Sažetak
Rechargeable lithium-ion batteries (LIBs) have found applications in wide range of devices e.g. mobile phones and notebooks but LiBs also possess great potential for utilization in high power applications, such as hybrid electric vehicles1. The performance of LIBs is greatly determined by the composition, structure and microstructural features of anode and cathode materials. Recent papers point to CoMn2O4 as an attractive candidate for alternative LIBs anode material2-5. The majority of the existing work on battery performance appears to focus on complex morphologies while the studies on the effect of crystal structure on battery performance have been scarce. As-prepared cobalt-dimanganate was prepared by precipitation route. Additionally, samples were thermally treated at T=300, 400 and 500°C. Structural investigation using XRPD and Raman spectroscopy have been carried out in order to correlate specific structural features with preparation conditions and furthermore with electrochemical properties.
