Poly(vinylidene fluoride)-grafted-Barium titanate (PVDF-g-BaTiO₃) nanocomposites were used as binders to prepare cathode material containing 70 wt% of active material (LiMn₂O₄), 18 wt% of conducting agent (carbon black) and 12 wt% of binder (either commercially available PVDF, modified PVDF such as PVDF-g-BaTiO₃, or both). A calendering process was used in order to obtain homogenous films and a better dispersity of nanoparticles. First, the electrochemical behavior of the modified PVDF was explored in the absence of the active material and did not revealed any electrochemical activity. Then, after adding the active material into the formulation (4–12 wt%), cells made with commercially available PVDF displayed similar cycling performances as the one achieved from 4 wt% of modified PVDF. For example, at 1C, the initial discharge capacities were 146, 140 and 130 mA h g⁻¹ for films made by 0, 4 and 8% of modified PVDF, respectively. Moreover, with the increase of charge discharge rate to 10C, the capacity can be approximately recovered when the current density returned to 1C for all the samples, revealing a good reversibility of the structure. On the other hand, calendering procedure enables to obtain a uniform structure demonstrated by reproducible tests as compared to those achieved from non-calendered films. Moreover, the calendering process showed an enhancement in cycling performances. For instance, the initial discharge capacity at 1C was 124 and 108 mA h g⁻¹ and decreased to 82 and 2 mA h g⁻¹ at 10C for non-calendered and calendered sample made with commercial PVDF, respectively.

以聚偏二氟乙烯-接枝的钛酸钡（PVDF- g -BaTiO ₃）为复合材料制备正极材料，该正极材料含70％（重量）的活性材料（LiMn ₂ O ₄），18％（重量）的导电剂（炭黑）。 ）和12 wt％的粘合剂（可商购获得的PVDF，改性的PVDF，例如PVDF- g -BaTiO ₃， 或两者）。为了获得均匀的膜和更好的纳米颗粒分散性，使用了压延工艺。首先，在不存在活性材料的情况下探索了改性的PVDF的电化学行为，并且没有揭示任何电化学活性。然后，将活性物质添加到配方中（4–12 wt％），用市售PVDF制成的电池显示出与4 wt％的改性PVDF相似的循环性能。例如，在1C下，初始放电容量为146、140和130 mA h g ^-1分别由0％，4％和8％的改性PVDF制成的薄膜。此外，随着电荷放电速率增加到10C，当所有样品的电流密度恢复到1C时，容量可以大致恢复，显示出良好的结构可逆性。另一方面，与从非压延膜获得的那些相比，压延过程能够获得通过可再现的测试证明的均匀结构。此外，压延过程显示出循环性能的增强。例如，对于用商业PVDF制成的未压延和压延样品，在¹ ℃的初始放电容量分别为124和108mA h g ^-1，在10℃降低至82和2mA h g ^-1。
