Development of new lithium-ion batteries from wood-based carbon materials with carbon nanotubes

本研究以木材或废木材为原料，采用直接脉冲烧结法制备了具有优良充放电特性的锂离子二次电池，并对其电化学性能进行了评价。通过平衡碳化木材、硅、碳纳米管或长丝的浓度，防止硅的膨胀和收缩引起的裂缝，可以制造高性能的锂离子二次电池。

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.
