OUR R&D IS GEARED TOWARD FUTURE BATTERY TECHNOLOGIES
For decades, the use of lithium batteries has been growing at a very fast pace, owing to the considerable advantages of this battery chemistry, especially in terms of energy density. However, with the development of high energy consumption devices, increasingly powerful and fast charging Li-ion batteries are required. Thus, limitations in energy density and safety issues observed lead to the use of suitable technology such as Li-Metal batteries. All-solid-state lithium-ion batteries and lithium metal batteries that have recently come into the spotlight have stimulated research interest in solid-state electrolytes as a promising alternative to conventional liquid electrolytes.
Compared to Li-ion technology, this battery uses lithium metal as anode material requiring a gel polymer electrolyte (GPE) or a solid polymer electrolyte (SPE) to limit or suppress dendritic growth (to avoid eventual short-circuiting). Although very promising results were obtained, solid-state lithium battery technology still suffers from several drawbacks such as: (i) lower conductivity compared to liquid electrolyte, and (ii) low transfer number. Among the various solid-state electrolytes explored to date, single lithium-ion polymers have garnered considerable attention. A salient feature of single lithium-ion polymers is the nearly exclusive contribution of Li+ ions to ionic conductivity, since mobility of anion counterparts is drastically reduced. This exceptional single ion transport behavior in combination with their solid-state nature, flexibility and processability brings remarkable benefits to battery structure and performance.
