Nkahiseng Ralepeli will join the Rhodes Scholarship cohort of 2019.

Aspiring lawyer and political prodigy, Nkahiseng Ralepeli, will soon join a cohort of Rhodes Scholarship recipients at the University of Oxford in the UK later this year. He completed his LLB at the University of the Free State (UFS) in 2018, and it comes as no surprise that this young achiever has his eyes set on greater heights.

As a student, Nkahiseng was always a cut above the rest, with his involvement in non-governmental organisations such as Corruption Watch and Debate Afrika, where he used debating to not only educate youth in South Africa but to engage various social ills that plague the country in whichever way he could. He represented the UFS at various debating tournaments such as the Pan-African Universities Debating Championships and the World Universities Debating Championships.

“This is something I’ve wanted for an incredibly long time. Receiving this scholarship is so important, and makes me feel that all my efforts and work have been validated. What I’ve learned is that regardless of the situation you’re born into, rich or poor, hard work is rewarded. I hope this experience will help me realise my dreams and career goals, but most importantly I want to have a significant impact in whatever space I find myself in and on the people I encounter,” said Nkahiseng.

As an Abe Bailey Bursary recipient, he is deeply interested in the transformation of African political theory and the establishment of various structures in the development and maintenance of African ‘infant’ democracies and post-civil wars. He later hopes to pursue a career in South African politics. His list of achievements keeps getting longer as he adds to it the Rhodes Scholarship. The UFS is truly proud to have an alumnus of this high calibre.

Lithium-ion batteries research set to improve ordinary lives
2016-02-11

Description: Dr Lehlohonolo Koao  Tags: Dr Lehlohonolo Koao

Dr Koao is making a much-needed contribution in improving lives of ordinary people through his research on lithium-ion batteries.

The future of relevant and top-notch scientific research at the Qwaqwa Campus is in good hands. Dr Lehlohonolo Koao is one of the five members of the Vice-Chancellor’s Prestige Scholars Programme (PSP) on the Qwaqwa Campus.

The need to improve the efficiency of heating mechanisms in his immediate community in Qwaqwa, and the support he receives from the PSP, have become catalysts for his current research project on lithium-ion batteries. According to Dr Koao, the study will focus on producing batteries that last longer, store more energy, are cheaper to manufacture, and are environmentally friendly when being disposed of. These are key factors in solar energy.

‘’The majority of households in my neighbourhood have benefited from the government’s project of providing households with solar panels to help with lighting, cooking, and heating without worrying about the ever-increasing electricity costs,’’ said Dr Koao.

‘’Since my arrival in the area, I have realized that the heat absorption rate of the batteries used by solar panels is not enough. As a result, these batteries also lack enough power to sustain the supply throughout the day, especially on a cloudy day,’’ he said.

His research project focuses on improving the efficiency of lithium-ion batteries that are now commonly used in portable electronics, such as cell phones and laptops. This kind of battery is rapidly replacing the usual lead-acid batteries. Dr Koao’s determination to contribute towards a safer and more efficient heating absorption system has made him move away completely from his PhD study on lighting material.

‘’My previous study was on reducing the power usage on domestic and industrial lights as they use more electricity. This study, on the other hand, will enhance power retention in the batteries for improved daily life since cell phones, solar panels, and laptops, to mention only a few, are now a way of life,’’ he added.

Dr Koao is a Senior Lecturer in the Department of Physics, where he specializes in solid state materials.
