Halide-based solid electrolytes, such as Li₃YCl₆ and Li₃InCl₆, are emerging as promising candidates for solid-state batteries due to their high ionic conductivities, exceeding 10⁻³ S/cm at room temperature, and excellent electrochemical stability. These materials offer superior compatibility with high-voltage cathodes, such as lithium nickel manganese cobalt oxide (NMC), enabling the development of high-energy-density solid-state batteries. Research is focused on optimizing the synthesis of halide-based electrolytes, improving their interfacial compatibility with electrodes, and reducing their sensitivity to moisture. For example, the use of ball milling and annealing techniques can produce dense halide electrolytes with grain sizes as small as 100 nm, enhancing ionic conductivity and mechanical strength.
The thermal stability of halide-based electrolytes is another key advantage, with decomposition temperatures exceeding 500°C, compared to 200°C for polymer electrolytes. This makes halide-based electrolytes highly suitable for high-temperature applications, such as aerospace and industrial energy storage. Additionally, halide-based electrolytes are non-flammable and chemically inert, addressing critical safety concerns associated with liquid electrolytes. The development of advanced manufacturing techniques, such as tape casting and screen printing, is driving the commercialization of halide-based solid-state batteries. These techniques enable the production of thin, uniform electrolyte layers with thicknesses as low as 25 µm, enhancing energy density and performance.
From a futuristic perspective, halide-based electrolytes are expected to enable the development of solid-state batteries with energy densities exceeding 600 Wh/kg, compared to 250 Wh/kg for conventional lithium-ion batteries. The exploration of hybrid halide systems, combining halides with polymers or sulfides, is opening new avenues for innovation. Beyond batteries, halide-based electrolytes are being considered for applications in fuel cells, sensors, and electrochemical reactors, where their unique properties can be leveraged to enhance performance. The convergence of materials science, electrochemistry, and engineering is accelerating the realization of halide-based technologies, heralding a new era of safe, high-performance energy storage.
