Your battery link is important news and actually well worth a 'C&P', skinny, IMHO:
A step towards new "beyond lithium" rechargeable batteries with superior performance has been made by researchers at the University of Bath.
We increasingly rely on rechargeable batteries for a host of essential uses; from mobile phones and electric cars to electrical grid storage. At present this demand is taken up by lithium-ion batteries. As we continue to transition from fossil fuels to low emission energy sources, new battery technologies will be needed for new applications and more efficient energy storage.
One approach to develop batteries that store more energy is to use "multivalent" metals instead of lithium. In lithium-ion batteries, charging and discharging transfers lithium ions inside the battery. For every lithium ion transferred, one electron is also transferred, producing electric current. In multivalent batteries, lithium would be replaced by a different metal that transfers more than one electron per ion. For batteries of equal size, this would give multivalent batteries better energy storage capacity and performance.
The team showed that titanium dioxide can be modified to allow it to be used as an electrode in multivalent batteries, providing a valuable proof of concept in their development.
The scientists, an international team from the University of Bath, France, Germany, Holland, and the USA, deliberately introduced defects in titanium dioxide to form high concentrations of microscopic holes, and showed these can be reversibly occupied by magnesium and aluminium; which carry more than one electron per ion.
The team also describes a new chemical strategy for designing materials that can be used in future multivalent batteries.
The research is published in the journal Nature Materials.

Depends on "his" definition of the future.

Just bought a brand new Samsung phone which is on the EE network and the sim card was registered on the phone this morning,but what i am trying to do is put a O2 sim card into the phone,the new O2 sim card arrived this morning as i needed a new micro sim card for the Samsung.
We are looking at keeping the same phone no that is on the O2 account and transfer it onto the new phone,so do i have to ask EE dor a pack no i think its called or o2 for this information so that i can transfer the No over.
Any help would be most welcome,i done it a few years back transferring a 3 account onto a Tesco phone,but forgot how i done it.

Trouble with the latest iCan is, there are lots of cheap packages but there are always strings attached!😊

Problem with swapping sims over has been resolved,would like too thank 'Hilary' who was a tremendous help and could not have done it other wise pmsl finally have my iCan up and running.

Yet a another reference to the "Cashless society"?... thanks but no thanks.
