The systematic study of oxide bronzes in the period 1950-1980 paved the way to further advances in the solid state chemistry of oxides, including the alkali metal intercalation(deintercalation chemistry by soft chemical and/or electrochemical methods. These techniques also gave access to new metastable compounds such as several new f...展开更多
