Market-leading electrode binder material 

The Kynar® HSV series of PVDF binders offer easy processing, high throughput, stable slurry viscosity, and very high adhesion through many cycles and wide temperature fluctuations. Lower binder loading can be achieved while maintaining high adhesion through Arkema’s careful control of the functionalization of the binder resin. This allows for higher concentrations of active materials, lower internal resistance, and high cohesion across the electrode.

  • Kynar® HSV 1810 >> the functionalized PVDF designed for NMC batteries 

粘结力

Kynar® HSV 树脂在减少粘结剂用量的同时保持高粘结力,从而增加正极材料的含量,带来更高的能量密度。Kynar® HSV 树脂在常见溶剂及电解液中表现出极低的溶胀性(即使在高达80°C的高温条件下也保持极低的溶胀性)。

正极材料相容性

无论使用什么正极材料,粘结剂提供高粘结性是至关重要的。Kynar® HSV 树脂系列为以下正极材料带来优异的粘结性能:LCO, LFP, LMO, NMC 及 NCA。若有其他材料需求,请联系我们。

平衡的粘结力和柔韧性

在电解液环境下电池的长期性能至关重要。电池也会受到许多机械压力,因此在电池弯曲后粘结剂仍保持粘结力而不开裂对于未来的电池市场至关重要。与市场上的其他竞争材料相比,Kynar® HSV 1810具有出色的柔韧性。
