摘　　要：以有机溶剂THF热生长技术对β MnO2进行改性处理。XRD分析结果表明:改性后β MnO2/THF样品在晶面指数为(102)和(110)面的d值增大;热重分析结果表明:在210℃之前的失重增大;放电结果表明:改性后β MnO2/THF样品的放电性能有显著提高。β-MnO_2 had been modified by solvothermal reaction using THF as a solvent.XRD results indicated that the interface distance, d in (102) and (110) were increased. As compared with sample of β-MnO_2, a high weight loss in modified β-MnO_2/THF had been observed before 210?℃ in TGA pattern. The discharge behaviours were investigated, the discharge characteristics of sample of β-MnO_2/THF was improved significantly.
