Latest Patents

Two of Ginette Lessard's most notable patents include the following:

1. **Process for cutting polymer electrolyte multi-layer batteries and batteries obtained thereby**: This innovative method involves preparing a stacking of battery laminate consisting of anode, polymer electrolyte, and cathode films, along with an optional insulating film. The process allows for the assembly to be cut into predetermined shapes using a mechanical device, ensuring that the films do not suffer from macroscopic deformation or induce permanent short circuits. The resulting battery exhibits a uniform cut, and the edges of the anode films are protected by an electronically insulating passivation film.

2. **Ultra thin solid state lithium batteries and process of preparing same**: In this patent, Lessard introduces a mother-battery that comprises an anode made from metallic lithium or sodium, along with a polymer electrolyte serving as both a conductor for alkaline ions and a separator. The innovative design also incorporates a composite cathode. After preparing a laminate mother-battery of considerable surface area, a precise mechanical cutting process produces thin polymer electrolyte batteries, which retain their voltage post-cutting through a self-healing mechanism.
