Technical advances are reducing the volume of e-waste generated in the US as lighter, more compact products enter the market. But those goods can be harder to reuse and recycle.

Batteries power much of modern life, from electric and hybrid cars to computers, medical devices and cellphones. But unless they’re made easier and cheaper to recycle, a battery waste crisis looms.
Electric vehicles can have a positive impact on the climate and air pollution levels, but governments should rethink how they electrify the transportation network.
M. Stanley Whittingham was one of three scientists who won the 2019 Nobel Prize in Chemistry for their work developing lithium-ion batteries – used to power mobile phones, laptops and electric cars.
Nobel Prizes in science are usually given for revolutionary ideas that change our perception of the universe. But this year’s chemistry prize was awarded to inventors of a revolutionary device.
Stanley Whittingham, John Goodenough and Akira Yoshino created a safe, light, rechargeable battery that has revolutionised society and is probably powering the device you’re reading this on right now.
A year ago, the world’s largest lithium-ion battery began dispatching power to South Australia’s grid. It has been a remarkable success but there are some concerns that have so far escaped scrutiny
Is it too much to dream of batteries that are part of the structure of an item, helping to shape the form of a smartphone, car or building while also powering its functions?
A new rechargeable ‘proton battery’ - made chiefly from carbon and water - promises to outperform conventional lithium-ion batteries, while also being more environmentally friendly.
Demand for energy storage is increasing – both in Australia and around the world. But issues with the production of lithium-ion batteries mean the search is on for alternatives.
