Metal based material coated silicon alloy anode materials using silicon alloy E were prepared in a similar fashion according to the procedure outlined in the preparation of metal based material coated silicon alloy B. See Table 11 for the weights of each precursor.
The metal based material coated silicon alloy E was then mixed with, a respective graphite composition, LiPAA, and deionized water using a MAZERUSTAR mixer for 18 min (Table 12). The resulting slurry was then coated onto a 15 μm copper foil using a coating bar with a 0.006″ gap and dried over 2 h in the air. The drying coatings were calendered to 30% porosity according to the calculation. After the calendar, the coatings were further dried under vacuum at 120° C. for 2 h. The final dried coating composition ratio of EE-67 4.5 wt % Cu2(OH)3(NO3) coated silicon alloy E/MAGE/KS6/LiPAA was 30/50/10/10. Coin cell electrodes were then punched from the foil.
