Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing ternary materials in lithium-ion batteries, such as the co-precipitation/high-temperature solid-phase method, are inefficient, energy-intensive, and costly, with limitations in processing capacity, washing effectiveness, and safety, failing to meet the requirements of green manufacturing for efficiency, energy saving, and emission reduction.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional automatic centrifuge is used for filtering and washing, then solid-liquid separation speed is improved, but processing volume is limited and washing effect is poor
Solution Approach 1:
The centrifuge drum is divided into multiple filtering cavities (first filtering cavity, second filtering cavity, etc.) with independent filtering surfaces, allowing simultaneous processing of multiple batches or larger volumes of material, thereby increasing processing volume while maintaining separation speed
Solution Approach 2:
The filtering cavities are arranged in a nested or stacked configuration within the drum structure, with filtering surfaces positioned at different levels or depths, enabling compact arrangement of multiple filtering zones to maximize processing capacity within limited space
2Quantity of substance
If automatic centrifuge with thick filter cake is used, then low water content is achieved, but washing time increases and washing liquid consumption increases
Solution Approach 1:
The filter cake is segmented into multiple layers or zones corresponding to different filtering cavities, with each cavity having its own filtering surface and discharge mechanism, allowing parallel washing and processing of different material portions to reduce overall washing time
Solution Approach 2:
The filtering process is optimized to produce filter cake with controlled thickness and uniform structure before washing begins, pre-conditioning the material to facilitate faster and more efficient washing, thereby reducing both washing time and liquid consumption
3Adaptability or versatility
If automatic centrifuge is used for batch production, then production flexibility is maintained, but power consumption increases and safety decreases
Solution Approach 1:
The centrifuge is designed to operate continuously with multiple filtering cavities that can process material in sequence or parallel, eliminating idle time between batches and maintaining continuous useful action, thereby reducing overall power consumption while preserving batch production capabilities
Solution Approach 2:
The centrifuge operates with variable speed control, adjusting rotation speed dynamically based on the specific batch requirements, material properties, and processing stage, optimizing energy consumption while maintaining the flexibility to adapt to different production needs
4Ease of operation
If traditional washing operation is used, then operator can access centrifuge for washing, but labor intensity increases and washing effect is poor
Solution Approach 1:
The centrifuge incorporates self-washing capabilities with automatic washing mechanisms that can clean the filtering surfaces and internal components without requiring manual intervention, thereby improving washing efficiency while reducing labor intensity and maintaining accessibility when needed
