Third of global food production at risk from climate crisis

Last modified on Fri 14 May 2021 12.50 EDT A third of global food production will be at risk by the end of the century if greenhouse gas emissions continue to rise at their current rate, new research suggests. Many of the world’s most important food-growing areas will see temperatures increase and rainfall patterns alter drastically if temperatures rise by about 3.7C, the forecast increase if emissions stay high. Researchers at Aalto University in Finland have calculated that about 95% of current crop production takes place in areas they define as “safe climatic space”, or conditions where temperature, rainfall and aridity fall within certain bounds.

Aalto researchers discover LiCoO2 electrodes can be recycled without crushing or melting

Aalto researchers discover LiCoO2 electrodes can be recycled without crushing or melting Researchers at Aalto University in Finland have discovered that Li-ion battery electrodes containing cobalt (LiCoO 2) can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy. The research is published in the journal ChemSusChem. In our earlier study of how lithium cobalt oxide batteries age, we noticed that one of the main causes of battery deterioration is the depletion of lithium in the electrode material. The structures can nevertheless remain relatively stable, so we wanted to see if they can be reused.

Researchers at Aalto University in Finland discovered that cobalt-containing electrodes in lithium batteries can be reused ‘as is’ after being newly saturated with lithium. Compared to conventional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials – and likely also energy. “In our earlier study of how lithium cobalt oxide batteries age, we noticed that one of the main causes of battery deterioration is the depletion of lithium in the electrode material.
