Samsung develops new battery technology: double the capacity

According to news from foreign media engadget, Samsung has developed a new battery technology that can double the current battery capacity.

Battery is currently the weakest link in electronic products. Compared to the processor or the screen, the battery technology has not undergone any essential development for many years. One charge per day has become the norm.

Researchers at Samsung are using silicon nanoparticles coated on graphene, which allows silicon nanoparticles to have enough room for movement when needed. Graphene, on the other hand, has excellent electrochemical properties that make it 1.5 to 1.8 times more energy-efficient than regular cell phone batteries, which means the current cell phone may double in the same volume.

Silicon can accommodate more electricity than graphite anodes used in lithium batteries. This is not the first time people use silicon on batteries. The problem with silicon as an anode material was that it generated during charging and discharging Significant volume change, which will destroy the silicon anode, affecting battery performance.

At present, this is only a laboratory product, not commercialized, we should not see it on Samsung's next-generation mobile phones, but this means that the battery technology is a step forward, the future of mobile phones may be improved.
