 [Six major spindles]

Hi-GEM specifically integrates domestic academic materials such as materials, chemicals, motors, optoelectronics, physics, and industrial design. It includes six major spindle projects, such as (I) all solid-state batteries, (II) secondary batteries, (III) super capacitors, and (IV) solar cells (V) fuel cells, and (VI) industrial links to achieve the goal of China's key green energy material autonomy. At the same time, based on solid core technology, including the development and upgrading of new photoelectric active materials, the development of electrode materials, modification and interface, as well as the improvement of ion conductivity and stability of electrolyte materials are the major goals to achieve. By mastering the common core technology of key components, we can develop novel green energy materials and apply them to various energy-generating and energy storage green energy components. In terms of industrial impact, the company will implement the central contribution of the center to the country and industry with two commercialization strategies such as product design and industry spillover.

[Key materials development]

National Cheng Kung University is ranked 19th in the “Alternative Energy Field” (Elsevier), and 26 members of the Center are highly efficient in the field of green energy materials. Enhancement of the "key material autonomy rate" as the technical dilemma needs serious improvement. The Center plans to use the material genetic method of cross-scale calculation of materials to achieve green energy key material design, develop adhesive solid electrolyte, high performance and high stability electrode material, key green energy materials such as photovoltaic active materials, development of energy storage equipment, power management systems and creative battery design. The following is a brief description of the four component industry technologies.

 

Lithium-ion solid state battery industry technology


At present, the car manufacturers all over the world are trying to develop high-safety lithium-ion solid-state batteries. The solid electrolyte materials of the polyetheramine polymer series developed by the team members of the center can be developed into high-safety lithium ion secondary batteries. It will cooperate with LTO/NMC batteries of ITRI and cooperate with battery manufacturers to develop colloidal electrolyte equipment and inorganic garnet type Li6.2La3Zr1.8Al0.2Ta0.2O12 (LLZO) solid electrolyte. This solid electrolyte had an ionic conductivity of 10-4 S/cm at room temperature. The introduction of a polymer at the interface between the inorganic ceramic electrolyte and the cathode (LiFePO4) and the anode lithium metal can reduce the ion conduction resistance between the interfaces. The optimized inorganic polymer synthesis ratio, the inorganic ceramic-GPE composite electrolyte has a discharge capacity of 165 mAh/g at room temperature of 0.05 mA/cm2, which is a major breakthrough.

Lithium ion battery material industry technology

Based on the development of green energy, the EU, the United States and other countries urgently need to replace lead-acid batteries, so these regions have a huge energy storage market and we have the opportunity to carry out commercial evaluation of performance-qualified electrolyte materials through the implementation of the plan. The research team of the center has successfully developed a high specific capacity battery carbon anode material, and improved the shortcomings of volume expansion during the charge and discharge process of lithium ion migration (generally > 300%). After one charge and discharge, the capacity is only lost by 30%, and it is almost no longer lost in the subsequent charge and discharge process. At present, it has reached an industry-university cooperation with Sinosteel Carbon Co., Ltd., and will jointly carry lithium-ion research for electric vehicle platforms. Development of battery and carbon anode materials, and through the Ministry of Education, “Building a research and development plan for the development of the university's new research and development service company,” will use the experience of the powder production of Sinosteel Carbon Co., Ltd. to improve the relevant process, technology the establishment of a new company, SiLican Co., Ltd. (SiLican). On the other hand, we also plan to develop a layered cathode material that is stable and free of cobalt when it is high in SoC and related lithium ion battery cathode material technology, and develop secondary battery electrolyte screening machinery learning related technology. Python programming language is also used to learn and predict the electrolyte-like reduction properties of different structural molecules in the LIBs.

Solar cell industry technology

In the dye-sensitized solar cell technology, the short life time and the mass production are the major issues in the industry due to the use of liquid solvents. The research team of the center is developing the colloidal electrolyte materials and applying them to the photoelectric conversion of solar light sources and indoor environments. In the development of colloidal electrolytes, the team used the choice of polymer materials to innovate the production of printed colloidal electrolytes to improve the difficulty of traditional colloidal electrolyte perfusion. The development of this printed electrolyte can also improve the production process of the traditional DSSC, which can be applied to the development of future role-to-role production procedures, which is expected to be of great benefit to the production of DSSC; The photoelectric conversion efficiency of the new-type perovskite solar cell developed by the team members of the center is leading the world. The conversion efficiency of the 2D/3D hybrid perovskite solar cell is 19.1%, and the conversion efficiency of the Porphyrin HTM perovskite solar cell is 19.4. % is the highest efficiency in perovskite solar cells currently using Porphyrin HTM

Fuel cell industry technology

The center team successfully developed the nanotechnology of fuel cell materials, and improved the electrode materials by optimizing the electrode materials with the concept of composite materials to improve SOFC performance and cycle stability. This not only reduces the polarization resistance (< 0.3 Ω*cm2) and operating temperature of the high-temperature fuel cell, but also increases the power density of the stack component (5x5~10x10 cm2) from 700W/cm2 to 800W/cm2, and the power generation of the modular battery. It can be advanced from 50W to 60 W.
