The LiFePO4/C cathode material was synthesized by two–step addition of dual carbon sources method based on the in situ polymerization method combining with two–step sintering process. In this study, the structure and morphology have been studied systematically by X–ray diffraction (XRD) and scanning electron microscope (SEM).The electrochemical performances have been shown by the charge/discharge capacity, rate property, cycle performance. It was evidenced that the two–step addition of dual carbon sources had remarkable advantages, including the more complete coating carbon, and the improvement in the electrochemical performance of LiFePO4/C.

This review provided information about the development of the synthesis aspect, preparation and application of mesoporous carbon in the global world based on research phenomenon on 100 mesoporous carbon papers published by Elsevier, ACS dan Springer during 25 year. Review results showed that researcher began to leave sucrose and switch to non-sucrose as carbon precursor. Researchers used sucrose about 90% in 1995-2000 and in 2010-2015 decrease to become 40%. Otherwise those using non-sucrose in 1995-2000 only 10%, recently increase to 60%. For the method used to synthesis the mesoporous carbon researcher prefer used soft template (about 75 %) before year 2000 and hard template (about 60%) in 2000-2010, but now the method used with soft templates, hard templates and combinations of both are balanced. From year 1995 until 2015 total researcher used sucrose as carbon precursor about 50% and researchers about 40% using hard template method, 35% using soft template method and the others using combination both of them. Structure form of the amorphous carbons are grown, from wormholes, cubic, until hexagonal, and modification to these fours forms. Physical properties such as pore size, surface area, and structural order were developed for better performance year to year. Mesoporous carbon application up to 60% were used in the fuel production and refineries, but the other using on the communication tenhnologies and medical areas. All of the mesoporous carbon in the global world shows that mesoporous carbon is a future material which has a great opportunity to develop especially in Indonesia and other developing countries. Indonesia have  various natural resources as a carbon source, so in the future Indonesia are expected as one of the countries of mesoporous carbon supplier<br /><p> </p>

The nitrogen-doped mesoporous carbon spheres have been synthesized via soft-template and hydrothermal synthetic strategies using phenol/formaldehyde resins as carbon sources and melamine as a nitrogen source. The obtained carbon spheres exhibit a spherical morphology with a size range of 3-5 μm, which possess the narrow microporosity (ca. 1.2 nm) and mesoporosity (ca. 4 nm), large surface area (560-1200 m2 g-1) and high nitrogen contents (up to 15.7 wt%). Due to the well-developed porous structure and high nitrogen content, the carbon spheres show high performance for hydrogen storage, and the hydrogen adsorption capacities are in the range of 140-185 cm3 g-1, which is better than that of most activated carbons. The incorporation of nitrogen into carbons is favored for hydrogen uptake in low pressure.
