While processing power and camera quality have been improving at a fast pace in recent years, battery life and charging times have only made comparatively small steps forward and remain a major bottleneck in smartphone performance. We've seen several concepts and technologies, for example Storedot and its fast charging technology, addressing the issue being presented but thus far none of them has made it into mass production.

Now, Chinese manufacturer Huawei has presented some potential battery tech advancements: two prototype removable lithium-ion batteries that, with a custom charger, can be fully recharged in only a few minutes. In a demonstration video the smaller of the two batteries goes from zero to 68% charge in only two minutes, but unfortunately its capacity is not enough to power a mobile device for long. The second prototype, which according to Huawei provides approximately 10 hours of talk time on a smartphone, gained a 48% charge in five minutes.

Huawei does not provide a lot of detail about how the batteries work but says it is using heteroatoms - atoms that aren't carbon or hydrogen. According to the manufacturer, heteroatoms can accelerate charging speeds without having a negative impact on the battery's overall lifespan. You can watch the charging demonstration in two videos for the two-minute and five-minute experiment.
