, leading to significant improvements in energy density, safety, and cycle life. Early research focused on oxide-based electrolytes, followed by polymer electrolytes in the 1980s. More recently, halide solid electrolytes have gained attention due to their promising properties. Today, researchers are actively exploring all-solid-state batteries, composite electrolytes, new materials, and interface engineering to improve the performance and safety of solid electrolyte-based batteries. The search for novel solid electrolyte materials continues, with a focus on materials that offer high ionic conductivity, wide electrochemical window, and compatibility with various electrode materials.
Overall, the field of solid electrolytes is rapidly evolving, with significant progress being made in recent years in the development of new materials and technologies.

Solid Electrolytes for Lithium-ion Batteries
Solid electrolytes offer a key advantage for lithium-ion batteries: they are compatible with lithium metal anodes. Traditional lithium-ion batteries use graphite anodes because lithium metal is highly reactive and can cause safety issues. However, lithium metal boasts a much higher theoretical capacity than graphite, meaning it can store more energy. By enabling the use of lithium metal anodes, solid electrolytes pave the way for batteries with significantly more energy packed into the same size. This translates to longer range for electric vehicles, extended lifespans for our portable electronics, and a potential leap forward in energy storage capacity.

Solid Electrolytes for Sodium-ion Batteries
Sodium-ion batteries (SIBs) are gaining traction as a more sustainable and potentially lower-cost alternative to lithium-ion batteries. The focus for NASICON materials in SIBs seems to be shifting towards their potential as solid electrolytes. Unlike traditional liquid electrolytes, solid electrolytes offer the potential for improved safety and potentially higher energy density. With their exceptional Na-ion conductivity, NASICON materials are well-suited for this role.
