Melt-synthesis of LiFePO4 and LiFe(1-x)MnxPO4 has already been demonstrated in pilot-scale as a low-cost alternative to typical manufacturing pathways. The high temperautre process in the liquid phase, benefits from rapid reaction kinetics and the thermodynamic stability of LiFePO4 in a reducing atmosphere. The objective of the project is to optimize the melt-synthesis process and the post-synthesis steps to manufacture C-LMP (M=Fe, Mn...) products from the lab- to pilot-scale while optimizing process path and deriving scaling rules in order to reach qualification of the material on the basis of electrochemical performance and physico-chemical characteristics by Original Equipment Manufacturer (OEM) of the automotive and large accumulator sectors. The project steps are:1. Reactant selection from local suppliers (mining and precursors companies): various grade and purities and thier evaluation for the synthesis of C-LMP tested 2. Pilot scale synthesis and Pilot-scale powder processing: optimization of the synthesis, particle size reduction and pyrolysis steps3. Laboratory testing in small cells and material qualification and quality control4. Field testing by OEM customers

LiFePO4 和 LiFe(1-x)MnxPO4 的熔融合成已在中试规模中得到证明，可以作为典型制造途径的低成本替代方案。液相高温过程得益于 LiFePO4 在还原气氛中的快速反应动力学和热力学稳定性。该项目的目标是优化熔体合成工艺和合成后步骤，以从实验室规模到中试规模生产 C-LMP（M=Fe、Mn...）产品，同时优化工艺路径并获得规模化规则，以便汽车和大型蓄电池行业的原始设备制造商 (OEM) 根据电化学性能和物理化学特性对材料进行鉴定。项目步骤是： 1．来自当地供应商（采矿和前体公司）的反应物选择：各种等级和纯度以及对测试的 C-LMP 合成的评估 2. 中试规模合成和中试规模粉末加工：优化合成、粒径减小和热解步骤3 。小电池实验室测试以及材料鉴定和质量控制4。 OEM客户现场测试
