The company said that the battery uses the same lithium ion chemistry used in mobilephone batteries today but gets its advantage from atoms of graphite bonded to the anode.
This means faster charging but not at the expense of usage life or a sacrifice in the amount of energy that can be stored in each battery, it claimed.
One of the two batteries has a capacity of 3,000mAh (milliampere hours) and can be charged to 48 percent of capacity in five minutes. The second has a much smaller capacity of 600mAh but reaches 68 percent of capacity in just two minutes.
Huawei didn’t say when the fast charging might make its way into commercial products.
The announcement is one of a number this year that all point toward faster charging or longer battery life. Advances in battery technology have lagged other areas of technology and battery life remains a limiting factor for gadgets such as phones and larger products like electric vehicles.
Hardly a week goes by without some improvement to batteries which curiously never make it to market. Last week researchers at Vanderbilt University said they had used quantum dots of iron pyrite, also know as fool’s gold, to realize a fast-charging lithium ion battery.
