Battery tech that stores over 9 times more energy is here and it’s perfect for your gadgets

Researchers at the University of Surrey created a Vertically Integrated Silicon-Carbon Nanotube anode for lithium-ion batteries.

The new anode stores about 3,500 mAh per gram versus roughly 370 mAh per gram for graphite anodes.

The design uses a flexible carbon nanotube scaffold coated with silicon to allow expansion without cracking and maintain cycle stability.

If the lab results hold in real devices, the technology could enable much longer-lasting phones and wearables without sacrificing reliability.
