Huawei has developed a lithium-ion battery with the introduction of graphene, which allows him to better Express themselves at high temperatures
Huawei announced yet another discovery in the field of batteries. The company says it created the world’s first lithium-ion battery using graphene, which is released a long service life and ability to operate at elevated temperatures.
This was at the event Battery Symposium in Japan, told representatives of the laboratory Watt Laboratory, which is part of the Huawei. Judging by the wording and lack of pictures, the product at the exhibition are not shown.
The battery is twice longer service life and ability to tolerate higher temperatures when compared to conventional lithium-ion batteries. In particular, the upper temperature limit is 60°C.
In the press release it says that to create the battery failed due to the introduction of several technologies. For example, a special additive in the electrolyte helps to remove water from it, which prevents unnecessary evaporation of the electrolyte at high temperatures. Also the same graphene contributes to a more effective reduction of the temperature of the battery. In particular, other constant parameters of the designed temperature of the battery 5°C lower than conventional. With regard to durability, the capacity of such accumulator is maintained at about 70% from the initial after 2,000 charge cycles at a temperature of 60°C. If the battery is stored for 200 days at the same temperature, it loses less than 13% charge.
Development, apparently, is not aimed at mobile devices. So, Huawei notes that the use of batteries for storage of base stations in hot areas or even in the automotive segment. On the timing of commercial introduction of new technologies does not say anything.
