Description:
FIELD OF INVENTION 
       [0001]    Embodiments of the present invention relates to a class of tungsten trioxide material for electrochemical energy storage and conversion devices, including the design and synthesis of electrode materials, design and manufacturing of the electrode and the cell structure, as well as design and manufacturing of other related components. More particularly, the invention relates to chemistry, chemical engineering, energy material sectors. 
       BACKGROUND 
       [0002]    The present patent application relates to design and manufacturing of a class of high-performance battery and supercapacitor (referred as a super battery in the whole context of patent). With the rapid development of industrialization and the global economy, worldwide energy consumption has increased steadily, which inevitably leads to the increasing depletion of fossil fuels and deterioration of the environment. 
         [0003]    Exploring renewable energy sources (such as solar, wind and tidal energy), and also improving efficiency of energy use, for example, the use of electric or hybrid electric vehicles to replace the traditional internal combustion engine vehicles, have become the main strategy to solve the energy crisis. 
         [0004]    Therefore, to develop easy, stable electrochemical energy storage devices with fast power delivery capability becomes increasingly urgent. Facing this challenge, sustainable, low pollution electrochemical energy storage devices will be the core technology for supporting modern civilization. 
         [0005]    Batteries and supercapacitors are commonly used electrochemical devices for portable electronics, electric vehicles, renewable energy storage, and other applications. Commonly referred electrochemical energy devices mainly include lead-acid batteries, nickel-cadmium (Ni—Cd) batteries, nickel-metal hydride (NiMH) batteries, lithium-ion batteries and supercapacitors. Due to their low cost and reliable safety property, lead-acid batteries have been widely used for more than 150 years. However, lead-acid batteries have short cycling life and low power density. By comparison, Ni—Cd batteries have slightly improved power density and cycling life but with increased cost and toxicity. Comparing with the previous two types of batteries, NiMH batteries have significantly higher energy density, but their cycling life is still short and cost has been increased dramatically in the recent years due to the increased price of rare earth metals. Because of their high energy density, low self-discharge and long cycling life, lithium-ion batteries are so far the most widely used rechargeable batteries. However, the costs for lithium-ion batteries are high due to the need of scarce lithium and strictly controlled manufacturing process. And more importantly, since organic electrolyte is used in the lithium-ion battery, the safety property is poor, which is unfavorable for large-scale application such as EVs and grid-storage. 
         [0006]    Compared with battery, supercapacitors can provide higher power density and longer cycling life, but their energy densities are too low to be used in large-scale storage. Although using organic electrolyte can provide improved energy density of supercapacitors, the cost is largely increased and the use of electrolyte also poses similar safety concern to lithium ion batteries. 
         [0007]    There is therefore a great demand in developing safe and low cost electrochemical energy storage devices with significantly improved power density, energy density, and cycling life. Besides the too high cost, in the aspect of safety, currently used energy storage systems are problematic due to the use of highly flammable organic electrolytes, which cannot meet the safety requirement for applications. Aqueous-electrolyte-based energy storage devices, such as lead-acid batteries, Ni—Cd, and NiMH batteries, are non-flammable and safe in case of accident and other mis-operation situations. Therefore, improving the performance of aqueous-electrolyte-based energy storage devices can lead to highly safe, low-cost devices for transportation, stationary energy storage, and other broad spectrum of applications. 
         [0008]    Among the aqueous-electrolyte-based systems, lead-acid batteries that are highly reliable and low cost are of particular commercial interest. To date, extensive efforts have been made to improve the performance of lead-acid batteries, such as making better electrodes with controlled composition and structure, using gel-like electrolyte and fibrous separation membranes. Despite such extensive efforts result in increased performance to some extent, overall it is thus far still difficult to fabricate lead-acid batteries with high enough power density and lifetime as required by many industrial applications. 
         [0009]    In the recent years, lead-acid super-batteries were developed with significantly improved power performance and lifetime. This was mainly achieved by completely or partially replacing the traditional anode materials (Pb) and/or cathode materials (PbO 2 ) with porous carbons. The prior arts in such super-batteries were described in a series of patents (KR1020060084441A, CA2680743, CA2680747, CN200910183503). Despite the improved power density and lifetime achieved, in comparison with the energy density of lead-acid batteries (40-50 Wh/kg), the cost is that the energy densities of such super-batteries are dramatically reduced (8-16 Wh/kg). The incorporation of carbon materials into electrodes inevitably leads to mismatched electrode potentials and low capacity. 
         [0010]    Compared with the carbon material, metal oxide material can provide higher capacity. Therefore, an appropriate use of metal oxide can provide lead-acid super batteries with higher energy density. More studied oxides include manganese oxide, ruthenium oxide, iron oxide, et al nickel oxide, but there very limited oxides that are suitable for acidic electrolytes. Although ruthenium oxide can work in an acidic electrolyte, but its cost is extremely high and not suitable for large-scale industrial applications. Moreover, since its working voltage is above zero volts (compared to silver/silver chloride electrode), it is not suitable to construct lead-acid super batteries. Tungsten oxide material has excellent electrochemical stability in acidic solution, but so far there is very little research on its energy storage properties. Lee et al. (Chem Commun., 2011, 47, 1021-1023) reported the electrochemical properties of high-temperature-sintered tungsten oxide based on porous silica as hard template. Its working potential ranges from −0.2 to 0.8 V, but its capacity is low. Wang et al. (Adv. Energy Mater., 2012, 2, 1328-1332) reported tungsten oxide material grown at 1080° C. as a supercapacitor structure material, which has stable electrochemical properties in neutral sodium sulfate electrolytic solution. Lu et al (Carbon, 2014, 69, 287-293) reported the electrochemical properties of a simple tungsten oxide/carbon aerogel composite based on the lower temperature synthesis with single electrode, the operating voltage window also quite narrow (−0.3 to 0.5 volts), and therefore the capacitance is low. While these works reported the possibility of using tungsten oxide material as an energy storage material in acidic electrolytes, they did not establish an efficient full battery system. In addition, combining oxide material and lead material to construct an energy storage device has failed to report or proposed now. 
         [0011]    Insofar as we are aware, no lead-acid storage devices formerly developed can provide high enough power and high energy density, as well as long enough lifetime, that are required by many industrial applications. 
       Disclosure 
       [0012]    With the rapid development of modern industrialization and human civilization, human&#39;s demand in high efficiency, safe and low-cost energy storage technology continues to grow. Because lead-acid batteries have unique advantages, they are still based on the modern industry and have a great prospect in many applications. 
         [0013]    However, improvements towards lead-acid battery materials, structure and technology are still unable to break through the bottleneck that limits its performance to improve, making it impossible to meet the needs in the field of large-scale energy storage and power supply.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0108]    The following examples further illustrate the invention, but the present invention is not limited to these examples.

In these super battery systems, the negative electrode material is selected from the aforementioned tungsten-containing active materials, and the tungsten-based materials can be used as negative electrodes together with carbon or lead-based material. 
         [0110]    As described above, the use of tungsten-based active material include tungsten oxide, hydrous tungsten oxide, element-doped tungsten oxide, element-doped hydrous tungsten oxide, tungsten oxide-based composite and mixtures comprising the foregoing tungsten-containing materials and carbon, polymer materials, metals and ceramics and mixture of these materials. Details of the following contents introduce the structure and construction method and such tungsten-based super batteries. 
       1. If the Electrochemical Energy Storage and Conversion Device is Tungsten Carbon-Based Super Battery: 
       [0111]    The first type of super-batteries of the present invention is depicted in  FIG. 1 ,  FIG. 2A ,  FIG. 2B ,  FIG. 2C , and  FIG. 2D . This type of super-batteries uses tungsten-based materials as the anodes, such as pure tungsten materials, mixture of tungsten materials and lead, and mixture of tungsten materials and carbon; uses the same tungsten-based materials or porous carbons as cathodes. The super batteries described in the present invention can provide high power density, super long cycling life and considerable energy storage density. 
         [0112]    Super battery shown in  FIG. 1  includes a cathode current collector  2 , an anode current collector  3 , tungsten-material-based negative electrode  4 , a porous separator  5 , high surface area carbon or the same tungsten electrode as a positive electrode  1  and electrolyte filling in between. Wherein, the separator may be a variety of stable and insulating porous membranes such as glass fiber, nonwoven fabric, etc. The membrane plays the role of isolating positive and negative electrodes; the current collectors required for the preparation of electrodes may be various stable and electronic conductive substrates, such as carbon felt, titanium foil, lead grid, etc. They play a role in the collection and conduction electrons. The electrolyte can be various aqueous or organic solutions containing sufficient electrolyte ion concentration and a high ionic conductivity; preferred electrolyte is aqueous electrolyte containing a sufficient concentration of protons, such as sulfuric acid, phosphoric acid, perchloric acid, etc. It plays a role of providing protons. The carbon material for positive electrode may be a variety of porous carbons, which could be selected from activated carbon, carbon nanotubes, carbon nanofibers, graphene or other porous carbon sources. It provides an electric double layer capacitance in the super battery. 
         [0113]    Those skilled in the art can readily understand that the tungsten-based active materials in the present invention may be synthesized by different methods, and the material is then processed into a powder to prepare electrodes. The specific synthetic methods, as an example, will be described in detail below. 
         [0114]    In the present invention, the method of using tungsten-based materials in the tungsten-carbon-based super battery is to take the as-prepared tungsten-based active material in the powder form, conductive agent, a binder and a dispersing agent to formulate into a uniform electrode slurry, and then apply the electrode slurry onto the current collector to form the tungsten-material-based anode, the specific preparation method, as an example, will be described in detail below. 
         [0115]      FIG. 2  also shows a tungsten-carbon super battery. The super battery structure comprises tungsten-based and lead-based anode material, separator, high surface area carbon cathode and electrolyte.
