Title:
ANODE FOR LITHIUM-ION BATTERY
Document Type and Number:
Japanese Patent JP2023181115
Kind Code:
A
Abstract:
To provide an anode for a flexible nano-silicon lithium-ion battery in which carbon nanotubes and nano-silicon in the anode are uniformly composited and the nano-silicon is difficult to agglomerate.SOLUTION: An anode 100 for a lithium-ion battery includes: a three-dimensional network structure 102 formed by a plurality of carbon nanotubes intertwined with each other; a plurality of nano-silicon particles 104 coated with amorphous carbon; and two carbon nanotube functional layers 106. The amorphous carbon is obtained by calcining a positively charged carbonizable polymer at high temperatures. The two carbon nanotube functional layers 106 are respectively located on two opposite surfaces of the three-dimensional network structure 102 of the carbon nanotube. The carbon nanotube functional layers 106 each comprise at least two super-aligned carbon nanotube films stacked and crossed with each other.SELECTED DRAWING: Figure 14
