Abstract Recently, two-dimensional transition metal dichalcogenides, particularly WS2, raised extensive interest due to its extraordinary physicochemical properties. With the merits of low costs and prominent properties such as high anisotropy and distinct crystal structure, WS2 is regarded as a competent substitute in the construction of next-generation environmentally benign energy storage and conversion devices. In this review, we begin with the fundamental studies of the structure, properties and preparation of WS2, followed by detailed discussions on the development of various WS2 and WS2-based composites for electrochemical energy storage and conversion applications. In the end, some prospective prospects and promising developments of WS2 in these fields are proposed. Keywords Transition metal dichalcogenides · Tungsten disulfide · Exfoliation · Energy storage and conversion
1 Introduction The increasingly serious environmental deterioration issues and the limited stock of fossil fuels have severely influenced our daily life and global economy, which accordingly, stimulate extensive scientific researchers to exploit novel energy storage devices with superior performances, low cost, and the eco-friendly feature. Among various new energy storage technologies, the electrochemical energy storage and conversion (EESC) systems have gained particular attention since they effectively resolved the impending shortage of nature resources such as sunlight, wind and tide. Moreover, EESC devices are critical enabling technologies for clean energy, high-efficiency energy conservation and storage, reduction of atmospheric contaminant emission. The key to maintain the excellent performance of EESC systems is the optimal selection of materials, especially the electrode materials. Therefore, it is necessary to develop appropriate materials

to solve the critical problems related to energy and environment [1–3]. New materials hold the key to fundamental advances in EESC, both of which are vital in terms of meeting the pressing challenge of global warming and the finite nature of fossil fuels. Nanotechnologies promote the cognitive revolutionary of human being, and have been touted as the next industrial revolution. Nanomaterials in particular offer unique properties or combinations of properties as electrodes and electrolytes in a range of energy devices. Progress towards EESC technol
