Huawei has said about the next opening in the field of batteries. The company says it has created the world’s first lithium-ion battery with the use of graphene, which is released a long service life and ability to operate at elevated temperatures.
This is the event Battery Symposium in Japan, told representatives of the laboratory Watt Laboratory, which is part of Huawei. Judging by the wording and the lack of photos of the product at the show was not shown.
The battery is released twice as long service life and the ability to endure higher temperatures when compared to conventional lithium-ion batteries. In particular, the upper temperature limit is 60 ° C.
The press release says that the battery is able to create thanks to the introduction of several technologies. For example, a special additive in the electrolyte helps to remove water from it, which prevents the evaporation of excess electrolyte at high temperatures. Also, the same graphene promotes more effective in reducing temperature of the battery. In particular, all other parameters remain unchanged developed battery temperature is 5 ° C lower than the average. Regarding durability, the capacity of the battery is maintained at about 70% of the original charge after 2000 cycles at a temperature of 60 ° C. When the battery is stored for 200 days at the same temperature, it loses less than 13% of the charge.
Development, apparently, is not aimed at mobile devices. So, Huawei says the use of battery storage systems, base station data in the hot areas, or even in the car segment. On the timing of commercial introduction of a new technology it does not say anything.
