Title
(EN) CONTINUOUS EFFICIENT PRODUCTION PROCESS FOR LITHIUM BATTERY SLURRY
(FR) PROCÉDÉ DE PRODUCTION EN CONTINU EFFICACE POUR BOUILLIE DE BATTERIE AU LITHIUM
(ZH) 一种锂电池浆料连续化高效生产工艺
Abstract
(EN) Provided is a continuous efficient production process for lithium battery slurry. According to the process, a bonding agent can be directly added into a continuous production line, adhesive liquid prefabrication by the bonding agent is not needed, and the production efficiency is improved. The technical solution of the continuous efficient production process for lithium battery slurry comprises: first mixing a major material, an auxiliary material, and some of a liquid material at a front section of a tube body of a spiral mixing apparatus, the tube body further comprising a middle section and a back section, and the front section, the middle section, and the back section are arranged in sequence; then selectively adding the bonding agent into the front section or the middle section; and finally adding the remaining liquid material into the back section, the back section being provided with a discharging port.
(FR) L'invention concerne un procédé de production en continu efficace pour bouillie de batterie au lithium. Selon le procédé, un liant peut être directement ajouté dans une ligne de production en continu, une préfabrication de liquide adhésif par le liant n'est pas nécessaire, et l'efficacité de production est améliorée. La solution technique du procédé de production en continu efficace pour bouillie de batterie au lithium comprend : le premier mélange d'une matière principale, d'une matière auxiliaire et une partie d'une matière liquide dans la section avant d'un corps de tube d'un appareil de mélange en spirale, le corps de tube comprenant en outre une section médiane et une section arrière, et la section avant, la section médiane et la section arrière sont agencées en séquence; puis l'ajout sélectif du liant dans la section avant ou la section intermédiaire; et enfin l'ajout de la matière liquide restant dans la section arrière, la section arrière étant pourvue d'un orifice d'évacuation.
(ZH) 本发明提供一种锂电池浆料连续化高效生产工艺,该工艺可将粘接剂直接加入连续生产线中,无需使用粘接剂预制胶液,提高了生产效率。本发明一种锂电池浆料连续化高效生产工艺的技术方案包括:首先,将主材、辅料和部分液体料在螺旋混合装置的筒体前段进行混合,所述筒体还包括中段和后段,所述前段、中段和后段依次设置;其次,在所述前段或中段可选择性的加入粘结剂;最后,在所述后段加入剩余液体料,所述后段设有出料口。
