Abstract
Nowadays, 3d-metal phosphates are considered as promising electrode materials for metal ion batteries (MIB). A phosphate group increases working potential of the Mn+1/Mn+ redox pair and
provides higher electrochemical and thermal stability that contribute to a longer life of electrodes up
to several thousand charge/discharge cycles. Typically titanium redox transitions are not used for
cathode applications because of low operating potential. Among titanium transitions Ti4+/Ti3+ and
Ti3+/Ti2+, the latter is supposed to demonstrate a lower working potential which is prefferable for
anode materials, however, due to the side conversion reactions, such examples are extremely rare.
The d1
electronic configuration of titanium (III) compounds is more preferable due to the higher
electronic conductivity. Titanium reagents are comparable in cost with those of manganese, are
produced widely and everywhere, non-toxic, and can be easily recycled, making titanium an
attractive element for the industry
