Title
(EN) INORGANIC BINDERS FOR IMPROVED ANODES IN RECHARGEABLE ALKALI METAL ION BATTERIES
(FR) LIANTS INORGANIQUES POUR ANODES AMÉLIORÉES DANS DES BATTERIES MÉTAL ALCALIN-ION RECHARGEABLES
Abstract
(EN) Inorganic binders comprising silicon or phosphorus have been discovered that offer advantages for use in rechargeable alkali metal ion battery anodes. These improved anodes are less hydrophilic and not subject to the deformation that can occur in conventional anodes from water absorption even at dry room levels. However, the performance characteristics in batteries is comparable to or even better than that obtained from conventional anodes. Also advantageously, these anodes can be prepared from aqueous slurries.
(FR) On a découvert des liants inorganiques comprenant du silicium ou du phosphore qui présentent des avantages pour une utilisation dans des anodes de batteries métal alcalin-ion rechargeables. Ces anodes améliorées sont moins hydrophiles et ne sont pas sujettes à la déformation qui peut se produire dans des anodes classiques en raison de l'absorption d'eau même dans des conditions ambiantes sèches. Cependant, les caractéristiques de performance dans les batteries sont comparables ou supérieures à celles obtenues avec des anodes classiques. Avantageusement, ces anodes peuvent être préparées à partir de suspensions aqueuses.
