摘要 基于当前电池电极干燥的研究现状，提出并验证了定制的干燥曲线设计。它可以减少干燥时间，同时保持阳极的机械完整性。在三方工艺中，通过在中间干燥阶段调整温和的干燥条件，可以防止活性层对基材的粘附力下降，这种情况通常会随着干燥速率的增加而观察到。该阶段由两个高干燥速率阶段限制，与参考干燥过程相比，可将总干燥时间减少约 40%。
ABSTRACT Based on the state of current research on battery electrode drying, a custom drying profile design is proposed and validated. It allows for drying time reduction, while the anodes’ mechanical integrity is maintained. In a tripartite process, the deterioration of the active layer adhesion to the substrate that is typically observed for increased drying rates is prevented through adjusting mild drying conditions in an intermediate drying stage. This stage is confined by two high drying rate stages which allow for reduction of the total drying time by about 40% compared to a reference drying process.
