Energy storage has been holding back technological developments- from the simplest of portable gadgets to electric vehicles and renewable energy systems. Groundbreaking discoveries and improvements to the existing technology are long overdue, as numerous scientific and engineering teams have been working hard, for quite some time now, to bring that desired and greatly anticipated new generation battery technology. The right way to go is not yet entirely clear, as so far both those, who try to find better alternatives to lithium, and those, who try to improve on the current Li-ion technology, have shown equal success (or lack of it). But, the wait might finally be over. Huawei, a leading technology provider, turned quite a few heads around at the Battery Symposium in Japan, where the company revealed their revolutionary super-fast charging battery. The new fast charging energy storage technology has the same chemistry as any other conventional Li-ion battery, but the difference is in the graphite atoms bonded to the anode. The result- one battery of 600mAh capacity can be charged from 0 to 68% in two minutes. A battery with bigger capacity of 3000 mAh, and density larger than 620 Wh/L, which can provide ten hours of talk time on a regular Huawei smart phone, can reach just under 50% in five minutes. According to the makers, their fast charging technology does not compromise the energy storage capacity or battery life. Such innovation in the field of energy storage is needed now more than ever, as the demand for smart phone and electric vehicle technologies that are better, lighter, more efficient or more sleek, has never been so huge. StoreDot, an Israeli startup, recently revealed a similar technology, but since it was introduced last year, we have heard nothing about development or plans to hit the market. Similarly, Huawei has not yet committed to exact dates when customers can benefit from the new technology. Let’s hope this is not the last we hear from them.

The newly unveiled batteries reportedly charge ~10 times faster than conventional lithium-ion batteries do, and can recharge to 50% capacity in only a couple of minutes (for batteries of lower sizes). Huawei Green Car Congress provides more: Huawei presented videos of the two types of quick charging lithium-ion batteries: one battery with a 600 mAh capacity that can be charged to 68% capacity in two minutes; another with a 3000 mAh capacity and an energy density above 620 Wh/L, which can be charged to 48% capacity in five minutes to allow ten hours of phone call on Huawei mobile phones. To develop the fast-charing cells, Huawei engineers bonded heteroatoms to the graphite molecules in the anode. Introducing defects and heteroatom and/or functional groups into carbonaceous anode materials has been shown in other work to increase available active sites and effectively modulate the electronic and chemical character of the anode material. Huawei stated that the heteroatoms increase the charging speed of batteries without decreasing energy density or battery life. Of course that’s what they would say, though, isn’t it? We’ll have to wait until these are independently tested (or such independent test results are revealed) to comment further on this. If true, the results do sound quite nice, though, don’t they? I wonder if the improvements with regard to charging rates can scale up to the battery pack sizes used in EVs?
