New types of boron-based additives for AM printed 5V lithium batteries
Original language description
Nowadays, there is a demand to increase the energy density of lithium batteries. New types of 2nd and 3rd-A generation cathode materials, such as LiNixMnxCoxO2 (NMC), push energy densities up to values of 550 Wh/kg. Even higher energy densities with a theoretical range of up to 700 Wh/kg are achieved by LiNi0.5Mn1.5O4 (LMNO), or lithium cobalt phosphate (LCP) with 800 Wh/kg and operating voltages > 4.8 V. LMNO is also attractive because of its well-developed flat discharge plateau, and the absence of Co is also valuable from a material point of view. However, there are also negatives in the form of low stability of LMNO cells, which are mainly caused by electrolyte instability at high operating voltage and secondly by the dissolution of manganese ions from the structure of the electrode material. Therefore, in the context of solving the given problem, our study focuses on the first area, i.e., increasing the stability of electrolytes and LMNO-based cells using additives based on boron compounds. In the present study, newly synthesized boroxines and carbadodecaborates are studied as additives to obtain high-voltage electrolytes that will increase the stability of LMNO cells.
