In this work, we report a short and efficient carbothermic reduction process for the rapidly extraction of Li and Co from spent LiCoO 2 batteries. The pyrolysis gases of the PV panels were used to reduce LiCoO 2 to water-soluble Li 2 CO 3 and water-insoluble CoO/Co, with the aim to separate Li and Co that can be recovered separately. More importantly, the roasting
The results indicated that under optimal nitrification conditions—specifically, a temperature of 70 ℃, a reaction time of 5 h, and an acid-to-battery waste ratio of 30 mmol/g—coupled with roasting conditions of 250 ℃ for 1 h, the subsequent leaching process could achieve a lithium extraction rate exceeding 93 %, which showed that the process is also highly feasibility [69].
A new method for the sustainable utilization of waste lithium-ion battery separators was developed, involving the hydrochloric acid washing to partially remove the Al 2 O 3 coating, followed by catalytic pyrolysis to produce aromatic hydrocarbons with HZSM-5.

Biomass pyrolysis is an endothermic process occurring at relatively high temperatures (i.e. 700–900 °C) for producing syngas, tar and char (Kan et al., 2016).Meanwhile, the chemical pathways of biomass gasification are complex with a variety of reactions mainly including biomass pyrolysis, partial oxidation, gas and tar reforming reactions (Alauddin et al.,
Recycling of spent lithium-ion batteries has attracted worldwide attention to ensure sustainability of electric vehicle industry. Pretreatment as an essential step for recycling of spent LIBs is critical to ensure the recovery efficiency and quality of black mass which is used for further materials regeneration. Usually, high temperature pyrolysis, at around 600 °C is required during the
In recent years, the exponential growth of the electric vehicle market, 1 driven primarily by lithium-ion batteries (LIBs), has raised substantial concerns about the upcoming surge in end-of-life LIBs projected over the next 5–10 years. With global LIBs production now surpassing an impressive 1,400 GWh annually, 2 the urgency of securing lithium-ion battery-related
The rapid development of the new energy generation will lead to a large number of spent lithium batteries in the near future, and China''s recycled spent battery capacity is expected to reach 137.4 GWh by 2025 [5]. By 2030, the forecast number of EVs on the road will reach 253 million under the EV30@30 Scenario, as illustrated in Fig. 3 (d).
Traditional pyrometallurgy, which has been widely adopted in many countries, always transforms the waste battery strips into metal alloys at high temperatures 3,8–10. However, the high energy consumption hinders economic interests, and the inevitable loss of lithium during pyrolysis process remains a technical hurdle as well.
Catalytic pyrolysis (in-situ) and catalytic upgrading (ex-situ) are considered as the most promising methods for upgrading the biomass pyrolysis vapor (Shen and Fu, 2018, Shen et al., 2015b, Shen et al., 2015c).Catalytic pyrolysis has attracted much attention since it can increase both the carbon conversion and the reaction rate (Lu et al., 2020).
With the rapid development of the lithium-ion battery (LIB) industry, the inevitable generation of fluorine-containing solid waste (FCSW) during LIB production and recycling processes has drawn significant attention

To prevent battery short-circuiting from residual electri-city, waste batteries need to be discharged to less than 2 V. Common methods include sodium chloride solution, metal powder, and low-temperature discharge [39]. The sodium chloride solution method is widely used because of its sim-plicity of operation. After waste batteries are fully dis-

In the spent LiCoO2 batteries, the lithium recovery efficiency reaches 99.99% and purity reaches 98.3% at 500 °C. In addition, biomass pyrolysis gas reduction is also applicable to treat spent LiMn2O4 and LiNi0.6Co0.2Mn0.2O2 batteries. Thermodynamic analysis verifies that CO dominates the gas reduction recovery process.
The pyrometallurgical routes to recycle spent LIBs consist of two major approaches: (1) regeneration of electrode materials by lithiation or crystal repairs through a heat-treatment process, and (2) convert spent batteries into Fe-, Co-, Ni-, and Mn-based liquid alloys at a temperature higher than 1000 °C .
