Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lithium salt powder dissolution apparatuses face challenges with crosslinking of lithium salt powder, leading to incomplete discharge and difficult powder hopper replacement, which complicates the production of high-quality liquid electrolytes for lithium ion batteries while posing safety risks.
Innovation Solution
A lithium salt powder dissolution apparatus with a closed system where a powder hopper is supported by a vibrating unit and connected via a vibration-proof pipe to a dissolution chamber, allowing for smooth powder discharge and easy replacement, featuring a hopper standing frame for upright positioning and a guard rail for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lithium salt powder is discharged from a powder container, then the powder can be supplied to the dissolution chamber, but crosslinking occurs causing incomplete discharge and entanglement
Solution Approach 1:
The patent applies mechanical vibration to the powder container to prevent crosslinking and entanglement of lithium salt powder during discharge. The vibration mechanism agitates the powder to maintain flowability and ensure complete discharge without residue, directly resolving the contradiction between discharge efficiency and completeness.
2Ease of operation
If a powder hopper is installed at a height of at least 3m, then powder can be supplied to the dissolution chamber, but installation and replacement becomes dangerous and difficult
Solution Approach 1:
The patent segments the powder supply system into a detachable powder hopper unit and a fixed support structure. The hopper can be easily detached and reattached at the required height, eliminating the need for dangerous manual installation while maintaining the necessary elevation for gravity-fed powder supply to the dissolution chamber.
3Object-affected harmful factors
If a closed system is used to prevent moisture contact, then safety and electrolyte quality are improved, but device complexity increases
Solution Approach 1:
The patent merges the powder container, dissolution chamber, and electrolyte solution reservoir into a single integrated closed system. This unified structure eliminates multiple connection points and potential leakage paths, maintaining strict moisture exclusion while actually reducing overall system complexity compared to separate interconnected components.
