Tebogo Motsei
Tebogo Motsei, a PhD student in Physics at the UFS, has been awarded the prestigious CV Raman International Fellowship for African Researchers.

Imagine a supercapacitor/battery made right here in South Africa that could change the way we store energy for the better. A product that can store energy in real time, thus solving energy problems as they happen, which makes a huge difference especially during power outages. A product that is not just good for the environment – transitioning away from lithium-ion batteries – but that can also create jobs and boost the local economy.

What we are talking about is a type of technology known as a sodium-ion supercapacitor/battery, which is the focus of Tebogo Motsei’s research. This technology serves as a power source for lighting, power plants, cars, and phones. Motsei, a PhD student in the Department of Physics on the Qwaqwa Campus of the University of the Free State (UFS), explains that – unlike lithium batteries, which have undergone extensive research and are expensive to produce – they are conducting experimental work and characterisations to determine if sodium-ion supercapacitor/batteries can perform as well or even better, using more affordable and eco-friendly materials.

“Our results, inspired by the urgent need for improved energy storage solutions in South Africa amid its energy challenges, have been very promising. We have successfully developed a sodium-ion supercapacitor/battery that stores as much energy as a lithium-ion battery. Moreover, it was crafted from recycled materials, making it a more cost-effective and environmentally friendly option,” states Motsei, adding that their battery is unique, as no one else in the world has created anything quite like it, despite numerous attempts.

She is also pleased with this supercapacitor/battery’s ability to repair itself. Motsei explains, “Imagine if your toy could fix itself whenever it got broken – that's kind of what our sodium-ion supercapacitor/battery does!”

Motsei is part of a group of scientists in the Department of Physics at the UFS who are working on this research and who have published a scientific article on their work, titled Composite super-capacitor/Na-ion battery with self-healing Fe–Cr alloy electrodes. 

“We're proud of what we have accomplished,” she remarks.

Fellowship: a dream come true

Being part of this impactful research contributed to Motsei receiving the prestigious CV Raman International Fellowship for African Researchers (2023). The fellowship is for African researchers engaged in research at an African institution, providing opportunities for research collaboration in India. Motsei will be the only candidate from South Africa.

This award is merit-based. Motsei attributes her selection to factors such as her strong academic record, research accomplishments, and innovative approach to solving complex problems. She also believes her experience in research, collaboration, and publication reflects her potential to make meaningful contributions to the field during the fellowship period. 

Another key factor contributing to her selection for this fellowship is her skill in fabricating actual devices/prototypes. “The hands-on nature of this research, allowing me to create devices from scratch, has always been my passion. Making my first device – the ‘Magnetron Sputtering Unit’ – during my master’s studies, was a turning point. It made me realise that I had made the best decision ever by choosing this research field. I'm truly passionate about my work,” says Motsei. 

For her PhD studies, she is supervised by Prof Richard Ocaya, Associate Professor in the Department of Physics, and co-supervised by Dr Kamohelo Tshabalala, Senior Lecturer in the Department of Physics. Prof Ocaya, proud of Motsei’s achievements, believes that this fellowship not only serves as a great motivation for students – especially on the Qwaqwa Campus – but also highlights the global relevance of the UFS, particularly the Department of Physics.

Motsei says receiving this fellowship is a dream come true and a profound, life-changing moment for her. “I feel deeply honoured to be concluding this programme at the CSIR-Electrochemical Research Institute, the host institution in India, under the guidance of Prof Arul Manuel Stephan, whose invaluable assistance has been instrumental in my preparations.” Motsei also expressed her gratitude towards everyone who has supported her during this process, including Sudhir Kumar from the Indian Embassy in Pretoria.

“I am excited about how I can use this opportunity to make a difference. Whether it’s tackling significant global energy issues or finding new ways to solve everyday problems, I know this fellowship will give me the tools and support needed to make a real impact. Overall, I see this fellowship as a stepping stone to exciting new opportunities and adventures in the world of research,” she comments.

Making a meaningful impact

Motsei will be leaving for India on 23 February for a period of six months. She is excited about this new chapter in her research journey. “This fellowship will enhance my abilities as a scientist and leader in physics, providing me with essential skills, connections, and experience to make a meaningful impact in science and energy. I'm genuinely happy about this opportunity, which I thank God for.”

  • Sir Chandrasekhara Venkata Raman, after whom the fellowship is named, was a renowned Indian physicist who made great contributions to physics, winning many prizes and awards, including the 1930 Nobel Prize in Physics. He was known for his work in the field of light scattering and was the first Asian and non-European to receive a Nobel prize in any branch of science.

Moshoeshoe - lessons from an African icon - by Prof Frederick Fourie
2004-11-03

(The full text of the article that appeared in City Press and Sunday Independent)

Our understanding of history informs our understanding of the present. No wonder the contestation over historical figures in South Africa’s past is so fierce and so divisive.
The question is: could it be any other way? I would like to think that it could; that black and white South Africans, across linguistic, cultural, religious and other divides, can develop a shared appreciation of our history – at least with certain periods and personalities as a starting point.

One such personality whose legacy I believe offers a possible platform for unifying our still divided country is King Moshoeshoe, who lived from 1786 to 1870, and is acknowledged as the founder of the Basotho.

King Moshoeshoe is the topic of a documentary that has been commissioned by the University of the Free State as part of its Centenary celebrations this year. It is part of a larger project to honour and research the legacy of Moshoeshoe. The documentary will be screened on SABC 2 at 21:00 on November 4th.

Moshoeshoe rose to prominence at a time of great upheaval and conflict in South Africa – the 19th century, a time when British colonialism was entrenching itself, when the Boer trekkers were migrating from the Cape and when numerous indigenous chiefdoms and groupings were engaged in territorial conquests. It was the time of the Difaqane, a period when society in the central parts of the later South Africa and Lesotho was fractured, destabilised and caught in a cycle of violence and aggression.

In this period Moshoeshoe displayed a unique and innovative model of leadership that resulted in reconciliation, peace and stability in the area that later became Lesotho and Free State. It made him stand out from many of his contemporaries and also caught the attention of his colonial adversaries.

Such an evaluation is not a judgment about which model of leadership is right and which is wrong, or which leader was better than another; but merely an attempt to explore what we can learn from a particular exemplar.
|
Historians point to the many progressive leadership qualities displayed by Moshoeshoe which he used effectively in establishing the Basotho nation and in defending it.
First, there is his humanism and sense of justice worthy of any great statesman. Confronted by a situation in which cannibals murdered and devoured his grandfather, Moshoeshoe chose not to take revenge. Instead he opted to rehabilitate them and feed them as he believed hunger drove them to cannibalism.

Secondly, there is his skilful alliance-building with his contemporaries such as Shaka in an attempt to neutralize those rivals who were intent on attacking his followers. This is also displayed in the way he sought the protection of the British to keep the Boer forces at bay.
Thirdly, his emphasis on peaceful options is also seen in his defensive military strategy which saw him retreat to a mountain fortress to be able to protect and build a burgeoning nation in the face of the many forces threatening its survival.

Fourthly, there is his remarkable inclusivity and tolerance for diversity which saw him unite disparate groups of refugees from the violence and hunger that displaced them and then weld them into the Basotho nation. He also engaged with French missionaries, inviting them to stay with him and advise him on Western thought, technology and religion.
These are but some of the qualities which belie the notion that all 19th century African leaders were merely marauders and conquerors that gained their ascendancy through violence. Instead Moshoeshoe is a prime example of the human-centred, democratic and pluralist roots of South African, indeed African society.

The Moshoeshoe project that we have initiated (of which the documentary, called “The Renaissance King”, forms but one part) derives from our location as a university in the Free State, a province with a particular history and a particular political culture that developed as a result of this very model of leadership. This province has benefited tremendously from leaders such as Moshoeshoe and president MT Steyn, both of whom many observers credit with establishing a climate of tolerance, respect for diversity of opinion, political accommodation and peaceful methods of pursuing political objectives in the province. Their legacy is real – and Moshoeshoe’s role can not be overstated.
In addition the project derives from the University of the Free State being a site of higher learning in a broader geo-political sense. As a university in Africa we are called upon to understand and critically engage with this history, this context and this legacy.
Besides the documentary, the UFS is also planning to establish an annual Moshoeshoe memorial lecture which will focus on and interrogate models of African leadership, nation-building, reconciliation, diversity management and political tolerance.

In tackling such projects, there may be a temptation to engage in myth-making. It is a trap we must be wary of, especially as an institution of higher learning. We need to ask critical questions about some aspects of Moshoeshoe’s leadership but of current political leadership as well. Thus there is a need for rigorous academic research into aspects of the Moshoeshoe legacy in particular but also into these above-mentioned issues.
While the documentary was commissioned to coincide with the University of the Free State’s centenary and our country’s ten years of democracy, it is a project that has a much wider significance. It is an attempt to get people talking about our past and about our future, as a campus, as a province and as a country – even as a continent, given the NEPAD initiatives to promote democracy and good governance.

The project therefore has particular relevance for the continued transformation of institutions such as universities and the transformation of our society. Hopefully it will assist those who are confronted by the question how to bring about new institutional cultures or even a national political culture that is truly inclusive, tolerant, democratic, non-sexist, non-racial, multilingual and multicultural.

I believe that the Moshoeshoe model of leadership can be emulated and provide some point of convergence. A fractured society such as ours needs points of convergence, icons and heroes which we can share. Moshoeshoe is one such an African icon – in a world with too few of them.

Prof Frederick Fourie is the Rector and Vice-Chancellor of the University of the Free State
