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

以木材和废木材为原料，采用直流脉冲烧结法制备了具有良好充放电性能的锂离子二次电池，并对其电化学性能进行了评价。可以通过平衡软木、Si、碳纳米管或丝的浓度来制造具有高性能的锂离子二次电池，并且防止由Si的膨胀和收缩引起的裂纹。

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.
