Preparation of LiNixCol-xO2 Cathode Material for Li-ion Cells邹正光摘 要:The cathode materials LiNixCo1-xO2 (0≤x≤1) for lithium ion battery were prepared in solid phase . The effects of synthesis temperature , the time of heat treatment and also the ratio of raw materials on products were discussed . The residts showed that the products preheated under 600......
Cement Treated Recycled Demolition Waste as a Road Base Material玄东兴摘 要:To enhance the performance of mix granulate road base courses by cement treatment. The mechanical properties of cement treated mix granulate (CTMG) were studied, which was designed with 65% crushed masonry and 35% crushed concrete by mass. The central composite design was employed......
