Nagoya, Japan – Huawei Technologies Co. Ltd. demonstrated on Friday two state-of-the-art battery prototypes at the 56th Battery Symposium in Japan. These ultra-fast-charging batteries reach a speed 10 times faster than that of those available on the market, which means they can achieve nearly 50% its capacity in a few minutes.

Watt Lab, which belongs to the Central Research Institute at Huawei, presented videos of the two new types of fast-charging lithium-ion batteries. The one with a 600 mAh capacity can be charged to 68% in just two minutes, whereas the other with a 3000 mAh capacity can be charged to 48% in five minutes. With the last one, Huawei users can phone call for up to 10 hours on their mobile phones. These batteries have been extensively tested and then certified by the Huawei’s terminal test department. However, it remains unclear when they will be available on the market.

The company explained they achieved these results by bonding heteroatoms to the molecule of graphite in anode, “which could be a catalyst for the capture and transmission of lithium through carbon bonds.”

Huawei affirmed that heteroatoms allow increasingly fast-charging speed without reducing energy density or battery life. iPhone users, for instance, complain that their phones’ battery capacity decrease the more they use them.

Huawei’s claims this fast-charging technology could apply beyond the mobile phone’s field, including electric vehicles, wearable devices and mobile power supplies. The firm says people around the world will soon charge their batteries to 100% its capacity in the time it takes to grab a cup of coffee.

Nevertheless, Huawei is not the only company working on this technology. In March, Samsung claimed its Galaxy S6 batteries allow up to four hours of use after only ten minutes of charging, but Droid-Life tested and showed that in five minutes it only increases from 5% to 14%.

On the other hand, FlashBattery states their smartphone batteries can full charge in just one minute. The battery is made of synthesized organic compounds that help reduce charging time and boosts power capability. To date, no major smartphone manufacturer has adopted this technology, which was created by StoreDot.

In September, Qualcomm promised to charge smartphone batteries to 80% in 35 minutes with its quick charging technology called Quick Charge 3. The San Diego-based firm announced the new feature would be available on phones with the Snapdragon 820 processor.
