Applications
1. Electrolyte Additive in Lithium-ion Batteries
Lithium dihydrogen phosphate is increasingly used as an electrolyte additive in Li-ion battery systems.
It helps improve electrochemical stability, particularly at the cathode–electrolyte interface.
Useful in high-voltage and long-cycle lithium battery chemistries (e.g., LFP, NMC).
2. Ceramic and Glass Materials
Employed as a precursor or dopant in the preparation of lithium-containing ceramics, particularly lithium phosphate-based materials.
Applied in glass manufacturing to modify thermal or optical properties.
3. Research in Solid-State Electrolytes
Investigated as a building block in solid-state lithium electrolytes, such as LiMPO₄ compounds.
Supports R&D for safer, non-flammable batteries.
4. Chemical Intermediate
Can be used in the synthesis of other lithium phosphate compounds, such as lithium iron phosphate (LiFePO₄), a popular cathode material.
