Iron phosphate precipitation stoichiometry: BYDRecent Research Landscape
Inefficient recovery of spent cathode precursors leads to high raw material costs and environmental penalties. These innovations stabilize the stoichiometric purity of iron phosphate to enable direct reuse in battery manufacturing.
What technical problems is BYD addressing in Iron phosphate precipitation stoichiometry?
Irreversible initial capacity loss
(34)evidences
Lithium consumption during the first cycle prevents full energy density utilization. Mitigating this deficit extends cycle life and increases usable capacity.
Low energy density instability
(31)evidences
Interfacial degradation and side reactions at the electrode-electrolyte boundary lead to capacity fade. Mitigating this instability prevents active material loss and extends cycle life.
Irreversible initial capacity loss
(23)evidences
Insufficient lithium ions during the first charge cycle limits energy density. Restoring lithium inventory prevents premature battery capacity fade.
Low cathode energy density
(16)evidences
Inherent stoichiometric limitations in iron phosphate structures restrict theoretical capacity. Overcoming this bottleneck increases the specific energy of lithium-ion power sources.
