Can electrode materials be recycled?
A lot of attentions have been paid to the exploration of the advanced technologies to recycle of spent LIBs because of resource conservation and environment protection. Proper disposal of spent LIBs can promote the development of renewable and sustainable energy. This research work focuses on the key point of the liberation of electrode materials.
How to liberate a cathode electrode?
The electrode scraps were thermally treated together with molten salt in a nitrogen atmosphere. The liberation efficiency of electrode materials was up to 99.8% at the optimal conditions: a temperature of 160 °C, molten salt: cathode electrode mass ratio of 10:1, and holding time of 20 min (Wang et al., 2019).
How are electrode materials liberated in the recycling process?
Based on the analysis of current references, the summary of chemical technologies for the liberation of electrode materials in the recycling process of spent LIBs is given in Table 1. In these studies, spent LIBs are firstly discharged and then manually dismantled to cathode, anode, membrane separator, and other plastics.
Can lithium electrodes be reused?
The new method sidesteps this painstaking process: by replenishing the spent lithium in the electrode through an electrolysis process, commonly used in industry, the cobalt compound can be directly reused. The results show that the performance of electrodes newly saturated with lithium is almost as good as that of those made of new material.
How to recover electrolytes after discharging batteries?
It is advisable to recover the electrolytes before the batteries go for shredding and sieving to get a higher recovery. One of the well-known approaches in recycling electrolytes is treating them with a supercritical (SC) CO 2 86 solvent mixture after discharging batteries.
