Although most companies can introduce how advanced their equipment is, few people can demonstrate their battery technology. As the capabilities of our smartphones have become more and more powerful, but in the absence of battery technology innovation, this means the consumption of battery power. Fortunately, scientists at the University of California, Riverside, have found a way to not only improve battery performance by about three times, and this method is environmentally friendly, and all this is due to sand.
"This is a low-cost, non-toxic, environmentally friendly way to produce anodes for high-performance lithium-ion batteries," said researcher Phevos. For some time, Phevos and other scientists have focused their attention on nano-silicon. Unfortunately, the problems of rapid degradation and difficulty in mass production have almost brought things to a standstill.
Phevos studied possible alternatives to the graphite anode material and eventually found that high quartz proportions of sand worked well. He purified powdered sand and heated it to remove oxygen, producing pure silicon. The resulting material has a stronger energy density than graphite as an anode, which means that the duration of the battery is more than 3 times. In addition, the improved performance of the sand-based anode or more to increase the life of the battery is more than three times.
The results of this study are published in the "Natural Science", the pure silicon will sooner or later enter the consumer battery. Now the scientific research team is trying to mass produce nano-silicon, and plans to develop from the size of the battery to the battery used in the cell phone.
