Purpose-built for storing and transporting lithium salt raw materials in the lithium battery industry. The inner wall is electropolished and the outer wall finely mirror polished; the smooth interior reduces lithium salt powder clinging and caking, lowering material loss. Suited to low-temperature warehousing through ambient production, its pressure capability meets sealed conveying needs, and a side viewing window shows the remaining material level at a glance. The sturdy body suits forklift transfer and clean storage across lithium salt production, dispensing and transfer.
