By directly bonding the monolayer organic based electrodes together to assemble the book-like multilayer electrode, increased areal capacity and high flexibility can be achieved. The electrodes represent 5.88 mA h cm−2 at 0.7C and 5.24 mA h cm−2 at 0.2C areal capacity in lithium-ion and sodium-ion batteries, respectively. [ABSTRACT FROM AUTHOR]

A three-dimensional polymeric carbon nitride/graphene framework (CN/GF) was fabricated by the ionic self-assembly of graphene oxide and protonated polymeric carbon nitride nanosheets. As the cathode material in lithium-ion batteries, CN/GF showed an excellent reversible capacity of 184 mA h g−1 at 0.05 A g−1 for 150 cycles and maintained the capacity of 60 mA h g−1 at 5 A g−1.

In this work, a novel strategy to fabricate ternary MoS 2 /SiO 2 /graphene hybrids (MSGs) was developed by incorporating amorphous SiO 2 with MoS 2 and graphene nanosheets. Serving as anode material in lithium ion batteries, the inert silica component can effectively prevent the pulverization caused by the inner-plane volume expansion of MoS 2 . It turns out that MSGs with ∼40 wt% of SiO 2 and ∼42 wt% of MoS 2 manifest the capacity stabilized at 1060 mAh g −1 for more than 100 cycles at the current density of 0.1 A g −1 . Further, this MSG electrode maintains the specific capacity of 580 mAh g −1 at an ultrahigh current density of 8 Ag −1 , which outperforms those of the reported MoS 2 and MoS 2 /graphene hybrids.
