摘要

摘要由于塑料既便宜又轻便，在我们的日常生活中不可或缺。然而，塑料的广泛使用也带来了处理问题。在各种处理工艺中，塑料回收利用因能最大限度地减少废物和有害副产品而备受关注。在此，我们对最常用的热塑性材料--高密度和低密度聚乙烯进行回收利用，生产出锂离子电池的阳极材料。我们对回收软碳的电化学特性进行了调查，以研究其作为锂离子电池阳极的储能能力。我们的研究结果表明，从塑料废弃物中回收的软碳是一种很有前景的阳极材料。

Recycling of polyethylene via hydrothermal carbonization for the Li-ion battery anode

Because plastics are cheap and light, their use is indispensable in our daily lives. However, the extensive use of plastics causes the disposal issue. Among various disposal processes, plastic recycling is of great attention because of minimizing waste and harmful byproducts. Herein, we recycle the most popular thermoplastic materials, high-density and low-density polyethylene, producing the anode materials for the Li-ion batteries. The electrochemical properties of the as-recycled soft carbon are investigated to study the energy storage capability as the anode of Li-ion batteries. Our work demonstrates the soft carbon recycled from plastic wastes is a promising anode material.

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
