The Huawei announced new lithium batteries with graphene


The Huawei made important announcements today regarding the batteries. To be more accurate, announcements made by Watt Laboratory, an organization that belongs to the Central Research Institute of Huawei.

The announcements were made under the 57th Battery Symposium in Japan. There, the company announced the first Li-ion battery, assisted graphene. Graphene is a carbon material having a thickness of an individual, wherein the individual atoms are arranged in a honeycomb shape. This material is 100 times stronger than the strongest steel and has great potential in terms of heat and electricity. Therefore, graphene could be used as an ideal heat shield.

This is the function of the Huawei’s battery. The battery was announced today by Watt Laboratory can withstand up to 60 ° C. This means that exceeds by 10 ° C the current ceiling. According to its creators, Assisted Graphene Li-ion battery has a lifespan twice the normal Li-ion batteries with the same capacity.

The official announcement stated that there have been charge and discharge testing in environments with very high temperatures. The tests showed that when the working parameters being equal, at high temperatures the battery Graphene has a lower temperature by 5 ° C than a normal battery. Over 70% of the battery capacity with graphene remained after 2000 loads at 60 ° C. Less than 13% of the capacity was lost after remaining in an ambient temperature 60 ° C for 200 days.

In comparison, the majority of the Li-ion batteries lose very quickly their capacity after 2-3 years. This is either used or not. At high temperatures the loss is even more rapid.

If they are correct, the above figures, the Huawei’s battery should be withstand temperatures of 60 ° C for about four years. These batteries unfortunately not expected to get even the devices. But a new technology will debut in December and called super-quick charging Li-ion battery. It remains to be seen how quickly actually charging the battery.
