Scientists identify the cause of harmful dendrites and whiskers in lithium batteries

PNNL scientists Chongmin Wang, Wu Xu and Yang He use the specially modified transmission electron microscope to record images and videos of growing whiskers in a lithium battery. Picture credits: Andrea Starr / PNNL Scientists have discovered a cause for the growth of needle-like structures known as dendrites and whiskers that plague lithium batteries, sometimes causing a short circuit, failure, …

A new coating could be the key to lighter lithium metal batteries

The problem with lithium-metal batteries is that they often develop small, tendril-like protrusions called dendrites. Over time, dendrites can pierce the protective film separating the positive and negative ends of the battery. And if the two sides interact with each other, there is a risk of a short circuit, which in turn can cause the entire energy cell to catch …

Tesla warns of impending shortage of battery minerals like nickel, copper and lithium

Tesla fears that a global shortage of minerals will soon emerge for the production of batteries for electric cars such as nickel, copper and lithium. The electrical revolution in the automotive industry is increasing the demand for batteries at an incredible pace, which in turn increases the demand for certain minerals used in the production of Li-Ion battery cells. It's …

A new battery could store ten times as much energy as lithium ions

Batteries not included The batteries are great. They supply many of the brands of the future, from smartphones to electric cars. The problem is, of course, that batteries never seem to last long enough with one charge – and their environmental impact is significant. Now, however, an all-star team of researchers from Caltech, NASA's Jet Propulsion Laboratory and NASA Honda …

Batteries: Lithium Ion or Solid State? – Autoevolution

The batteries that the automotive industry needed were lithium-ion batteries. The invention is largely attributed to either the German-born scientist John Bannister Goodenough. The concept was born in 1980 as a lithium-cobalt-oxide cathode battery, but only in 1991 was it commercially used by Japanese companies. With neither Goodenough nor the Oxford University chemistry lab he was working on applying for …
