For now, the progress of battery technology in electronic equipment is not yet matched with the speed of upgrading other components of the equipment. However, a technology company called Dongxu Optoelectronics hopes to change the status quo. They have recently demonstrated a The brightest battery technology. Dongxu Optoelectronics stated that they have developed the world's first graphene battery and named it G-King, with a capacity of 4800 mAh, and a very significant increase in charging speed. It is understood that this graphene battery can fully charge Apple's 11-inch MacBook Air laptop in 13 to 15 minutes. Its charge and discharge life reaches 3,500 times, which is seven times that of traditional lithium-ion batteries. Graphene is a very magical material that has the ability to completely change the world. In addition to more efficient battery performance, this material can also be used to create flexible displays that can also be used to improve efficiency and fingerprint sensors. It should be mentioned that although this battery technology has a very good performance, it is not yet mature enough to be applied to electronic devices such as smart phones. We may have to wait for some time to see its practical application. According to the different production methods of Calcium Carbonate, calcium carbonate can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate. White solid, tasteless and odorless. There are two forms of amorphous and crystalline. The crystal type can be divided into orthorhombic crystal system and hexagonal crystal system, which are columnar or diamond-shaped.
