MnO_2电极可充性能的研究—化学改性法

Study on Rechargeability of MnO_2 Electrode-Chemical Modified Method

本文通过石墨共沉淀这一化学改性法，证实廉价易得的石墨材料对Mno_2电极的可充性有一定的改善。经过化学反应使Mn（OH）_2与石墨共沉淀，通氧气使Mn（OH）_2氧化成Mn_2O_3，干燥脱水后的Mn_2O_3再经酸化歧化成为所需MnO_2样品，并探讨了石墨选型对MnO_2电极改性的影响．

Through chemical modified method-graphite codeposition, study provedthe low-priced, easy- obtained graphite can improve there chargeability of Mn(OH)_2 elec-trode. The chemical reaction resulted in the codeposition of Mn(OH)_2 and graphite while Mn(OH)_2 changed into Mn2O3 by oxygenenating. The required MnO2 samples were obtained by-acidifying and then by dispositionating the dried, dehydrated Mn2O3. It was also discussed inthis paper about the influence of graphite selective models on MnO2 modified e1ectrode.
