Can honeycomb-like carbon materials be used as energy storage materials?

Sustainable, conductive, and porous carbon materials are ideal for energy storage materials. In this study, honeycomb-like carbon materials (HCM) are synthesized via a “salty” thermal treatment of abundant and sustainable coffee extract.

What is a honeycomb molded structure?

The honeycomb-based molded structure, which was inspired by bee honeycombs and provides a material with low density and high out-of-plane compression and shear properties, has found widespread use and now plays a critical role in energy conversion and storage technologies such as lithium-ion batteries, solar cells, and supercapacitors.

What is a honeycomb used for?

Engineered (artificial) honeycombs have made significant progress owing to their wide range of uses. Macro-honeycombs, for example, have been used in sandwich panels and are being used in energy applications, including lithium-ion batteries, solar cells, and supercapacitors.

What are Honeycomb based heterostructures?

Due to their promising properties such as low corrosion resistance, excellent strength, high-temperature operation, simple formability and machining, and, most importantly, cost-effectiveness in the industry, honeycomb-based heterostructures have been widely used as energy storage and conversion systems for decades.

Can honeycomb-like carbon be developed?

Future perspectives towards development of honeycomb-like carbon are discussed. Developing low-cost and green electrode materials with high-exposed active sites, rapid ion/electron transport, and tunable surface chemistry are highly desirable for energy storage and conversion devices.

How is honeycomb Si encapsulated?

Via the electrostatic attraction, rapid freeze-drying process, and further thermal treatment, the honeycomb Si can be tightly encapsulated in a thin layer composed of reduced graphene oxide and carbon nanotube (indicating as Si-rGO/CNT) to avoid direct exposure to the electrolyte.
