Patent for innovation in rechargeable batteries for the Intec

The Technological Institute of Santo Domingo (Intec) obtained a new invention patent for the creation of a technology for the manufacture of rechargeable lithium-ion batteries, that improves its efficiency up to 95%, which makes it more efficient and sustainable both the manufacture and the performance of multiple equipment that use this type of energy source.

It is a frontier innovation developed by physicist and research professor Melvin Arias, with a large potential impact on the global energy industry, in sectors such as mobile telephony, electric cars and accumulators to promote renewable energy. The National Intellectual Property Office (Onapi) granted Intec the patent P-2019-0245 for the development of the “Positive particle electrode for secondary battery and its manufacturing method based on a nanofiber membrane structure”, which offers a More effective solution than those investigated so far, to improve storage systems for rechargeable lithium, sodium or magnesium ion batteries and satisfies market requirements for a range of small, medium and large scale products and equipment.

Researchers Alina Mari De los Santos Torres, Lorenzo Caputi and Noel Alfonso Upía De la Rosa participated together with Professor Arias.


The patent was received by the vice-rector for Research and Bonding of the university, Víctor Gómez Valenzuela, who highlighted that the device and its manufacturing method are part of a family of intellectual property products developed almost ten years ago at the Nanotechnology Laboratory of the Intec within the framework of a project financed by the National Fund for Innovation and Scientific and Technological Development (Fondocyt) of the Ministry of Higher Education, Science and Technology (Mescyt). The Vice-Rector for Research and Linkage pointed out that the search for energy storage solutions is the “holy grail” of research in the sector, which in turn impacts large industries. “In fact, companies such as Toyota, Tesla, IBM among other giants worldwide, invest large resources in research to obtain batteries of greater duration and efficiency.” Researcher Melvin Arias, upon receiving the patent certificate, said that it represents a significant advance for the Dominican Republic. “This is not a random product or one that occurs randomly, but rather a process that has been developed at Intec for more than ten years, with slow and systematic work that began in 2009, when the university embarked. in a project to develop nanomaterials that could be used to replace the materials used in electronic storage devices ”, he revealed.

Arias noted that the energy storage capacity of these batteries far exceeds those of traditional batteries. Besides that they are more resistant to the increase in temperature.

He added that this patent has a solid basis in pure science, but is research applied to the solution of local and global problems. In addition, during its development the team has produced various scientific articles or papers, which also positions the Dominican Republic in a prominent place for research in nanotechnology and physics.
