Latest Patents
Cheeseman's latest patents include a current interrupter for electrochemical cells. This invention features a thermally activated current interrupt mechanism integrated into an end cap assembly for an electrochemical cell. The mechanism utilizes a free-floating bimetallic disk or shape memory alloy member that deforms when exposed to elevated temperatures. This deformation causes a break in the electrical pathway, effectively shutting down the cell to prevent overheating. Additionally, the design incorporates a pressure-responsive mechanism that allows gas to escape from the cell when extreme pressure builds up.
Another notable patent is a current interrupt assembly for electrochemical cells. This self-contained, sealed unit can be inserted into the cell during construction and is particularly useful for thin rechargeable cells. The assembly includes a thermally responsive member that breaks the electrical pathway when the cell temperature exceeds a predetermined value. It also features a pressure actuated diaphragm that shuts down the cell when internal pressure exceeds safe levels.
