聚乙炔作为合成的有机金属具有极大的应用潜力。MacDiarmid等发现可用电化学方法对聚乙炔进行可逆掺杂,使其电导率达到金属的水平,而且聚乙炔本身具有一个由微纤维组成的网状结构,有很大的表面积(～60m~2/g),因此适合于作二次电池的电极。人们已在实验室制备了各种类型的聚乙炔电池,它们具有重量轻、能量密度高、功率密度大、可充电等特点,因而具有研究价值。沈之荃等曾应用稀土配合催化剂合成了高含量顺式的、热稳定性较高的和抗氧化稳定性的聚乙炔。本文报道稀土聚乙炔电池及其电化学的研究工作。结果表明:稀土聚乙炔电池的开路电压可达3.5V,短路电流达10mA,平均功率密度达160W/kg,具有进一步开发研究的前景。
Polyacetylene as a synthetic organic metal has great potential applications. MacDiarmid et al. Found that the conductivity of polyacetylene can be reversibly doped by electrochemical methods to reach the level of metal. Moreover, polyacetylene itself has a network structure composed of microfibers with a large surface area (~ 60m ~ 2 / g), it is suitable as a secondary battery electrode. People have prepared in the laboratory of various types of polyacetylene batteries, they have the characteristics of light weight, high energy density, power density, rechargeable, and therefore has research value. Shen of Tsuen, who have used rare earth with the catalyst to synthesize a high content of cis, high thermal stability and oxidation stability of polyacetylene. This paper reports the research of rare earth polyacetylene batteries and their electrochemical research. The results show that the open circuit voltage of rare earth polyacetylene battery can reach 3.5V, the short circuit current reaches 10mA and the average power density reaches 160W / kg, which has the prospect of further development.
