On january 2, the ministry of commerce publicly solicited opinions on the revision of the catalogue of china's export prohibition and export restriction technologies.

The catalogue was greatly deleted this time, refining the control points of some technical items. After revision, it was 132 items, including 23 prohibited export technologies and 109 restricted export technologies.

Among them, the new battery cathode material preparation technology (No.: 252604X) is restricted in the export part. Control points:

1. Preparation technology of lithium iron phosphate for batteries that meet the following conditions at the same time

(1) general chemical formula LixFeyMzPO4, where x,y,z ≥ 0,M is one or more other elements except Li and Fe

(2) the compaction density of the powder of this material is ≥ 2.58g/cc under 300MPa, the reversible capacity of 0.1C is ≥ 160mah/g, and the efficiency of the first coulomb is ≥ 97%

2. Preparation technology of lithium manganese phosphate for batteries that meet the following conditions at the same time

(2) the compaction density of the powder of this material is ≥ 2.38g/cc under 300MPa, the efficiency of 0.1C for the first time is ≥ 90%, and the reversible capacity of 0.1C is ≥ 155mah/g,0.1C average voltage ≥ 3.85V,1C discharge capacity retention rate ≥ 97%,2C discharge capacity retention rate ≥ 95%

3. Preparation technology of phosphate cathode raw materials

(1) iron phosphate, iron manganese phosphate, ferrous oxalate for battery, diphosphate for battery (1) Lithium hydrogen, lithium phosphate for battery preparation process, in which iron phosphate meets the following conditions at the same time: tap density> 2.1g/cc, magnetic foreign matter <10ppb ".
