The coulometric titration curve for lithium intercalation in polyacetylene has been determined using poly(ethylene oxide) based solid electrolyte. The plateaus observed suggest the existence of stages, comparable to graphite. This interpretation seems also supported by the cyclic voltammetry scans on polyacetylene. Lithium intercalation appears as a very slow process with estimated at ? 10-13cm2.s-1. 相似文献
A lithium isotope separation was performed using a laser isotope separation method. It was found that the lithium atoms with a natural isotopic abundance enhanced its6Li concentration up to over 90% by tuning the laser wavelength to the2P1/2 of6Li. Too high power, however, leads to a loss of enrichment due to the power broadening effect which was analysed by the equation of motion of density matrices. 相似文献
The potassium lithium niobate crystals have been grown up. The shapes of solid-melt interfaces which maintaining the steady growth of the potassium lithium niobate crystals have been described. The optical transmission spectrum of the crystal has been surveyed. The perfected crystals showed good Second Harmonic Generation properties. 相似文献
The ionic conductivity of polycrystalline lithium nitride has been determined using ac techniques and complex plane analysis. The ionic conductivity is quite high, so that this material may be an interesting lithium-conducting solid electrolyte. 相似文献
