Titanium balls as sacrificial anode were electrolyzed at 0?2 A for 6 h in ethanol and acetylacetone solution of 0?04 mol/L Bu?4NBr,and then 0?35 g lithium slices were added into it.

• 以"牺牲"阳极溶解法在c(Bu4NBr)=0 04mol/L的乙醇和乙酰丙酮混合溶液中,控制电流强度在0 2A,电解钛片6h,再向所得溶液中加入0 35g锂片,制得复合氧化物纳米粉体LiTi2O4的前驱体。 将含有前驱体的电解液直接水解,控制pH=8 5左右。
