Latest Patents

Arntzen's latest patents include an innovative design for an electrochemical cell. This design features two outer electrodes and a central electrode of opposite polarity, all housed within a symmetrical casing that forms an offset configuration. The outer electrodes are strategically nested within raised portions of the housing, while the central electrode is securely engaged with the internal surfaces. This structure minimizes void volume, which could otherwise be filled with gas or heavy electrolyte, and provides essential sealing and support for interelectrode separator layers.

Another significant patent involves a method for preparing an electrochemical cell in an uncharged state. This process is particularly relevant for lithium alloy-transition metal sulfide cells. The negative electrode is composed of materials like aluminum or silicon, which alloy with lithium during charging. The positive electrode is created by blending lithium sulfide, transition metal powder, and electrolytic salt, which is then heated and pressed onto a conductive substrate to form a plaque. This innovative approach allows for the formation of lithium alloy within the negative electrode and transition metal sulfide within the positive electrode during the first charge cycle.
