Huawei Introduces Graphene-Assisted Li-Ion Batteries

We’re using smartphones on a daily basis, pretty much everyone owns one these days, and we use them for various purposes. Now, considering how much we use our smartphones, it is very important that they’re able to not only perform well, but keep running at least until the end of the day. Well, unfortunately, that is not the case for quite a few smartphones out there, as some of us are able to kill their batteries before it’s time for bed, and that especially applies for those of you who use your smartphones a lot during the day. Every single part inside of a smartphone had evolved over time except for batteries, we’re still using regular batteries and the only thing that improved are their charging speeds, which helps a bit, but it’s not a solution.

Having that in mind, every single new battery technology that is pushed out to the market is a welcomed one, and Huawei just made a rather interesting battery-related announcement that is not exactly solving this problem, but is a step in the right direction at the very least. Watt Laboratory is an organization under Huawei’s Central Research Institute, and this organization has just announced graphene-assisted Li-ion batteries. These batteries can withstand higher temperatures than the regular Li-ion batteries we’re used to, they can withstand temperatures up to 60°C (140℉), while the regular Li-ion batteries we’re using these days can run at a maximum of 50°C (122℉). In addition to that, they have a really long lifespan, they can run twice as long as regular batteries, and can extend the range of EVs in high temperatures. Now, such batteries will be quite useful in smartphones, especially in really hot areas around the world, and they can also be utilized in drone, mainly considering drones produce quite a bit more heat than smartphones.

Watt Laboratory is using three technologies to make such batteries possible, first is a special additive in the electrolytes which removes trace water and prevents electrolytes from evaporating at higher temperatures. The second thing Chief Scientist at Watt Laboratory, Dr. Yangxing Li, mentioned, are modified large-crystal NMC materials. The company is using these materials for the cathode, and they’re able to improve thermal stability of the cathode powder. Now, some of you have probably guessed that graphene is also a part of the package, and that is correct, Watt Laboratory is using graphene as well, and it allows for more efficient cooling of these batteries. As a result of all this, Watt Laboratory’s batteries are cooler than regular Li-ion batteries while charging. After they’ve recharged this battery 2,000 times at a temperature of 60°C (140℉), it retained more than 70% of its capacity, which is quite impressive, and considerably better compared to regular Li-ion batteries. This technology will be available soon, and Huawei will introduce a smartphone sporting such a battery in late December, so stay tuned for that.
