Compliance with the ESD protection requirements of international standards is crucial for personal protective equipment (PPE) to guarantee safety in hazardous environments and static-sensitive facilities, including in ATEX zones, automotive and electronics manufacturing, cleanrooms, oil & gas, and mining, chemical, pharmacy, and medical facilities. Graphene nanotubes ensure compliance with ESD safety standards, providing stable, humidity-independent electrical resistance to all elements of the uninterrupted grounding chain of ESD-safe clothing.
The unique morphology and properties of graphene nanotubes provide stable anti-static properties and additional functionality to PPE. The granted electrical conductivity ensures high-level ESD protection according to international standards and additional functionality for protective wear, such as dust repellency and touch-screen compatibility. Ultralow working dosages, which are dozens of times lower that of other anti-static additives, make it possible to maintain final product durability and color flexibility, preserving mechanical properties and standard processing.

The pitch-derived soft carbon and SWCNTs provided an excellent conductivity, and the porous structure of the composite accommodated the stress produced by the Si expansion.
High thickness and specific capacity leads to areal capacities of up to 45 and 30 mAh cm−2 for anodes and cathodes, respectively. Combining optimized composite anodes and cathodes yields full cells with state-of-the-art areal capacities (29 mAh cm−2) and specific/volumetric energies (480 Wh kg−1 and 1,600 Wh l−1).
The all‐nanomat full cell shows exceptional improvement in battery energy density – 479 Wh/kg battery, and Si-anode capacity – 1166 mAh/g.
The use of SWCNT conductive additive enables graphite-free SiO electrodes with 74% higher volumetric energy and superior full-cell cycling compared to graphite electrodes.
Areal capacities greater than 10 mAh/cm2 and volumetric capacities greater than 1400 mAh/cm3 can be achieved.
Replacing Denka black with SWCNT allows to reduce the carbon content to 0.2 wt% to further increase the energy density, and 2 wt% of PVDF was shown to benefit the cycling stability due to the mitigated PVDF-induced side reactions from its direct contact with NCA particles.
