Samsung Group, based in South Korea, is a multinational conglomerate company involved with electronics, mobile phones, displays (LCD, Plasma and OLEDs), materials, insurance, finance, advertising, heavy industry and more.
Samsung is researching graphene and it's the company with the most graphene related patents in the world. Samsung is also invested in XG Sciences and the two companies are co-developing graphene-enhanced batteries technology.
The latest Samsung graphene news:
Samsung may be in the race to develop a graphene-based alternative to lithium-ion batteries for its phones. Rumors are going around claiming that the Company hopes to have at least one phone with a graphene battery ready next year or by 2021.
The word is that these graphene-based batteries will be capable of a full charge in under a half-hour, but they still need to raise capacities while lowering costs. In 2017, Samsung said its researchers developed a "graphene ball" material that enables five times faster charging speeds than standard lithium-ion batteries.
XG Sciences, a US-based developer and producer of graphene flakes, has announced its plan to invest millions in expanding its Lansing-area facilities. The company will start operating out of new 64,000 square-foot facility in Vevay Township in March.
The company was formed in 2006 based on work out of Michigan State University. The company's technology can be used in automotive batteries and as wire coatings in electronics to prevent microchips from overheating. Some of the material has been used in Samsung phones as a thermally conductive adhesive, said current CEO Philip Rose. Rose also said the expansion marks the first phase in a move toward larger scale commercialization for the company.
Samsung has announced the development of a unique "graphene ball" that could make lithium-ion batteries last longer and charge faster. In fact, Samsung Advanced Institute of Technology (SAIT) said that using the new graphene ball material to make batteries will increase their capacity by 45% and make their charging speed five times faster. It was also said that batteries that use graphene ball can maintain a temperature of 60 degrees Celsius that is required for use in electric cars.
SAIT's team used a chemical vapor deposition process to grow a graphene–silica assembly, called a graphene ball. Each graphene ball is composed of a SiOx nanoparticle center and surrounding graphene layers, constituting a 3D popcorn-like structure. The graphene-ball coating improves cycle life and fast charging capability by suppressing detrimental side reactions and providing efficient conductive pathways.
Samsung collaborates with Sungkyunkwan University to develop amorphous graphene synthesis technology
A joint research conducted by Samsung Advanced Institute of Technology and Sungkyunkwan University in Korea yielded an original technology for synthesizing amorphous graphene. Amorphous graphene is a material with different properties than crystalline graphene. It has lower conductivity and according to the researchers it can be suitable for various industries including desalination.
The team stated that “the latest achievement is significant in that it has expanded the range of two-dimensional materials”, “It will be possible to discover new areas of application by utilizing the new characteristics of the amorphous material.”
In June 2015, researchers at the SAIT (Samsung's Advanced Institute of Technology) found a way to prolong the life of the standard lithium-ion batteries by using a new silicon cathode material "coded with high-crystalline graphene". Recent talk around the web suggests that this discovery may find its way to Samsung's Galaxy S7 and grant it a 5-day battery.
While the research is indeed impressive, and will hopefully be integrated in actual products in the future, it is important to say that we have no real indication that Samsung is close to commercializing their findings. Since the S7 is not scheduled for release until March 2016, there's still time for surprises...
