LNO and LFO Lithium-rich Li Replenishment Material for Battery Cathode

LNO and LFC Lithium-rich Lithium Replenishment Material for Battery Cathode

Lithium replenishment material for anode and cathode

1. Cathode Lithium-rich Additives

- LNO is applied to ternary cathode materials NCM and NCA.

- LFO(LFC) is applied to LFP and ternary cathode materials.

2. Anode Lithium Replenishment Additives

- LSA，Mainly used in Si-C silicon carbon anode.

Preparation of LNO

Theoretical capacity: 486 mAh/g, can greatly improve the energy density and first cycle efficiency. When above 3.5V, lithium ions are released, can be used as lithium replenishment material for ternary materials.

Li5FeO4(LFO, LFC) Lithium replenishment material for LFP

Advantage of LFO(LFC):

(1) Theoretical capacity: 867 mAh/g.

(2) Charging is suitable for 3.5V-4.0V, when above 2.7V, there is almost no reversible capacity.

(3) The preparation process is short and the process is convenient: one-time sintering.

(4) The purity gradually increases and stabilizes: Li5FeO4 has no other lithium-containing compounds after sintering.

(5) The particles are uniform and the morphology is consistent.
