The traditional liquid lithium battery is described by scientists as rocking chair batteries. The two ends of the rocking chair are the positive and negative poles of the battery, and the middle is the electrolyte (liquid). The lithium ions are like excellent athletes running back and forth between the positive and negative poles, and the battery is charged and discharged during the exercise.
However, this seemingly interesting structure has hidden dangers. Traditional lithium batteries may have lithium dendrites when operated at high currents, which can puncture the diaphragm and cause short-circuit damage. The electrolyte is an organic liquid, which will aggravate the tendency of side reactions, oxidative decomposition, gas generation, and combustion at high temperatures.

According to incomplete statistics, 10 combustion accidents occurred in electric vehicles in the first half of this year. The fire department concluded that the most common scenario in which new energy vehicles are burning during charging. In addition, the battery will burn during driving or stopping.
Weifang Dr. Sound Acoustic Technology Co., Ltd. has established the complete R&D verification system and a small-scale production line of graphene-modified lithium battery. In early 2017, we successfully produced graphene-modified lithium iron phosphate batteries, lithium cobalt oxide batteries, and ternary lithium batteries. All the performances of lithium batteries have been tested by authoritative organizations and proved to be a breakthrough. Our core competitiveness lies in high-quality graphene and lithium-ion battery technology. Our vision is to promote advanced lithium-ion battery materials and technologies without reservation, to improve the technical level of the entire industry, and to make the contribution of China's new energy industry leader in the world.
