| Research Abstract |
In this study, lithium ion secondary battery with excellent charge and discharge characteristics was developed by direct pulse current sintering from carbon anode materials from wood or waste wood, of which electrochemical properties were evaluated. It is possible to make lithium ion secondary batteries with high performance by balancing the concentration of carbonized wood, Si, carbon nanotubes or filaments and to prevent cracks caused by expansion and shrinkage Si.
