The finished Si/C hybrid anode material can be "grown" onto the Cu foil without using any binder and produces a lot of capacity, high rate capability, and high cyclability. Besides, a cellulose separator made from cotton is found to be superior to traditional polypropylene separators. A modular all-in-one paper-like LIB is assembled by using cellulose as both the separator host and the mechanical skeleton of two electrodes. This research reveals a new way of preparing Si-based anode materials and designing flexible energy storage systems with a large area.

During lithiation-delithiation and increase rate results, a defects-enriched CoMoO 4 / carbon dot with CoMoO4 around 37 nm is achieved by hydrothermal reaction by adding CDs to dampen large volume changes of CoMoO 4 during lithiation-delithiation and increase rate performance. The CoMoO 4 /CD's average lithium ion diffusion coefficient calculated is an order of magnitude larger than that of bulk CoMoOO4, indicating that the CoMoO 4 / CD has promising electrons and lithium ions transportation results as anode material, despite galvanostatic intermittent titration technique.

As anode materials of lithium-ion batteries, Carbon nanowall and carbon nanotube were made. Copper foil was cleaned using ultrasonic cleaner containing trichloroethylene and used as a substrate to produce a lithium-ion battery. Both CNW and CNT were synthesized on Cu foil using plasma-enhanced chemical vapor deposition and water dispersion, respectively. CNT's lithium-ion battery's anode materials were used, while lithium hexafluorophosphate was used as an electrolyte to make another lithium-ion battery. According to the Raman report, composite material containing carbon nanotubes can compensate for the carbon nanowall's flaws.
