- Abstract
A high performance lithium anode is a key component for high energy density lithium batteries. Silicon based lithium anode materials are attractive for the lithium anode due to their high theoretical capacity. However, a severe problem is the huge volume change that occurs during cycling, resulting in a poor capacity retention. We have developed a silicon based anode that disperses silicon particles on a carbon paper made from Manila hemp. The composite silicon electrode materials showed a high initial coulombic efficiency of 83%. The initial capacity of 566 mAh g-1 based on the total weight of the electrode was retained at 491 mAh g-1 after 70 cycles at the charge and discharge rate of 100 mA g-1 and at room temperature.
