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

熔融合成LiFePO4和LiFe(1-x)MnxPO4已经在中试规模上被证明是典型制造方法的低成本替代方案。由于LiFePO4在还原气氛下的快速反应动力学和热力学稳定性，使LiFePO4的高温过程在还原气氛中得以实现。该项目的目标是优化熔融合成工艺和合成后步骤，以生产C-LMP(M=Fe，Mn…)产品从实验室到中试，同时优化工艺路线，并推导出比例规则，以便根据汽车和大型蓄电池行业的原始设备制造商(OEM)的电化学性能和物理化学特性对材料进行合格鉴定。项目步骤为：1.从当地供应商(矿业公司和前体公司)选择反应物：不同品级和纯度的C-LMP合成及其评价2.中试规模合成和中试粉末加工：合成、粒度降低和热解步骤的优化。小电池的实验室检测和材料的鉴定和质量控制。OEM客户的现场测试
