Title:
MIXED SIO 4 AND PO 4 SYSTEM FOR FABRICATING HIGH-CAPACITY CATHODES
Document Type and Number:
WIPO Patent Application WO/2024/006952
Kind Code:
A3
Abstract:
The present technology discloses lithium metal polyanion (LMX) cathode compounds which contain a mixture of SiO4 and PO4 anions. Compounds based on silicate SiO4 anions can exhibit significantly higher gravimetric capacities than conventional lithium iron phosphate (LFP) materials. The present technology offers electrochemical advantages of the LMX compounds over compounds fabricated with only SiO4 anions. Machine learning can be used to provide the synthesis conditions and the stoichiometry of LMX compounds to maximize the gravimetric energy density of a battery cell.
