Title: Rolf Hennrich: Innovator in Electrochemical Elements
Introduction
Rolf Hennrich is a notable inventor based in Ellwangen, Germany. He has made significant contributions to the field of electrochemical elements, holding a total of 3 patents. His work focuses on innovative methods for producing rechargeable batteries and high-temperature dischargeable galvanic elements.
Latest Patents
Hennrich's latest patents include a method for producing a rechargeable electrochemical element. This method involves creating a rechargeable button cell with a negative electrode made of a lithium/indium alloy, a positive lithium/intercalating electrode, and an organic electrolyte. The process includes introducing a lithium layer and an indium layer into a negative housing half-section, followed by the positive electrode material in a positive housing half-section. Once the organic electrolyte is added and a separator is placed in between, the two housing half-sections are beaded to form the button cell. A lithium-indium alloy is formed through storage or subsequent charging/discharge cycles.
Another significant patent is for a high-temperature dischargeable galvanic primary element that utilizes an alkaline electrolyte within a metallic annular cylindrical housing. This design features an outer positive silver oxide or manganese dioxide electrode and an inner negative electrode made of a concentrically wound cadmium electrode. The innovative design allows these cells to be stored and tested at temperatures around 200°C for over six weeks without losing operability.
