News of revolutionary new battery technology often hits the headlines, but it is as well to look past the hyperbole to find out what is really going on. But not too much credit, because that was some time ago and, crucially, we still do not actually have glass batteries with massively more capacity than lithium-ion to power our cameras. Most practical batteries involve several cells, each of which is an individual package of chemical components required to accept and release electrical charge.
Yes, we would like to be able to run very big lights for long periods using batteriesThe purpose of the glass in the new design is to behave as an electrolyte - the lemon juice in our physics classroom experiment. John Goodenough, inventor of lithium-ion batteries - a highly respected Nobel….
