1.5v dry cell battery

release time:2024-06-05 Hits:     Popular:AG11 battery

Japan develops new raw materials for 1.5v dry cell battery

 

According to foreign media reports, researchers at the National Institute for Materials Science (NIMS) of Japan claimed that nanoporous amorphous silicon film anodes showed excellent cycle stability and extremely high lithium ion storage capacity: 2962mAh/g (2.19mAh/cm2) after 100 charge and discharge cycles.

 

The NIMS team combined nanoporous amorphous silicon film with inorganic solid electrolyte to solve the problem of capacity fading. The nanoporous structure can adapt to the volume change of silicon, thereby limiting the mechanical fracture and pulverization of the anode.

 

Unlike liquid electrolytes, solid electrolytes do not decompose because their electrochemical stability window is wider. Experiments have shown that silicon materials have a higher capacity, and even if they are charged and discharged 100 times, the capacity decay is small.

 

The research received financial support from the New Energy and Industrial Technology Development Organization (NEDO) and Toyota Motor Corporation.
