The department of research and investigation of Huawei integrates several branches and one of their laboratories, more specifically the "Watt Laboratory" made an announcement particularly interesting at the time of their participation in an annual conference on batteries, an event that is going on in Japan at this time.

Graphene, the keyword
The great advance in battery technology due to the material Graphene, a carbon-based material and with the thickness of an atom. In turn, the carbon atoms that constitute this material are organised, especially in a provision similar to the honeycomb of a beehive. This peculiar arrangement makes the traffic a material extremely strong, about 100 times stronger than steel more resistant in the world, and with the excellent characteristics and properties of heat transmission and energy, as well as being an incredible heat shields.
This curious material is the key point of the new battery technology of Huawei. According to the “Watt Laboratory”, the new batteries of Huawei can withstand temperatures up to 60 ° C, over -10 ° C of the maximum limit of the batteries in all existing mobile devices today. According to its creators, the batteries that employ this graphene coating will double the life time of the equivalent current with the same capacity (mAh).
The head of this “Watt Laboratory”, dr. Yangxing Li said also some of the tests performed with this new technology for batteries, namely:
“We have carried out tests of charge and discharge of batteries in environments of high temperature. The tests reveal that, when the parameters are the same, the new batteries with isolation of graphene remain fresh, up to 5 ° C, than the batteries normal lithium-ion.”
in addition To staying cooler, this new technology from Huawei presents more advantages, namely: “The new batteries that use graphene are able to retain 70% charge after being recharged 2000 times at a temperature of 60 ° C, losing less load, discharging less than 13% when left for 200 days in a controlled environment at a temperature of 60 ° C”.
For its part, the batteries current lithium-ion degrade rapidly after two or three, are very used or not. The components of the battery degrade after this period, even if you have the device saved in a drawer, and the high temperatures accelerate the aging process. Now, if these numbers are correct, the Huawei may have discovered here something extremely valuable. Batteries are more resistant to high temperatures, with smaller and slower aging, up to 4 years up to that show clear signs of degradation.
finally, and to the great regret of ours, the new batteries of the Huawei are not yet ready to be used in the next devices Huawei but, it is without doubt a great step in the right direction!
