Title
(EN) PROCESS FOR PRODUCING PARTICULATE CARBON-COATED LITHIUM IRON PHOSPHATE, CARBON COATED LITHIUM IRON PHOSPHATE AND ITS USES
(FR) PROCÉDÉ DE PRODUCTION DE PHOSPHATE DE FER LITHIÉ REVÊTU DE CARBONE PARTICULAIRE, PHOSPHATE DE FER LITHIÉ REVÊTU DE CARBONE ET SES UTILISATIONS
Abstract
(EN)
A process for producing particulate carbon-coated lithiumiron phosphate comprising a milling step and a calcination step. The process uses polyvinyl butyral having a butyryl content of at least 84 wt% and a hydroxyl content of 16 wt% or less as a carbon-containing precursor. The process enables the formation of electrodes with higher electrode density.
(FR)
L'invention concerne un procédé de production de phosphate de fer lithié revêtu de carbone particulaire comprenant une étape de broyage et une étape de calcination. Le procédé utilise du polyvinylbutyral ayant une teneur en butyryle d'au moins 84 % en poids et une teneur en hydroxyle de 16 % en poids ou moins en tant que précurseur contenant du carbone. Le procédé permet la formation d'électrodes ayant une densité d'électrode supérieure.
