Poor battery life and the need to constantly recharge mobile devices like smartphones can often be a huge pain for consumers.
However, thanks to tin, lithium ion batteries which are commonly found in today’s mobile devices can last more than three times longer. As a result this has helped meet the huge demand for better batteries used to power up mobile phones, cameras, iPads and other multimedia devices.

So how is this possible?

Graphite, which has traditionally been used for the anode, one of the two main components in a battery cell, is more often than not being replaced by tin. The metal is able to hold more lithium ions than graphite, thereby increasing the energy storage capacity of a battery cell by nearly three times.

When you charge a battery, lithium ions travel from the cathode to the anode, where the anode holds onto the lithium ions to store the energy. When you use a battery, the lithium ions then move from the anode to the cathode and let loose electrons in the process.

It may sound complicated, but in reality, it means mobile devices can be charged faster and remain switched on for longer.

So next time you’re interacting on your mobile phone, take a moment to remember the role tin has played in ensuring your device is powered up for maximum enjoyment.
