The ever-growing demand for lithium-ion batteries (LIBs) and the shortage of metal minerals have led to urgent needs in battery recycling. Current recycling technologies cannot keep up with the exaltation of the LIB market and meet UN Sustainable Development Goals (SDGs). A holistic assessment of environmental tradeoffs is critical
Lithium‐ion batteries play a significant role in modern electronics and electric vehicles. However, current Li‐ion battery chemistries are unable to satisfy the increasingly heightened
In our lifetimes, we''ve gone from popping batteries into our remote-control toy cars to stepping into fully electric vehicles. This technological leap has been made possible in part by the evolution of traditional lithium ion to lithium metal batteries (LMBs), rechargeable batteries with about 10 times higher specific energy than their predecessors.
Our results show the potential to develop sustainable battery systems based on SIBs and PIBs and support battery developers in identifying hotspots for developing new-generation batteries with lower environmental impacts and supply risks.
For the first time, a team of researchers has studied the effects of tiny areas within lithium metal batteries that are much hotter than their surroundings. These hotspots, the researchers find, can make batteries grow spiky tumors of metal called dendrites that could cause short circuits, and potentially lead to fires.

Here we introduce a method to induce and sense localized high temperature inside a lithium battery using micro-Raman spectroscopy. We discover that temperature hotspots can induce significant lithium metal growth as compared to the surrounding lower temperature area due to the locally enhanced surface exchange current density.
Localized high temperature was created internally in a Li battery with a laser and measured using a micro-Raman spectroscopy platform. Li deposition rate was found to be orders of magnitude faster on the hotspot due to the enhanced surface exchange current density.
Hotspot-induced battery shorting. a Schematic of an optical cell with Cu and lithium cobalt oxide (LCO) as the electrodes. b Cell voltage as the battery was charged at a constant current of 30 μA. After onset of shorting, the voltage started to drop and fluctuate.
To understand how local hotspots affect the battery, Li growth behavior in the presence of a hotspot with controlled temperature was investigated on the Raman spectroscopy platform and examined by scanning electron microscopy (SEM).
The technical challenges and difficulties of the lithium-ion battery management are primarily in three aspects. Firstly, the electro-thermal behavior of lithium-ion batteries is complex, and the behavior of the system is highly non-linear, which makes it difficult to model the system.
As a critical quantitative metric for lithium-ion battery health diagnosis and secondary utilization, SOH can reflect the current performance attenuation level of the battery in a timely manner. The formula for SOH is mostly considered to be specified from the capacity of the battery.
