Chemical causes of battery ‘capacity fade’identified – Lithium Ion Battery / Manganese

Like you, me and everyone we know, batteries have a finite lifespan. When a battery enters “old age,” scientists refer to its diminished performance as “capacity fade,” in which the amount of charge a battery can supply decreases with repeated use. Capacity fade is the reason why a cell phone battery that used to last a whole day will, after a couple of years, last perhaps only a few hours. But what if scientists … Continue reading

THE SCRAMBLE FOR COBALT

The scale and speed of the Cobalt price surge over the last few months reflects a scramble for units. Lithium was the super-hot metals story of 2016. A spectacular price rally propelled lithium out of the metallic shadows onto the global investment stage. This year it is the turn of Cobalt. The price of cobalt traded on the London Metal Exchange (LME) has exploded from $33,000 per ton to $55,000 since the start of … Continue reading

New Graphene based electrode may solve Solar energy storage challenge

Scientists develop new graphene based electrode that could boost the capacity of existing solar integrable storage technologies by 3,000 percent. The prototype also opens a new path for the development of flexible thin film all-in-one solar capture and storage. (Source: RMIT University) Inspired by an American fern, scientists have developed a new graphene based electrode that could boost the capacity of existing solar integrable storage technologies by 3,000 per cent. The “groundbreaking” prototype created … Continue reading

BBC News: Graphene-based sieve turns seawater into drinking water

By Paul Rincon Science editor, BBC News website A UK-based team of researchers has created a graphene-based sieve capable of removing salt from seawater. The sought-after development could aid the millions of people without ready access to clean drinking water. The promising graphene oxide sieve could be highly efficient at filtering salts, and will now be tested against existing desalination membranes. It has previously been difficult to manufacture graphene-based barriers on an industrial scale. … Continue reading

Liquid metal battery inventor questions Lithium-ion as grid-scale storage solution

By: Terence Creamer Creamer Media Editor iquid metal battery inventor Professor Donald Sadoway, of the Massachusetts Institute of Technology, believes the technology has the potential to provide the “missing piece” in an electricity market that relies on “redundancy and overcapacity” to balance supply and demand – a feature that will become even more pronounced as the penetration of variable renewable-energy supply expands. Speaking at the Power & Electricity World Africa 2017 conference and exhibition … Continue reading
