Title: The Innovative Contributions of Alex Kaplan

Introduction

Alex Kaplan is a notable inventor based in Providence, Rhode Island. He has made significant contributions to the field of electrochemical cells, holding three patents that showcase his innovative spirit and technical expertise. His work primarily focuses on enhancing the performance and safety of alkaline cells.

Latest Patents

One of Kaplan's latest patents is for an alkaline cell with a semisolid cathode. This invention features a cathode made of manganese dioxide, which remains semisolid during the discharge process. The design includes an anode composed of zinc and an electrolyte of potassium hydroxide. The semisolid nature of the cathode reduces polarization effects, leading to improved manganese dioxide utilization, especially under high current drain conditions. The porosity of the cathode ranges from 45% to 70%, and the volume ratio of the electrolyte solution to the solids is maintained between 0.7 and 2.3.

Another significant patent by Kaplan is a current interrupter for electrochemical cells. This mechanism integrates a thermally activated current interrupt feature into the end cap assembly of the cell. It employs a bimetallic disk or shape memory alloy that deforms at elevated temperatures, breaking the electrical pathway and effectively shutting down the cell. Additionally, the design includes a pressure-responsive mechanism that allows gas to escape in case of extreme pressure buildup, enhancing the safety of the electrochemical cell.
