Existing energy storage devices face challenges in preventing short-circuiting and carry current between electrochemical cells, which can lead to reduced efficiency and safety concerns.
Innovation Solution
The proposed energy storage device includes a plurality of electrochemical cells with at least two of the positive electrode, negative electrode, and electrolyte in a liquid state, along with external harnesses configured to hold wires in electrical isolation. The harnesses are positioned between electrochemical cells and made of insulating materials, such as ceramic, to prevent electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If wires are positioned close to electrochemical cells to reduce device size, then device compactness is improved, but the risk of short-circuiting and carry current between cells increases
Solution Approach 1:
The patent introduces harnesses made of insulating materials (such as ceramic materials) as intermediary components between the wires and the electrochemical cells. These harnesses hold the wires in electrical isolation from the cells and from each other, preventing short-circuiting and carry current while allowing the wires to be positioned close to the cells for compact device design.
2Reliability
If insulating harnesses are positioned between electrochemical cells to prevent short-circuiting, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The harnesses serve multiple functions simultaneously: they provide electrical insulation between wires and cells, hold wires in proper positioning, and prevent carry current between cells. This multi-functionality reduces the need for separate components for each function, thereby minimizing the increase in device complexity while achieving reliable short-circuit prevention.
