| Outline of Final Research Achievements |
In the present study, by applying a technique in Li secondary batteries, a memristor effect is aimed by controlling electric conductivities of Li ternary compounds on the basis of reversible changes in their electronic structures which originate from insertions/extractions of Li ions. Especially, the electronic structures of Li2CN2 Li7MnN4 are studied by using a code, Wien2k and their transport properties are simulated. The electric conductivity of Li2CN2 shows a significant change by extracting Li from Li2CN2, showing a promising material for memristors. However, Li2CN2 actually shows a rapid hydroxylation in air, suggesting that Li2CN2 powder is needed to be dispersed in a polymer layer to prevent air.
