New Energy Graphene Energy Storage

Owing to the unique two-dimensional (2D) planar structure, graphene has demonstrated excellent mechanical, electrical, chemical and thermal superiorities, which shows great potential in energy storage and conversion applications.

Both strategies have achieved notable improvements in energy density while preserving power density. Graphene is a promising carbon material for use as an electrode in electrochemical energy storage devices due to its stable physical structure, large specific surface area (~ 2600 m 2 ·g –1), and excellent electrical conductivity 5.

Currently, graphene-based materials play a critical promotion to enhance the performance of these fuel cell components when integrated with graphene-based materials.

Graphene-based nanocomposites have been proven to be suitable for the development of basic materials for alternative energy sources in energy devices. In lithium-ion batteries, graphene endows the battery with high-power density, high energy density, and fast charging speed.

These results indicate that the advanced LFP@C/S-doped graphene composite was an excellent cathode material for lithium energy storage. Liu et al. successfully prepared LFP/graphene composites as cathode materials by one-step microwave heating method.

In fuel cells, graphene is used as an electrode material to enhance electrocatalytic activity. In solar cells, graphene-based composites are used in photovoltaic devices due to their unique high carrier mobility and low resistivity, light transmittance and filling two-dimensional networks, which improves energy conversion efficiency .
