The preparation of biomass carbon materials and its energy storage research

摘要

The energy is the material basis to support the whole process of human civilization, and it is also an integral part of modern social development basic condition. Wind, solar, tidal power, geothermal energy, and other all belonging to renewable clean energy will become the main energy source in the future. However, renewable energy generally has a large amount, low energy density, randomness, and intermittent, which cause it hard to use. In this situation, the development of efficient energy storage to meet human demand for energy is to become a hot spot in the worldwide. Electrochemical energy storage of high efficiency and low investment and the use of safe, flexible application characteristics have attracted people for the further research of this kind of energy storage methods. And lithium-ion batteries and battery as nowadays most rapid development, the paper first summarizes the development status of the existing lithium-ion battery. Then proposes a kind of by large algae biomassEnteromorpha as precursor system of lithium-ion battery cathode materials and assemble them into analog battery. At last, the electrochemical properties and physical structure have been characterized in the paper.
