Samsung Develops New Technology Could Double Smartphone Battery Life

As our smart-devices become able to doing extra, it usually implies that battery life takes a back seat, especially as smart units keep shrinking. Samsung researchers have developed a new method of developing lithium-ion batteries that tackles the problem of extending battery life on a nanoscale. The use of silicon in lithium-ion batteries is a widely researched growth, however a caveat to using silicon as an active material in Li-On batteries is that its volume drastically changes through charge-discharge cycles. This may lead to weakening the battery’s life cycle energy density.

Their design makes use of a silicon anode for enhanced electrical capacity; additionally, they added thin layers of graphene on the battery’s surface. The researchers found they may optimize the silicon anode’s performance by anchoring graphene on top of silicon nanoparticles. Now, as the silicon expands it may slide between the adjacent layers of graphene particles, preserving the silicon’s durability.

Graphene’s 2 dimensional carbon structure lends itself a wide array of scientific discoveries and has attracted $1.35 billion in research funding from the Graphene Flagship Consortium.

In testing, Samsung researchers found their method created power densities 1.5 to 1.8 times larger than traditional Li-On batteries. In theory, which means a device with a 13-hour battery life may go a full 24 hours with out a charge, due to these new batteries. It is still within the research phase, so extend our utilization time with external portable batteries within the meantime.
