Scientists have put forward a solution to a major problem plaguing lithium metal batteries, demonstrating how a finely tuned carbon membrane can prevent these types of battery form failure and enable them to be safely charged over hundreds of cycles.

A substance known as calcium phosphate cement is commonly used to repair broken bones, both holding them together and encouraging the growth of new bone tissue. Now, scientists have added carbon fibers to the material to also make it self-healing.

A breakthrough from an international team of researchers raises hopes of a new, targeted approach to regenerative medicine, demonstrating how violet light can be used to switch on a drug and promote growth in highly selective areas.
