Provided are electrodes for lithium-ion batteries comprising: a first lithium metal phosphate material comprising a first plurality of active material particles; and a second lithium metal phosphate material comprising a second plurality of active material particles, wherein both the first lithium metal phosphate material and the second lithium metal phosphate material are LiMPO, wherein M is one or more of iron (Fe) or manganese (Mn), and wherein the first lithium metal phosphate material is blended with the second lithium metal phosphate material at a weight ratio of greater than 1:1.

Electrodes comprising blended active materials

A process of preparing a lithium metal phosphate includes contacting a water-soluble metal precursor, a water-insoluble metal precursor, and a phosphate precursor in an acidic aqueous medium; to form a reaction mixture; precipitating from the reaction mixture a metal phosphate; collecting the metal phosphate; combining the metal phosphate with a lithium precursor; and calcining the combined metal phosphate and lithium precursor at elevated temperature to form a lithium metal phosphate; wherein a mol ratio of water-soluble metal precursor to water-insoluble metal precursor is from 0.5:99.5 to 99.5:0.5.

Method of preparing lithium metal phosphate cathode materials

Provided herein is a cathode. The cathode can include a cathode active material. The cathode can include a coating disposed on the cathode active material. The coating can include LiMMAF(OH), where Mis a first metal, Mis a second metal, A is an anionic species, 1≤x≤2, 0≤y≤1, 0≤z≤1, and 0≤u≤1.

Electrode coatings and components thereof

Described are embodiments of a lithium metal phosphate production methods and systems. The systems and methods can include combining lithium extraction from spodumene, lithium recycling from lithium ion battery ('LIB') black mass, and/or lithium metal phosphate synthesis from metal phosphates.
