A strategy of lattice‐reversible binary intermetallic compounds of metallic elements is proposed for applications in flexible lithium‐ion battery (LIB) anode with high capacity and cycling stability. First, the use of metallic elements can ensure excellent electronic conductivity and high capacity of the active anode substance. Second, binary intermetallic compounds possess a larger initial lattice...
Lithium–Ion Batteries
In article number 2105172, Jiaping Wang and co‐workers propose lattice‐reversible binary intermetallic compounds with zinc blende structure as a promising anode material for high‐performance flexible lithium–ion batteries. The micron‐sized indium antimonide/carbon nanotube electrodes with low volume expansion demonstrate outstanding cycle stability, rate performance, and flexibility...
Carbon nanotubes (CNTs) are regarded as one of the most promising materials to manufacture high‐performance lithium batteries. This prospect is closely related to the construction of macroscopic architectures of CNTs. The superaligned CNT (SACNT) array is a unique kind of vertically aligned CNT array. Its highly oriented feature and strong intertube force facilitate the fabrication of macroscopic...
A novel and simple strategy is developed to construct ultralight and 3D pure carbon nanotube (CNT) aerogels by the spontaneous expansion of superaligned CNT films soaked in a piranha (mixed H2SO4 and H2O2) solution, followed by cryodesiccation. The macroscopic CNT aerogels have an extremely low apparent density (0.12 mg cm−3), ultrahigh porosity (99.95%), high specific surface area (298 m2 g−1), and...
