Title: Gerd Krämer: Innovator in Lithium Battery Technology

Introduction

Gerd Krämer is a notable inventor based in Bad Vilbel, Germany. He has made significant contributions to the field of lithium battery technology, holding two patents that showcase his innovative approach to composite materials.

Latest Patents

Krämer's latest patents include "Lithiated silicon/carbon composite materials and method for producing the same." This invention relates to composite materials that comprise lithiated or partially-lithiated graphite or graphene, and silicon with particle sizes ranging from about 1 μm to about 100 μm. These materials have an electrochemical rest potential of less than about 2 V measured against Li/Li. The invention involves mixing graphitic material with silicon powder in a molar ratio of 9:1 to 1:9, along with lithium powder, which constitutes about 10 molar % to 100 molar % of the stochiometrically maximally possible lithium absorption.

Another significant patent is "Stabilised (partially) lithiated graphite materials, methods for the production thereof and use for lithium batteries." This patent describes a coated, (partly) lithiated graphite powder produced in a non-electrochemical process from metallic lithium and graphite powder. The graphite powder is stabilized outside an electrochemical cell by applying a coating layer. It also includes a galvanic cell featuring a cathode, a lithium-conductive electrolyte-separator system, and an anode comprising the coated, (partly) lithiated graphite powder.
