| Summary: | Low abundance of lithium in Earth’s crust and its high participation in
overall cost of lithium-ion batteries incited intensive investigation of
sodium-ion batteries, in hope that they may become similar in basic
characteristics: specific energy and specific power. Furthermore, over the
last years the research has been focused on the replacement of organic
electrolytes of Li- and Na-ion batteries, by aqueous electrolytes, in order
to simplify the production and improve safety of use. In this lecture, some
recent results on the selected intercalation materials are presented: layered
structure vanadium oxides, olivine and nasicon phosphates, potentially usable
in both Li and Na aqueous rechargeable batteries. After their
characterization by X-ray diffraction and electron microscopy, the
electrochemical behavior was studied by both cyclic voltammetry and
hronopotenciometry. By comparing intercalation kinetics and coulombic
capacity of these materials in LiNO3 and NaNO3 solutions, it was shown that
the following ones: Na1.2V3O8, Na2V6O16/C , NaFePO4/C and NaTi2(PO4)3/C may
be used as electrode materials in aqueous alkali-ion batteries. |
