LIBs were analysed in the previous section. Here, we deal essentially with electrochemical double layer capacitors . These batteries and capacitors utilize carbon materials as electrodes.
However, then we can see the development of synthetic diamonds by the GE high-pressure catalytic process initiated in 1941 and leading to the first commercially successful synthesis on december 1954. Much later the diamond and diamondlike films appeared, using low temperature and low pressure, truly defiant of all the laws of thermodynamics and phase diagrams. One of the most exciting events of all has been the explanation for the formation of anisotropic, graphitizable carbons via the intermediate phase of mesophase, that nematic, aromatic, discotic liquid crystal system. These new discoveries and developments had an impact that extends well beyond the confines of academic research and worked the beginning of a new era in carbon science and technology.
Lithium Ion Batteries
Moreover, it is worth mentioning that nanoparticles tend easily to aggregate either during their synthesis or post treating or galvanostatic cycling, leading to loss of surface area for Li+ ion transfer. A proper solution is to generate TiO2 nanoclusters, where the primary TiO2 nanoparticles are separated by conductive material at a certain distance. Lee, J.W.; Hong, J.K.; Kjeang, E. Electrochemical characteristics of vanadium redox reactions on porous carbon electrodes for microfluidic fuel cell applications. Electrochim. Acta 2012, 83, 430–438. Recently, hybrid energy storage devices termed as supercapattery, are developed to complement the figures of supercapacitors and batteries.
- Pt-free ORR catalysts, the transition metal, nitrogen, and carbon groups, or M-N-C materials, are attractive candidates due to their high surface area, high activity, and low cost.
- Since aluminium is quite an active metal, the traditional smelting technique used for iron did not work, and electrolysis, with the significant development of the electrical generator, was the only practical method to enable the electrolytic aluminium production.

- The carbon fibers are other excellent carbon materials whose development led to the carbon fiber reinforced plastic and other composite products, which have several uses in aerospace and non-aerospace structures, as well as in non-structural applications.

In a Dye Solar Cell, the charge separation happens at the interface of the titanium dioxide and the dye. Remember that this interface is present all over the internal surface of a porous layer. This allows the Dye Solar Cell to form many separated charges for a given area. The nanostructure of the Dye Solar Cell is one of the secrets of its efficacy. Zhu, X.; Ye, J.; Lu, Y.; Jia, X.
