A Novel Flexible Full-Cell Lithium Ion Battery Based on Electrospun Carbon Nanofibers Through a Simple Plastic Package

Abstract

The paper reports a novel flexible full-cell lithium ion battery (LIB) through a simple plastic package method. Carbon nanofibers (CNFs) are synthesized by electrospinning technology and the subsequent carbonation process. The CNFs with three-dimensional interconnected fibrous nanostructure exhibit a stable reversible capacity of 412 mAh g−1 after 100 cycles in the half-cell testing. A full cell is assembled by using CNF anode and commercial LiCoO2 cathode, and it displays good flexibility and lighting LED ability. The aggregate thickness of the constructed full-cell LIB is approximately 500 μm, consisting of a CNFs/Cu film, a separator, a LiCoO2/Al film, electrolyte, and two polyvinyl chloride (PVC) films. The structure, morphology, and the electrochemical performances of electrospun CNFs and LiCoO2 electrodes are analyzed in details.

Characterization and Preparation of Nano-porous Carbon Derived from Hemp Stems as Anode for Lithium-Ion Batteries

“…The first discharge specific capacity and charge specific capacity are 2469.7 mAh/g and 1168.1 mAh/g, respectively. The first cycle has poor coulomb efficiency (only about 36%), which is consistent with the common characteristics of lithium-ion batteries cycle performance [15, 20]. The huge capacitance loss of the first cycle is attributed to the irreversible consumption of a large amount of lithium ions by the solid electrolyte interface (SEI) film forming on the electrode surface due to the large specific surface area.…”

Effect of Deep Cryogenic Activated Treatment on Hemp Stem-Derived Carbon Used as Anode for Lithium-Ion Batteries

“…The first discharge specific capacity and charge specific capacity of CAC-500 are 2469.7 mAh/g and 1168.1 mAh/g, respectively. The relatively poor coulomb efficiency of first cycle (only about 36%) is in a good agreement with the common characteristics of lithium-ion batteries cycle performance [ 38 , 39 ]. It is the large amount of lithium ions consumed by the solid electrolyte interface (SEI) film formed in the first cycle due to the large specific surface area that leads to the huge capacitance loss of the first cycle.…”
