Seaweed ‘could be surprise catch in extending battery lives’

A food additive extracted from seaweed could prove to be a surprise key ingredient to power advances in technology that could extend the lifetime of lithium-sulfur batteries, according to researchers in the US.

Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory say they have discovered that carrageenan, a derivative of seaweed, acts as a stabiliser in lithium-sulfur batteries – and improved stability could lead to more cycling and extended lifetime.

Lithium-sulfur on brink of deployment thanks to OXIS Energy

Tue, 02/14/2017 - 11:20 -- Xuan Zhong

The world’s first commercially viable lithium-sulfur battery is on the brink of deployment after a deal between UK firm OXIS Energy and aerospace company Airbus Defence and Space.

OXIS Energy aims to increase its system’s  energy density to 425Wh/kg, which would allow a High Altitude Long Pseudo Satellite (HAPS) to fly in the troposphere for three months without needing to land.
