World’s first graphene-applied lead-acid battery mass produced in Sri Lanka


Graphene is the world's thinnest substance, and its interesting features have made it popular. "Graphene, for example, is 100 times stronger than the finest steel and 100 times stronger than diamond. It is durable, adaptable, and transparent. It is utilized to produce miniaturized, super-fast computers and transistors because it conducts so much electricity in such a small space."

In 2017, mining and quarrying contributed roughly 2.7 percent of Sri Lanka's GDP. "Graphene is renowned as the world's newest breakthrough substance, and increased exports might treble present export revenue." Sri Lanka is the only country in the world that produces vein graphite, which has been mined for over two centuries and is called locally as 'Miniran.'


For more than a century, Sri Lanka has been the world's only country to harvest ultra-pure extremely crystalline vein graphite with more than 98 percent carbon purity. Currently, Sri Lanka produces only 300 tons of graphite per month. Graphite in Sri Lanka is mostly produced from three mines: Bogala, Kahatagaha, and Ragedara. "Graphite from these mines can be harvested for another century, and Sri Lankan graphite is globally famous for its excellent quality and originality.


Ceylon Graphene Technologies Ltd is Sri Lanka's first graphene and advanced materials company, and it is currently looking to expand its value-added graphene exports in order to become the country one of the world's leading graphene producers.

This technology is ready for mass production and will be accessible on the market in the near future. The graphene and its derivatives outcome optimization is likely to be further modified, and substantial study is currently underway.


Graphene export is merely the first step. Their factory in Homagama will be fully operational as soon as possible. "This will assist us in increasing exports and manufacturing things for export such as vehicle batteries, computer processors, and solar power products." In addition to coatings, paints, and plastics, graphene additions are employed in automotive applications.


With the goal of making the country a global leader in graphene production. CGT has developed a new and sustainable graphite refining process in collaboration with SLINTEC that can create graphene from locally mined graphite at a lower cost. "The government, too, wants to see mining's share of GDP rise, and they're working on it."

The collaboration with Associate Battery Manufacturers to launch the first ever Graphene applied Lead Acid Battery has been one of CGT's success stories for the past one and a half years.

CGT has also attended numerous events and exhibitions across the world to promote and share our technology and knowledge, as well as to explore new business opportunities."

-SriLanka for reason.

Oldest Radio Station in Asia (world’s second oldest)-Radio Ceylon - Srilanka

Sri Lanka possesses Asia's (and the world's) oldest radio station. Radio Ceylon used to be the name of the station. It grew into one of the world's most prestigious broadcasting institutions. The Sri Lanka Broadcasting Corporation is now the name of the company. When the Telegraph Department began broadcasting in Ceylon on an experimental basis in 1923, just three years after broadcasting in Europe, Sri Lanka made Asian broadcasting history. A modest transmitter created by Telegraph Department engineers using the radio equipment of a captured German submarine was used to broadcast gramophone music from a tiny chamber in the Central Telegraph Office. This radio trial was a big success, and a regular broadcasting service was established only three years later, on December 16, 1925. Edward Harper, who arrived in Ceylon in 1921 as Chief Engineer of the Telegraph Office, was the first person in the country to actively push radio. With broadcasting services launched just thre...

World's first female prime minister - Honorable Sirimavo Bandaranaike.

Following the killing of her husband, Sirimavo Bandaranaike was elected as the world's first female Prime Minister on July 21, 1960. She promoted principles of nonalignment abroad and democratic socialism at home. Following her husband's killing, Sirimavo Bandaranaike became the world's first female Prime Minister on July 21, 1960. She promoted nonalignment policies both overseas and at home, as well as democratic socialism. Sirimavo (sometimes Sirima) Ratwatte Dias Bandaranaike was born on April 17, 1916, to an aristocratic Kandyan family and educated in a Roman Catholic convent in Colombo. Bandaranaike married Solomon West Ridge-way Dias (SWRD) Bandaranaike in 1940, when he was a minister in the government of Ceylon, then a British crown territory. Bandaranaike's life was politically unremarkable. She had the preoccupations of a homemaker married to an important national leader who became Ceylon's prime minister in 1956, eight years after independence. However, SW...

The oldest human planted tree in the world - JAYA SRI MAHA BODHI

The oldest tree known to have been planted by humans rather than natural sowing is a 2,300-year-old sacred fig or bo-tree (Ficus religiosa) in Anuradhapura, Sri Lanka, known as Sri Maha Bodhiya. It was planted there around 288 BC. The mother tree from which this specimen was reproduced was none other than the famed Bodhi tree, under which Siddhartha Gautama, the Lord Buddha, sat when he attained enlightenment. Naturally, because of its spiritual importance, the Jaya Sri Maha Bodhi holds a special place in the hearts of the world's Buddhists, particularly those in Sri Lanka. Every year, Buddhists from all over the world come to visit and pay their respects to one of the most precious ancient relics of the Buddhist faith. According to history, Sangamitte Theri, daughter of Emperor Asoka, transported the tree all the way from India to Sri Lanka in the 3rd century BC. Sangmitta established her own order of Buddhist nuns in her native Sri Lanka. The tree was then officially planted by K...
