Project 4 (currently in progress)
Acquisition, Technology and Logistics Agency/Security Technology Research Promotion Program
February 2023 to March 2027
"Elucidation of the charging and discharging mechanism of organic positive electrode secondary batteries and research on high energy density"
Rechargeable batteries are indispensable for the efficient use of energy, and active research and development is being carried out around the world on high-energy technology that charges and discharges more energy. We have developed pressurized electrolysis pre-doping technology that reduces the irreversible capacity of lithium-ion secondary batteries, and have succeeded in prototyping high-energy small drone batteries and large drone batteries. In the project, which will start in October 2022, we will develop practical technology that enables continuous pressurized electrolysis pre-doping that can be used industrially, and conduct research and development for practical application of secondary batteries for drones that can fly for a long time. .

"Technology of high-energy batteries for large drones by continuous electrolytic pre-doping technologytechnology development
In 2020, NEDO's research and development startup support project (NEP B) developed a secondary battery that extended the flight time of drones by 1.7 times by using pressure electrolytically pre-doped Si negative electrodes, and conducted a demonstration test. was successful. The cell prototyped in this project has a capacity of 1.7 Ah (energy 6 Wh) and can take off and fly small drones and micro drones. However, long flight time is strongly desired even for large drones.
NEDO Project 2, which will start in October 2021, will develop batteries for large drones using the high-energy battery technology developed and demonstrated in NEDO Project 1 until September.
By increasing the size of high-energy batteries, the flight time, flight distance, and transport weight of large drones will increase, making the industrial drone sky industrial revolution starting in 2022 more valuable.
In this project, proven high-energy battery technology using high-capacity Si anodes will be applied to large cells as they are.
We plan to develop high-energy batteries for large drones and confirm their effectiveness toward the completion of the project in September 2022. We would like to proceed with development while exchanging information with everyone who needs high-energy batteries. If you are interested, please contact us.
Project 1
NEDO Research and Development Startup Support Project NEP B (October 2020-September 2021)
"Development of safe and long-flight infrastructure inspection drone batteries"
In 2020, ORLIB Co., Ltd. was adopted by the New Energy and Industrial Technology Development Organization, a research and development type start-up support project (NEDO NEP B), and is scheduled to run from October 2020 to September 2021. We are developing a secondary battery for infrastructure inspection drones that can fly for a long time.
In this project, we want to show that the new battery is a battery that can actually be used, and to prove that it is not a vague idea or simulation, but a reality.
Assuming that a high-energy battery has been developed, it is important to consider "what is the application that needs this battery most?" We chose batteries for drones, especially batteries for infrastructure inspection drones.
Drones that fly while controlling the output at short intervals using multiple motors are expected to be used in various ways. However, due to the large proportion of the weight of the battery in the entire aircraft, the maximum flight time is limited to about 20 minutes (some types with wings can fly for about an hour, but hovering time is still limited). 20 min).
By the way, Japan has a lot of infrastructure, and the number is more than 260,000 (Road and Railway Statistical Yearbook). Regular inspections are stipulated, but there are many difficulties such as scaffolding and crane trucks, and efficient inspections were required. Therefore, the use of drones was considered, but there was a problem of flight time. For example, in the figure on the upper right, if you use a drone that can fly for 20 minutes to perform a visual inspection, if it takes 5 minutes to reach the inspection site, it will take 10 minutes for the round trip. As a result, the time required for on-site inspection is reduced to only 5 minutes.
For this reason, until now, it was necessary to bring a lot of batteries and inspect them while replacing them. If the high-energy battery we develop is applied to this application, the flight time will be doubled, the inspection time will be five times longer, and the efficiency will be greatly improved.

Towards the end of the project, in September 2021, we will conduct a demonstration flight of a drone equipped with a high-energy battery in the presence of an infrastructure inspection manufacturer, confirming that it can actually be used and that it is superior to conventional batteries. will be shown.
Please look forward to the results of the project.
