Frequently Asked Questions
What is the maximum operating speed of the coating equipment?
The equipment is designed to operate at a maximum speed of up to 5 meters per minute (Max 5m/min), depending on the process requirements.
Which coating methods are supported by this system?
This machine supports both continuous coating and transfer gap coating methods to accommodate different battery production needs.
What materials can be processed with this equipment?
The principal materials compatible with this system include lithium cobaltate, ternary materials, lithium iron phosphate, and lithium manganate.
What is the viscosity range and coating width capability?
The equipment handles slurry viscosity ranges from 1500 to 30000 cps and supports a coating width between 100mm and 300mm.
What is the dry coating thickness and its tolerance error?
The dry coating thickness ranges from 50 to 200 μm. The thickness error is kept within ±2μm for one side and ±3μm for both sides, excluding the 8mm margin at the edges, head, and tail.
What quality standards must the finished coating meet?
