Title: Innovations by Reynald Cantave in Electrochemical Cells

Introduction

Reynald Cantave is an accomplished inventor based in Bridgewater, MA (US). He has made significant contributions to the field of electrochemical cells, holding a total of 3 patents. His work focuses on enhancing the safety and efficiency of rechargeable cells through innovative mechanisms.

Latest Patents

Cantave's latest patents include a current interrupter for electrochemical cells. This invention features a current interrupt assembly that is a self-contained, sealed unit, which can be inserted into the cell during construction. The assembly is particularly useful for thin rechargeable cells, forming a crucial part of the electrical pathway between the cell electrode and the corresponding terminal. The mechanism utilizes a thermally responsive member, typically a disk made from a shape memory metal alloy, which deflects when the cell temperature exceeds a predetermined value. This deflection causes a break in the electrical pathway, ensuring the safety of the cell. Additionally, the assembly may include a flexible electrically conductive member and a pressure actuated diaphragm that further enhances its functionality by shutting down the cell when internal pressure exceeds safe levels.

Another notable patent by Cantave is a thermally activated current interrupt mechanism integrated into an end cap assembly for electrochemical cells. This mechanism employs a free-floating bimetallic disk or shape memory alloy member that deforms under elevated temperatures, effectively breaking the electrical pathway and preventing current flow. The end cap assembly also features a pressure responsive mechanism that ruptures under extreme gas pressure buildup, allowing gas to escape safely.
