Metal hydro-borates for Li- and Na-ion batteries

Recent Progress in Graphite Intercalation Compounds for Rechargeable Metal (Li, Na, K, Al)‐Ion Batteries

Lithium-ion batteries (LIBs) with higher energy density are very necessary to meet the increasing demand for devices with better performance. With the commercial success of lithiated graphite, other graphite intercalation compounds (GICs) have also been intensively reported, not only for LIBs, but also for other metal (Na, K, Al) ion batteries. In this Progress Report, we briefly review the app...

Organic negative electrode materials for Li-ion and Na-ion batteries

This thesis work comprises work on novel organic materials for Liand Nabatteries, involving synthesis, characterization and battery fabrication and performance. First, a method for improving the performance of a previously reported Li-ion battery material (lithium benzenediacrylate) is presented. It is demonstrated that applying freeze drying in combination with carbon coating in the liquid sta...

Todorokite-type manganese oxide nanowires as an intercalation cathode for Li-ion and Na-ion batteries

Nanomaterials Meet Li-ion Batteries.

Li-ion batteries are used in many applications in everyday life: cell phones, laser pointers, laptops, cordless drillers or saws, bikes and even cars. Yet, there is room for improvement in order to make the batteries smaller and last longer. The Fromm group contributes to this research focusing mainly on nanoscale lithium ion cathode materials. This contribution gives an overview over our curre...

Electrochemical properties of iron oxide nanoparticles as an anode for Li-ion batteries

The synthesis of iron oxide nano-particles by direct thermal decomposition was studied. Simultaneous thermal analysis and Fourier transform infrared spectroscopy results confirmed the formation of iron-urea complex, and disclosed iron oxide formation mechanism. Calcination of the iron-urea complex at 200°C and 250°C for 2 hrs. resulted in the formation of maghemite along with hematite as a seco...
