Смешивание и завод материалов литиевых батарей: катод, анод и шлам

Смешивание материалов литиевых батарей: смешивание порошков и шламов катода (LCO/NMC/LMO) и анода (графит) на двухвальных и плуговых смесителях, плюс вакуумная сушка в одной линии и поставка завода целиком.

Работа батареи начинается со смешивания. Материалы катода (оксид кобальта-лития, NMC, манганат лития) и анода (графит) должны быть смешаны в однородный порошок, а затем в покрасочный шлам без агломератов и с узким, воспроизводимым распределением. Непрерывный двухвальный лопастной смеситель DJHX даёт быстрое и равномерное твёрдо-твёрдое смешивание; плуговой смеситель DLT берёт стадию шлама с высоким сдвигом, где связующее и растворитель должны полностью смочить активный порошок. Линии и комплексные установки см. на странице смесители для литиевых аккумуляторов.

Катод, анод и стадия шлама

Порошки катода и анода сначала сухо премиксуются для равномерного распределения активного материала, затем превращаются в шлам со связующим, проводящей добавкой и растворителем (NMP для катода, вода или растворитель для анода). Шлам должен быть деагломерирован и деаэрирован, чтобы покрытие вышло без пор. Этот двухэтапный маршрут — сухой премикс, затем шлам с высоким сдвигом — это где двухвальный и плуговой смесители делят работу.

Непрерывный двухвальный против плуга для батарейных линий

Для непрерывного сухого премиксования и высокой производительности непрерывный двухвальный лопастной смеситель DJHX флюидизирует слой и выгружает, не открывая сосуд, вписываясь в ритм электродной линии. Для стадии шлама плуговой смеситель с летающими ножами диспергирует связующее и активный порошок в турбулентном слое. Для смены химии с малым остатком конический шнековый смеситель DSHL держит остаток минимальным.

Сушка в той же линии

После смешивания материалы электродов обычно сушат перед покрытием. Вакуумный сушильный смеситель DRH удаляет влагу под вакуумом в одном сосуде, избавляя от отдельной сушилки и перекладки. Его вакуумно-сушильная конструкция защищена нашим китайским патентом на полезную модель ZL 2018 2 1247610.1, охватывающим сочетание смесителя-сушилки для теплочувствительных батарейных порошков.

Типичные технические параметры двухвального смесителя для батарей (DJHX)

ModelWorking volume (L)Motor power (kW)Speed (r/min)
DJHX-300100–1505.541
DJHX-1000400–6001133
DJHX-2000800–120018.531
DJHX-40001600–20003029
DJHX-60002200–35004523

Линейка DJHX охватывает примерно 40–3500 л рабочего объёма и 4–45 кВт мощности мотора; строки выше — представительные точки для службы электродных материалов. Итоговая модель зависит от насыпной плотности, загрузки твёрдого и требуемого времени пребывания — подтвердите пробой на вашей реальной формуле катода или анода.

Заметки по заводу и санитарии

Используйте контактирующие детали SS304/SS316L, полностью открывающиеся двери очистки и дуговые разгрузочные клапаны для быстрой смены химии, заземлите сосуд для проводящих порошков и держите масло редуктора в норме. Мы также поставляем полные заводы материалов батарей — смешивание, диспергирование, сушку и транспорт, спроектированные как одна линия, — чтобы электродный процесс оставался согласованным от сырого порошка до готового к покрытию шлама.

Сопутствующее оборудование
