A few days ago, engineers at the University of Maryland in the United States modified the wooden structure to make the negative electrode structure of the lithium battery to enhance the safety and performance of the battery
.
The study's paper, "Large-capacity, low-flexure, channel-guided lithium batteries," was published in the March 20 issue of the Proceedings of the National Academy of
Sciences.
Lithium batteries play an important role in modern manufacturing, whether it is a power bank, mobile phone, notebook or electric vehicle
.
However, this battery expands rapidly with the negative electrode when fully charged and shrinks
when the power is exhausted.
Obvious structural changes will lead to more lithium metal on the surface of the battery, which in the long run will bring safety hazards
such as explosion.
Scientists at the University of Maryland have proposed abandoning the traditional practice of using metal blocks to store lithium ions and instead using natural pipes in wood that transport water and nutrients to contain lithium ions
.
In this way, wood becomes a "home"
for metal ions.
Due to the fixed structure, the wood will not collapse or be damaged
, regardless of the change in the number of ions.
The researchers said that the current use of natural materials such as wood to improve the construction of lithium batteries is only part of the
research.
It is natural biological structures that inspire scientific research, allowing people to think of new ways
to store energy from renewable materials.
