This review investigates various synthesis methods for LiFePO 4 (LFP) as a cathode material for lithium-ion batteries, highlighting its advantages over Co and Ni due to lower toxicity and cost.
LiFePO 4 has a theoretical specific capacity of 170 mAh g −1, and a voltage relative to metallic lithium of 3.4 V for the Fe 2+ /Fe 3+ redox couple, resulting in a remarkably stable charge–discharge performance. LiFePO 4 batteries take olivine-structured LiFePO 4 as the cathode materials.
The recycling of these batteries has become a social problem and raises great attentions. Cathode materials are the most valuable components and their recycling is the most interesting to researchers. Hence, the general information of LiFePO 4 batteries and the failure mechanism have been introduced briefly.
The process maintains the olivine crystal structure of the raw material, as shown in Figure 7c, and the resulting Li 2 CO 3 product is of high purity (>99 %). In addition to sodium persulfate, another used and effective oxidant for handling spent LiFePO 4 batteries is H 2 O 2.
The discovered LiFePO 4 cathode with good cycling stability, low price and excellent safety is one of the most attractive cathode materials for LIBs. However, several crucial challenges including poor ionic and electronic conductivity and low Li + diffusion impede its high-rate application.
Destenay discovered LiFePO 4 (LFP) in triphylite mineral solid solutions, forming olivine and isomorphous structure with Li phosphates of divalent Mn and Fe. Remarkably, Prof Goodenough and his colleagues' ground-breaking work demonstrated the possibility of extracting Li from LFP using an insertion method for the first time .

Some of the common challenges to opportunities of hydrogen storage are highlighted below. 1. Low Energy Density by Volume: Hydrogen has a low energy density per unit volume, leading to the need for efficient storage technologies to store an economically viable amount of energy.
The challenges in realising the large-scale application of the hydrogen energy industry are mainly low-cost and high-efficiency fuel cell technology and safe and efficient hydrogen storage and transportation technology.
Conducting a comprehensive life cycle analysis of hydrogen storage technologies is crucial to assess their environmental impact from production to end-of-life. This includes evaluating resource use, emissions, and energy consumption at every stage. Assessing the sustainability of materials used in hydrogen storage technologies is important.
The environmental benefits of hydrogen storage technologies heavily depend on the method of hydrogen production. Green hydrogen, produced using renewable energy sources like wind or solar power through electrolysis, is considered environmentally friendly as it avoids carbon emissions associated with traditional production methods.
