The biggest shortcoming of current smartphones is the battery. There is no big breakthrough in technology and the safety is very low. Looking at the Note7 that sadly left the market this year, we know how miserable it is. Many manufacturers and scientists are working hard on batteries, hoping to find a point that will really detonate the commercial market. Judging from the current situation, graphene has the most potential. Now, the Watt Laboratory of Huawei Central Research Institute has announced that they have achieved a major research breakthrough in the field of lithium-ion batteries and launched the industry's first high-temperature and long-life graphene-based lithium-ion battery. This new high-temperature resistant technology can reduce the upper limit of the use temperature of lithium-ion batteries. Increased by 10°C, the service life is twice that of ordinary lithium-ion batteries. Regarding this major breakthrough, Dr. Li Yangxing, chief scientist of Huawei's Watt Laboratory, revealed that the breakthrough mainly comes from three aspects: adding special additives to the electrolyte to remove traces of water and avoid high-temperature decomposition of the electrolyte; selecting modified large-scale single-purpose batteries for the battery cathode Crystalline ternary material improves the thermal stability of the material; at the same time, the new material graphene is used to achieve efficient heat dissipation between the lithium-ion battery and the environment. Do you still remember the super charging technology that Huawei showed off last year? It can charge a 3000mAh battery to 48% in 5 minutes. Now Dr. Li Yangxing revealed that Huawei’s fast charging batteries are already commercially available and will officially release super fast charging mobile phones at the end of December this year. .
