摘要

Lithium ion batteries are widely used as a power supply for IT devices such as mobile phones, and today they are starting to be used in applications such as electric vehicles. Research on these lithium ion batteries began with the conductive polymer polyacetylene (PA). In batteries which use water-based electrolyte, the water is electrolyzed due to the application of 1.5V, and thus it is impossible to achieve an electromotive force higher than that. To realize batteries with high energy, capacity and voltage, it is necessary to use non-water-based organic electrolytes. In the early 1980s, when rechargeable secondary batteries using non-water-based organic electrolytes were being developed, there was a need for new anode materials to substitute for metallic lithium, and attention turned to PA as such as material.
