AI Technical Summary
Existing nonaqueous alkali metal power storage elements face challenges with ion diffusion resistance and increased electron transfer resistance at high temperatures, and existing positive electrode coating liquids do not adequately enhance energy density and output characteristics.
A nonaqueous alkali metal power storage element with a positive electrode coating liquid containing single-wall carbon nanotubes, which reduces ion diffusion resistance and suppresses electron transfer resistance at high temperatures, while improving energy density and output characteristics through controlled content of carbon nanotubes in the positive and negative electrodes.
The solution results in a nonaqueous alkali metal power storage element with reduced ion diffusion and electron transfer resistance, high energy density, and enhanced input/output characteristics, along with improved durability at high temperatures and voltages.
