Batteries That Last Forever

Most of us have become increasingly more dependent on our smartphones and other electronic equipments to run our daily lives. Because of this reality, we usually dread running out of battery. We try to find a way to always stay connected. In one word, having enough “juice” is something that has become truly important for many of us.

The reality is that the batteries that are powering our devices have become better in the last decades. Their capacity compared to their size have increased which has enabled manufacturers to develop better and more powerful devices. On the software side as well, many functions needed to operate specific applications have become lighter and consume less energy. The best practical example of the improvements in batterie technology might be Tesla. The company understood many years ago that specific types of batteries had become sufficiently good to create a car that would be 100% electric. Without these advancements in batteries technologies, Tesla couldn’t have done what it achieved commercially.

Still for most consumers, our smartphone or laptops batteries never seem to last long enough. And it’s true. Even the latest Apple product, the Apple Watch, cannot be used for more than a day without being charged. It’s a real pain and manufacturers are always trying to squeeze the additional hour of battery as a marketing argument for their products.

Fortunately, this might change in the coming years. The reason for this is that many startups and large companies are actively thinking about this issue and are investing massively in new technologies.

Several approaches are being considered. Some companies are trying to reduce the time it take to recharge your battery, providing consumers a way to charge 80% of their phone in a minute or so for example. Others are looking for new and completely different technologies to make batteries last for a much longer time, such as a week or so. Other companies are looking for a way to charge batteries wirelessly which then make device virtually constantly plugged in our wireless world. Others are looking to hydrogen or other type of energies.

We don’t know yet which will prevail over time but the winning solution is probably already there somewhere. Real advancements have been achieved and we should see soon enough the commercialization in the mass market of those advances. We can think that in a decade or so, charging your battery won’t be something you ever have to think about as a specific “quantum leap” would have been achieved.
