Recently, Japan's New Energy Industry Technology Development Organization (NEDO) announced that under the framework of the "Green Innovation Fund", it will invest 151 billion yen to start the "Next-generation battery and motor development" project, aiming to promote the development of the automobile industry to electrification and reduce the total cost of electricity. Industrial chain carbon emissions to achieve carbon neutrality goals. The implementation period of this project is from 2022 to 2030. Currently, 18 projects in 3 themes have been confirmed to be funded. The details are as follows:
1. Research and development of high-performance batteries and materials
The theme will develop high-capacity batteries (such as all-solid-state batteries) and their materials with an energy density of more than 2 times current levels, i.e. over 700-800 Wh/L. At the same time, develop materials and low-carbon manufacturing processes to replace cobalt, graphite, etc. 10 topics are planned to be funded: ① Development of next-generation all-solid-state batteries; ② Establishment of a trial production line for stacked soft-pack all-solid-state batteries (ASSB) to produce high-performance batteries with low life cycle emissions; ③ High-performance solid-state electrolytes and material surface treatment Technology to develop advanced solid-state batteries; ④Increase the capacity of liquid lithium-ion batteries, develop cobalt-free cathodes and high-density filled battery designs; ⑤Develop high-capacity liquid lithium-ion batteries, cobalt-free cathodes and high-performance anodes; Develop high-capacity full-resin batteries based on the performance of resins; ⑦Research on large-capacity material composition/particulate property control, surface treatment technology, and low-emission manufacturing processes; ⑧Using vacuum evaporation technology to develop thin-film lithium metal anode manufacturing technology for all-solid-state batteries;⑨ Development of large-scale manufacturing technology for solid electrolytes with controllable particle shape; ⑩ development of ultra-high ionic conductive polymer materials for all-solid-state batteries.
2. Development of battery recycling technology
The theme will develop recycling technologies that can recover 70% lithium, 95% nickel, and more than 95% cobalt. Plan to fund 4 topics: ①Develop dry and wet combined smelting technology to improve recovery rate and reduce costs; ②Develop wet detoxification pretreatment and metal recovery technology; ③Develop non-calcined material separation and recovery and cathode material direct recovery cycle Utilize technology; ④ Develop and recycle specific electrode material technology to reduce life cycle carbon emissions.
3. Development of high-efficiency, high-power-density motor systems
The theme will develop innovative materials, motor structures, inverters, cooling technologies to improve motor system efficiency (average system efficiency up to 85%), reduce size and weight, and increase power (system output power density up to 3 kW/kg) . Plan to fund 4 topics: ①Develop high-efficiency motor systems, including the development of lightweight and high-efficiency super-multi-pole motors, high-performance inverters, high-efficiency lightweight magnetic materials, etc.; ②Develop high-efficiency and high-power density technologies for motor systems, including lightweight technology, heat dissipation technology, control technology, etc.; ③ Realize smaller size, light weight, high output density and efficient traction motor through induction motors that do not use magnets; ④ Use dysprosium-free magnets and high-performance gear steel to develop high-output, Compact, lightweight and efficient electric vehicle axles.
