Negative electrodes for Na-ion batteries.

Research interest in Na-ion batteries has increased rapidly because of the environmental friendliness of sodium compared to lithium. Throughout this Perspective paper, we report and review recent scientific advances in the field of negative electrode materials used for Na-ion batteries. This paper sheds light on negative electrode materials for Na-ion batteries: carbonaceous materials, oxides/p...

Microstructural Analysis of the Effects of Thermal Runaway on Li-Ion and Na-Ion Battery Electrodes

Thermal runaway is a phenomenon that occurs due to self-sustaining reactions within batteries at elevated temperatures resulting in catastrophic failure. Here, the thermal runaway process is studied for a Li-ion and Na-ion pouch cells of similar energy density (10.5 Wh, 12 Wh, respectively) using accelerating rate calorimetry (ARC). Both cells were constructed with a z-fold configuration, with ...

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...
