The first is tapped density, which impacts the energy density of a Li-ion battery (LIB). The other is the particle size distribution. This property provides the necessary information for optimizing the grinding parameters during production. High-energy-density during LIB manufacture can also be improved by improving the tapped density.
Most importantly, the volume of lithium-ion batteries is limited. If the tap density is high, the mass of active material per unit volume is large, which is conducive to enhancing volumetric capacity and energy density.
The tap density of as-prepared material has a decreasing trend with the increase of the ratio of 9 μm sized particle in the materials. The highest tap density among all of the kinds of materials reaches up to 2.66 g cm −3.
The tap density has a significant impact on the volumetric energy density of LIBs anode materials. High tap density can improve the volumetric energy density of electrode materials, achieving densification of Sn based anode materials, thickening of electrodes, and thinning of batteries.
Physical and electrochemical characterizations demonstrate that the tap density of mixed powders with different particle sizes is higher than those of materials with a single particle size. The tap density of as-prepared material has a decreasing trend with the increase of the ratio of 9 μm sized particle in the materials.
Most importantly, the tap density of the anode material directly affects the energy density, volume, cycle life, and other performance of the LIBs.
