A novel dual-ion battery constructed with aluminum foil anode and mesocarbon microbead cathode is designed in this work based on an ionic liquid electrolyte. The battery shows only 2% decrease after 300 cycles. Moreover, the energy density of the packaged battery can be estimated to be 221 W h kg−1 at the power density of 109 W kg−1, much higher than most commercial lithium-ion batteries.

A facile and binder-free coating method, termed Langmuir–Blodgett–Scooping, is reported. The method takes advantage of Marangoni stresses and self-assembly to rapidly create functional coating films of various nanomaterials, with single-particle thickness resolution, at an air–water interface (left). Transfer of the film to a conventional separator yields membranes that enhance cathode material utilization in lithium–sulfur batteries (right).

Engineering smart nanobiointerface which can interact with cells as an artificial niche, that can response to the change of external stimuli, remains a great challenge. Herein, it is demonstrated an electrochemical-responsive nanobiointerface, composed of conducting polymer (polypyrrole) nanoarray, enables highly efficient cell adhesion/detachment with desirable viability along with its dynamic hydrophobic/hydrophilic switching.
- Impact of Conformality and Crystallinity for Ultrathin 4 nm Compact TiO2 Layers in Perovskite Solar Cells

Highly conformal ≈4 nm compact TiO2 layers by atomic layer deposition are demonstrated to match the performance of ≈50 nm spray-pyrolysis TiO2 layers in mesoporous perovskite solar cells. TiO2 films are characterized by grazing-incidence X-ray diffraction using a synchrotron source. Film thickness and conformality are found to be more critical to a high-performing compact TiO2 layer than the degree of crystallinity.
- Structural Evolution of 3D Nano-Sn/Reduced Graphene Oxide Composite from a Sandwich-like Structure to a Curly Sn@Carbon Nanocage-like Structure during Lithiation/Delithiation Cycling

3D nano-Sn/reduced graphene oxide (RGO) composite has a sandwich-like structure with ≈10 nm Sn particles adhering homogeneously on the interfaces and surfaces of RGO nanosheets. The composite exhibits excellent lithium storage performance, especially the extra-long cycle life. This superior cycle performance is mainly attributed to the structural evolution from a sandwich-like structure to a Sn@carbon nanocage-like structure during cycling.
