ENHANCING THE LOW-TEMPERATURE CHARACTERISTICS OF A LI/GRAPHITE HALF-CELL BY THE COMPREHENSIVE MODIFICATION OF ELECTROLYTE

Rakhatkyzy, Makpal; Nurpeissova, Arailym; Kalimuldina, Gulnur; Belgibayeva, Ayaulym; Bakenov, Zhumabay (National Laboratory Astana, 2022-08)

In this work, a complex modification of the lithium salt and solvents was applied simultaneously to develop an optimal electrolyte system with improved low-temperature characteristics for the Li/graphite half-cell.
LOW-TEMPERATURE PERFORMANCE OF SNXP/C COMPOSITE NANOFIBERS AS FREE-STANDING ANODE MATERIALS FOR LITHIUM-ION BATTERIES

Belgibayeva, Ayaulym; Rakhatkyzy, Makpal; Rakhmetova, Aiym; Kalimuldina, Gulnur; Nurpeissova, Arailym; Bakenov, Zhumabay (National Laboratory Astana, 2022-08)

Graphite anode is admitted as one of the critical limiting factors for applying lithium-ion batteries (LIBs) in low-temperature (LT) environments. As an alternative, tin compounds, such as SnO2, exhibit much better LT ...
