Ion substitution
Web13 jul. 2024 · Sodium ion batteries (SIBs) have recently been promising in the large-scale electric energy storage system, due to the low cost, abundant sodium resources. Mn … WebBoth forms of substitution lead to smoothing of the associated voltage profile as well as reduced charging time at high voltage (>4.8 V vs. K/K+). These changes effectively suppress electrolyte decomposition, thereby enhancing the capacity retention in the ion-substituted KV(1 −x)TixPO4+yF1−y materials.
