ball milling battery

Jan 01, 2005 The influence of ball milling on the amount of inserted Li in a phosphate phase Lix Fe 2 (PO 4) 3 is shown in Fig. 2. The more the material is ball milled with carbon, the more we have access to its theoretical capacity (90% of the theoretical capacity is obtained for the 240-min ball-milled sample)
