通过在 H[sub 2]SO[sub 4] 酸性溶液中使 LiMnO[sub 4] 与 Mn(NO[sub 3])[sub 2] 直接反应，制备了在（2 [times] 2）通道中不含外来金属阳离子（K[sup +]、NH[sup +][sub 4]、Na[sup +]）的钙锰矿型二氧化锰（HolMO）。 HolMO属于体心四方晶系（空间群14.m），可用式H[sub 4x]Mn[sub 8minus]x]O[sub 16][中心点]yH[sub 2]O表示。初步电化学研究表明 HolMO 有希望作为锂充电电池的阴极。
A hollandite-type manganese dioxide (HolMO), without foreign metal cations (K[sup +], NH[sup +][sub 4], Na[sup +]) in the (2 [times] 2) tunnel, was prepared directly by reacting LiMnO[sub 4] with Mn(NO[sub 3])[sub 2] in an H[sub 2]SO[sub 4] acidic solution. The HolMO belonged to a body-centered tetragonal system (space group 14.m) and could be expressed by the formula H[sub 4x]Mn[sub 8[minus]x]O[sub 16][center dot]yH[sub 2]O. A preliminary electrochemical study suggested that the HolMO is promising as the cathode for a lithium rechargeable battery.
