The Need: In the pursuit of large-scale energy storage solutions, potassium batteries with organic liquid electrolytes have emerged as promising candidates. However, the use of liquid electrolytes presents challenges such as dendritic metal plating and oxygen/sulfur crossover from the cathode. To overcome these limitations and unlock the full potential of potassium batteries, there is a pressing commercial need for advanced solid-state electrolytes with high ionic conductivity, tailored for use in alkaline batteries.

The Technology: Our cutting-edge technology offers a groundbreaking solid-state electrolyte with a formula A(3-x)MyBwCz, where A is a metal cation (Na+, Li+, or K+), M is a monovalent, divalent, or trivalent metal cation, B comprises O2- or S2-, and C is an anion (F-, Cl-, Br-, I-, CN-, NO2-, or a combination thereof). Notably, we've developed a specific variant with A as K+ and B as O2- to maximize performance in potassium batteries.

Commercial Applications:

1. Large-Scale Energy Storage: Our solid-state electrolyte technology opens new avenues for efficient and safe energy storage solutions, revolutionizing the renewable energy sector and power grid stability.
2. Electric Vehicles: By enhancing the safety and performance of potassium batteries, our technology enables longer-lasting and faster-charging electric vehicles, driving the future of clean transportation.
3. Portable Electronics: The advancements in battery safety and stability make our technology ideal for powering various portable electronic devices, ensuring longer operating times and increased user convenience.

Benefits/Advantages:
