    Abstract: Recently, many different synthesis methods
    of olivine lithium iron phosphate (LiFePO4) are proposed to get a better performance for LiFePO4 batteries. The major flaws are low conductivity and low lithium diffusion constant. A major suggestion to solve the drawbacks is that the LiFePO4 material
    has to be in nanoparticulate form with intimate carbon contact. In previous studies,
    collision-coalescence growth mechanism has been used for flame synthesized iron oxide and carbon nanoparticles. The prediction of specific surface area (SSA) in a high temperature surrounding is formulated by Brownian collision-coalescense model. Moreover, the relationships among particle
    size, residence time, initial particle concentration and temperature will be discussed in detail. The prediction model of carbon-coated LiFePO4 can be applied to combustion flame chemical vapor deposition (CF-CVD) method in the future.
