Available in PDF, EPUB and Kindle. Book excerpt: The ability to harvest and convert solar energy has been associated with the evolution of human civilization. The increasing consumption of fossil fuels since the industrial revolution, however, has brought to concerns in ecological deterioration and depletion of the fossil fuels. Facing these challenges, humankind is forced to seek for clean, sustainable and renewable energy resources, such as biofuels, hydraulic power, wind power, geothermal energy and other kinds of alternative energies. However, most alternative energy sources, generally in the form of electrical energy, could not be made available on a continuous basis. It is, therefore, essential to store such energy into chemical energy, which are portable and various applications. In this context, electrochemical energy-storage devices hold great promises towards this goal. The most common electrochemical energy-storage devices are electrochemical capacitors (ECs, also called supercapacitors) and batteries. In comparison to batteries, ECs posses high power density, high efficiency, long cycling life and low cost. ECs commonly utilize carbon as both (symmetric) or one of the electrodes (asymmetric), of which their performance is generally limited by the capacitance of the carbon electrodes. Therefore, developing better carbon materials with high energy density has been emerging as one the most essential challenges in the field. The primary objective of this dissertation is to design and synthesize functional carbon materials with high energy density at both aqueous and organic electrolyte systems. The energy density (E) of ECs are governed by E = CV2/2, where C is the total capacitance and V is the voltage of the devices. Carbon electrodes with high capacitance and high working voltage should lead to high energy density. In the first part of this thesis, a new class of nanoporous carbons were synthesized for symmetric supercapacitors using aqueous Li2SO4 as the electrolyte. A unique precursor was adopted to create uniformly distributed nanopores with large surface area, leading to high-performance electrodes with high capacitance, excellent rate performance and stable cycling, even under a high working voltage of 1.6V. The second part of this dissertation work further improved the capacitance of the carbon electrodes by fluorine doping. This doping process enhances the affinity of the carbon surface with organic electrolytes, leading to further improved capacitance and energy density. In the third part, carbon materials were synthesized with high surface area, capacitance and working voltage of 4V in organic electrolyte, leading to the construction of prototyped devices with energy density comparable to those of the current lead-acid batteries. Besides the abovementioned research, hierarchical graphitic carbons were also explored for lithium ion batteries and supercapacitors. Overall, through rational design of carbons with optimized pore configuration and surface chemistry, carbon electrodes with improved energy density and rate performance were improved significantly. Collectively, this thesis work systematically unveils simple yet effective strategies to achieve high performance carbon-based supercapacitors with high power density and high energy density, including the following aspects: 1) Constructed electrodes with high capacitance through building favorable ion/electron transportation pathways, tuning pore structure and pore size. 2) Improved the capacitance through enhancing the affinity between the carbon electrodes and electrolytes by doping the carbons with heteroatoms. 3) Explored and understand the roles of heteroatom doping in the capacitive behavior by both experimental measurement and computational modeling. 4) Improved energy density of carbon electrodes by enlarging their working voltage in aqueous and organic electrolyte. 5) Scalable and effective production of hierarchically porous graphite particles through aerosol process for use as the anode materials of lithium ion batteries. These strategies can be extended as a general design platform for other high-performance energy storage materials such as fuel cells and lithium-ion batteries.

This book was released on 2016 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical energy storage (EES) plays an important role in people's daily lives, with devices such as rechargeable batteries for cell phones, computers, and electric cars. Electrochemical, thermal, and mechanical storage systems are just a few of the many types of energy storage systems. In all these systems, a supercapacitor is critical for energy storage. Due to a supercapacitor's high power density, outstanding cycle stability, and long life span, it is widely used in memory backup, hybrid cars, electric vehicles and emergency systems; it plays an essential role to replace tradition fossil fuels in the car markets. Unlike lithium-ion batteries (Libs), the energy density of supercapacitor is very low (about 1/10 of Libs) which limits its applications greatly. How to increase the energy density of a super capacitor without altering beneficial properties is an essential topic in the energy community and attracts numerous attentions for decades. Energy density E= 1⁄2 CV2, C here is the specific capacitances, it mainly relies on the materials of the electrodes. Many types of electrode materials have been investigated for their ability to increase energy density, among these materials, carbonaceous materials (activated carbon, carbon nanotube, carbon cloth, graphene, graphite, reduces graphene oxide (rGO), carbon monolith and et al.) are used most commonly as electrodes or as a supporting matrix for metal compounds in electrodes. Due to the easy synthesis process, low cost, large surface area, easily controllable porosity and thermal and chemical stability, activated carbon (AC) is the most popular form of carbon electrode material. Besides, the source to get AC is very rich, it mainly can be derived from biomass and bio-waste. The nano-structures of carbon sources are inherited in the AC, such as layered structure, sponge-like structure and diamond structure. The reviews of different carbon as the electrode materials were given in Chapter 1. The carbon sources used in this research are algae and oil tea shells separately, with ZbCL2 as the activation agent. For algae-derived-carbon (ADC), a high capacitance (325 F/g @ 0.5A/g) and a large surface (>1500m2/g) were obtained. However, the rate capability is poor; we further study the storage mechanism by dividing the surface areas into micropore (2nm), mesopore (2 to 50nm) and macropores ( 50nm) areas. Generally, The contributions of micropores, mesopores and macropores to the capacitances are different, using the specific capacitances measured from the electrochemical tests, combing the data of surface areas and pore volumes obtained from the N2 adsorption and desorption data at 77K; the capacitance of each single nanopore is calculated, assuming the cylindrical structures of all the nanopores; the results are identical to the published works. Metal compounds especially for the transition metal oxides are other types of common electrode materials due to the high theoretical capacitances, revisable redox reactions happen during the charge and discharge cycles, which help to transfer/store more electrons than the carbon materials. However, the electrical conductivities and efficient active surface areas for redox reactions of metal oxides themselves are low, which reduce their performances in specific capacitance, rate capability and cycle stability. Normally, metal oxides need to combine with carbon materials, such as activated carbon, carbon nanotubes, graphene and et al. to improve the conductivities and expand the active surface areas. The ADC shows a sponge-like structure which is ideal to be used a scaffold to support the metal oxides. The activated carbon supported CoO was synthesized by treating algae with Co (OH)2, the assessed as an electrode material. It was observed that the capacitance, rate stability, and cycle stability were enhanced significantly, as compared to the pure CoO as the electrode materials applying this simple method, it is easy to scale up the productions from laboratory level to industry level. In chapter 2, we used ADCs to study the pore size and depth effects on capacitances, and further increased the capacitance significantly by the composite of CoO/ADC. AC is also obtained from the bio-waste oil tea shells, the characterizations show that a certain amount of graphitic structure carbons exist, and the BET surface area is up to 2800 m2/g, using the large surface; Mno2 particles in the solution were adsorbed to form a film-like coating on the surface, a specific capacitance of 1600F/g @ 0.5A/g is achieved. An asymmetric capacitor cell is set up (MnO2/AC//AC), an energy density 24Wh/kg @275W/kg was reached, which shows great enhancement according to the published works; the details were given in Chapter 3. Carbon nanotube (CNT) is another important material for application. It possesses high electron conductivity, high thermal conductivity, large tensile strength, huge current tolerance and flexibility. All these merits are based on the growth of CNTs; in Chapter 4, we discussed about the CNT growth by 26 factorial designs; the main factor was found. The obtained CNT arrays were further pulled in yarns and doped with Au particles, which enhance the electron conductivity greatly.
