Huawei makes a huge breakthrough in graphene-assisted Li-ion batteries

Huawei made a significant breakthrough in graphene-assisted high temperature Li-ion batteries, according to an announcement made yesterday. The unveiling was made by Watt Laboratory, an organization under Huawei’s Central Research Institute, and allows batteries to run hotter as well as increase their lifespan.

Details after the break.

With this breakthrough, Li-ion batteries can run hotter than traditional Li-ion batteries at 60°C or 140℉. That’s an increase of 10°C or 18℉ in traditional batteries. Not only that, but in the announcement, Watt Laboratory noted that this means these new batteries can last up to two times longer than traditional Li-ion batteries.

From Huawei:

“Dr. Yangxing Li, Chief Scientist at Watt Laboratory, pointed out that three technologies contributed to the breakthrough in the graphene-assisted high-temperature Li-ion battery. First, a special additive in the electrolytes can remove trace water and prevent the electrolytes from evaporating in high temperatures. Second, modified large-crystal NMC materials are used for the cathode, improving the thermal stability of the cathode powder. Third, graphene allows for more efficient cooling of the Li-ion battery.”

While they did announce this breakthrough technology just yesterday, there’s been no info on if or when Huawei devices will sport the new battery technology. We’ll probably see more information on that early next year, probably around MWC 2017 in Barcelona.

Another big announcement from Huawei today: their quick charging technology announced way back in 2015 at the 56th Battery Symposium in Japan is finally getting a real-world application.

It’s able to charge 48% of a 3,000mAh battery in just five minutes. That’s insanely fast, but we have yet to see a device with it. But, now Huawei is saying that this quick charging technology will make its real-world debut with a Huawei smartphone set to be announced in late December.

If we’re going by that timeline — Huawei announcing this quick charging technology in 2015 — it could be another year before we see these new Li-ion batteries in devices.
