Abstract Positive electrodes such as LiFePO 4 and LiMnPO 4 nanomaterials with olivine structures are considered as most efficient cathode materials for application in lithium ion batteries. Recently, several methods have been proposed for the preparation of lithium metal phosphates as cathodes for lithium ion batteries and their electrochemical performances have been investigated. Over the last 20 years, several synthetic methods have been proposed for lithium metal phosphate nanomaterials. In t
The best of both worlds: Graphene/ionic liquid (G–IL) layered films were obtained by direct reduction of graphene oxide in the presence of ionic liquids, followed by reassembly through electrostatic layer-by-layer (LbL) adsorption (see picture). The layer spacing of the graphene sheets is regularly expanded upon insertion of ionic liquid molecules (green discs). Selective sensing of aromatic compounds (red spheres) by using the G–IL LbL films was also achieved. Detailed facts of importance to sp
Abstract Energy storage systems for powering electronic medical implants and sensors are essentially based on conventional electrode materials and electrolytes. Because of their toxicity, these battery systems need special encapsulation, which leads to bulky devices. Batteries based on biocompatible electrodes and electrolytes overcome these limitations and hold promise as viable alternatives for powering medical implants and devices. The present review aims at giving an overview of possible bat
