Lithium Battery Material Silo

Product Overview

The lithium battery material silo is specialized equipment used for storing and conveying lithium battery cathode and anode materials (such as lithium iron phosphate (LFP), ternary materials, graphite, etc.).

Inner wall materials: 304/316L stainless steel, 2205 duplex steel (for highly corrosive environments).

Structural Design

(1) Material and Surface Treatment

The silo body is constructed from 304/316L stainless steel. The inner surface undergoes mirror polishing (with a roughness of Ra≤0.8μm), preventing material residue and corrosion, and meeting the cleanliness standards of lithium battery production. For key components in contact with corrosive materials, special materials such as Hastelloy and polytetrafluoroethylene (PTFE) are used to enhance corrosion resistance.

(2) Safety Protection Design

Equipped with multiple safety facilities including explosion-proof devices, pressure relief valves, and nitrogen protection systems, it effectively prevents potential hazards like dust explosions. Additionally, it features functions such as upper and lower level alarms for material levels and overload protection for conveying equipment, ensuring comprehensive safety during operation.

(3) Modularity and Flexibility

Adopting a modular design, it can be flexibly combined according to factory floor space and production requirements, enabling independent operation of a single silo or coordinated control of multiple silos. The equipment supports quick disassembly, assembly, and maintenance, reducing downtime and maintenance costs.

Application Scenarios

(1) Cell Manufacturing Process

Used for the storage and transportation of cathode materials (such as lithium iron phosphate and ternary materials) and anode materials (such as graphite), ensuring a stable supply of materials during processes like mixing and coating, and improving the consistency of cell production.

(2) Battery Assembly Process

Suitable for storing materials such as separators and electrolytes. Through precise metering and conveying, it ensures the accuracy of material ratios during battery assembly, enhancing battery yield and performance.

(3) Other Lithium Battery-related Scenarios

Applicable for temporary storage and transportation of materials during lithium battery recycling processes, as well as for storing small batches of materials in lithium battery R&D laboratories.
