A smartphone’s battery is designed to only work effectively between one and one and a half years, according to Business Insider. Yet, battery life is among the top features that buyers consider before buying a new phone. Regardless of how advanced your phone is, it becomes quite frustrating if you have to keep charging it up.

Lithium-ion(Li-ion) has been the industry-standard energy technology for a long time. With the emergence of phones with bigger screens, faster processors, and the slim feature, Li-ion batteries are struggling to meet the current power demand. After almost a quarter of a century of stagnation in the battery industry, we are set to witness a power revolution. Below are some game-changing mobile phone battery technologies.

Silicon Anode Batteries

Batteries power the world we live in, as experts at rightfully claim. The Lithium-ion battery which we use today comprises of cathodes, graphite anodes, and electrolyte. The graphite anodes are used to absorb lithium thus helping the battery to have better energy storage and preventing it from overheating. Still, graphite has limitations as it isn’t able to absorb lithium well enough.

Silicon has ten times more the capacity to absorb lithium. It can store higher amounts of energy, has a longer battery life, and charges faster. This makes it a better choice compared to graphite. After perfection, silicon anodes are projected to replace granite in Li-ion batteries.

Energy-Harvesting Nanogenerators

Soon, smartphone users may start using their bodies as a power source for their devices. Scientists have made some impressive steps forward and are working on a technology that will harvest energy from our bodies. Triboelectric nanogenerators (TENGs) collect biomechanical power when our bodies make movements.

The TENGs are incorporated into human clothing or footwear, and they gather and store any energy you create. This is a renewable and affordable source of power. All you have to do is move, twist, turn, and stretch, and you have enough power to keep your phone running.

Converting Wi-Fi Signals to Electricity

According to a survey report in the U.S. Today, 77% of Android users said longer battery life gets them excited about buying a new phone. Now, you don’t have to worry so much about your phone going off when you need it the most. Your smartphone doesn’t have to be plugged into a power source to recharge its battery.

Researchers have devised a way to harness AC power from Wi-Fi in the air and convert it to DC power. This power can be used to charge your smartphone or power it directly. With this technology, any location that has a Wi-Fi connection will be a charging station.

Foam Battery

Prieto Battery, a startup company has managed to build the first ever 3D battery. Made from copper foam, this battery comprises of 98% air. It can be charged quickly, store up power, and be discharged. The battery itself is as thin as a sheet of paper, it has a low environmental impact, and its production cost is cheap.

Foldable Battery

New phones are about to start being powered by a flexible battery. These batteries are paper-based and have the potential to store up to 14 times the energy stored by a conventional battery. It is folded up to 25 times using the Miura technique enabling it to occupy very little space without affecting its performance.


The current groundbreaking technologies in the phone batteries industry are good news to smartphone users. The combined efforts being made in this field will gift us with batteries that charge faster, last days without a recharge, function safely, and don’t gradually fail.
