Introduction

Norman L Willmann is a notable inventor based in Anderson, IN (US). He has made significant contributions to the field of battery technology, holding a total of 2 patents. His work focuses on improving the efficiency and functionality of mat-immobilized-electrolyte batteries.

Latest Patents

Willmann's latest patents include a "Separator for mat-immobilized-electrolyte battery" and a "Method of making a mat-immobilized-electrolyte battery." Both inventions involve an electrolyte-immobilizing mat that comprises a plurality of randomly oriented resilient fibers resistant to and wettable by sulfuric acid electrolyte. The mat is held in a stressed, precompressed state by a resin that is substantially insoluble in sulfuric acid but is sufficiently degradable under battery formation conditions. This allows the mat to swell within the battery cell element during formation. Thermosetting resins, particularly melamine-formaldehyde, are preferred for these applications, and the invention is particularly useful with mats made from glass fibers.
