New Hitachi Maxell Li-Ion battery packs 60% more capacity in the same size
The biggest problem with smartphones today is battery life. It’s been so for many years now, but things are gradually getting worse, because manufacturers keep adding more and more battery-sucking things to our devices. Quad-core processors, Full HD touchscreens, many different connectivity options (4G, 3G, Wi-Fi, and so on) – all of these need power. The one thing that most companies have done to mitigate the effects of these new power guzzlers has been to fit increasingly large batteries onto our handsets. This has been made easier by the gradual transition to bigger and bigger screens on our mobile devices, but it’s definitely not a long term solution.
Every month, if not every week, it seems we find out about yet another battery discovery that’s said to revolutionize the mobile world, but none of those has ever made it into shipping products. That may be different for Hitachi Maxell’s latest Li-Ion battery.
It has an energy density 1.6 times larger than that of the company’s existing product. What this means is that it can fit 60% more capacity onto the same size. So, for example, for the exact size of a 2,000 mAh battery, you’d get 3,200 mAh of capacity. That’s really amazing, given how we love our phones to be thin.
But wait, there’s more! Hitachi Maxell’s new battery is also going to have a longer life than others before it. All of these advancements come because Hitachi Maxell managed to develop technology to monitor the movements of Lithium ions inside the battery in real time.
The company has used the findings it got from this monitoring to ensure that the distribution of reaction in its new battery is homogenized and the flow of Lithium ions doesn’t become stagnant. Essentially, what Hitachi Maxell has done is develop a battery structure that can resolve the stagnation of Lithium ions. This makes the deterioration rate of the battery slower (hence the longer lifetime), and it also makes it possible to pack all that extra capacity in.
Needless to say, we hope this makes it into shipping devices as soon as possible. All high-end smartphones in this day and age need at least a 3,000 mAh battery in order to be even decent performers for one day, and this new technology enables that to happen without any space constraints. What more could we want?
