Assoc. Prof. Dr. Kittichai Triratanasirichai, Khon Kaen University President with Prof. Dr. Supachai Patumnakul, Vice President for Research and Technology Transfer; Assoc. Prof. Dr. Supawatanakorn Wongtanawasu, Dean of College of Local Administration, Asst. Prof. Dr. Somkiat Srijaranai, Dean of Faculty of Sciences, lecturers and staff members welcomed the 20th class of Thailand National Defense College (TNDC) led by Lieutenant General Pariphat Phalasin the College’s Director, who came on a study trip to see the use of nano-materials energy from plants to produce lithium battery by synthesizing rice husk ashes on January 12, 2018 at Peerasit Kamnuansin Room, College of Local Administration.
Assoc. Prof. Dr. Kittichai Triratanasirichai first gave an welcoming address to the administrators and students from Thailand National Defense College and thanked the Director who honored KKU by joining this visit. The President continued to present the overall background and roles of KKU towards the Northeast communities, and explained the innovative research works that will help drive the country towards Thailand 4.0.
Then Asst. Prof. Dr. Nonglak Meethong, a lecturer of Department of Physics of Khon Kaen University, who represented the Nano-Technology Research and Integration Center explained about the research work that received the young scientist award of 2015: “Nanomaterials from plants obtained by synthesizing nanomaterials such as nanosilica, nanosilicon, and carbide from husk ash could be used in place of carbon, which is the raw material for producing anodes or cathodes of lithium –ion batteries. This kind of battery can retain 12 times more energy than carbon. Lithium –ion batteries are also small and light and have a capacity to retain the greatest amount of energy when compared to other ionized batteries.
Presently, the batteries are used in different electrical appliances as well as cars and motorcycles. Asst. Prof. Dr. Nonglak Meethong revealed that one cart of rice husks can yield 250 kg of ashes. After the process, the amount reduces to 40 kg. Theoretically, further process makes 20 kg of nanosilicon, but in practice, it reduces to only 2 kg because of loss. If the power is used in an electric car, 5 kg of silicon is needed or 2-3carts of rice husk, or 7100 batteries are required of the sizes 85mm and 16mm. This is the first nanosilicon produced from ashes to produce batteries for a motorcycle.
Lieutenant General Pariphat Phalasin, Director of Thailand National Defense College (TNDC) said, “We are very happy with the innovation of Khon Kaen University. The objectives of this trip are to survey the surroundings in the area to assess chances, drawbacks and advantages, to study the weakness and strength, to study the strategies and the nation’s power and use the information to make a proposal for supporting the 20-year strategies of the Government. This is a very important task. Besides, we will use the information for research work and we will report the result to you. We really appreciate Khon Kaen University. The students and the teachers all agree that KKU is the most appropriate place for our study trip.”
Khon Kaen University meets the needs of the region and the neighboring countries in terms of educational chances at university level. KKU helps in mitigating the poverty of the people. In terms of students, they are well taken care of from the strategies given be the late King, “Understand, access, and development.” This is used for instruction in the university. Students learn from practices so that they can hold an occupation. Mr. Preecha Wechasat, Direcotr of Pattani’s Fishery and Agricultural Technology College was the representative of the students of TNDC also expressed his feeling at the end.
