gels - 2025 Chicago Open - Buzzpoints App

Question

To prevent spontaneous human combustion, wearable lithium-ion batteries use these materials as electrolytes. For 10 points each:

[10e] Name these colloids in which crosslinked polymers like agarose or polyacrylamide are swollen by solvents like water.

ANSWER: gels [or hydrogels]

[10h] Without a gel, a wearable battery needs a separator at the solid-electrolyte interface, which is usually a layer of this polymer. This piezoelectric plastic is woven or electrospun to make wearable pressure sensors.

ANSWER: PVDF [or polyvinylidene fluoride; or polyvinylidene difluoride]

[10m] To achieve high conductivity at the cathode interface, many wearable batteries dope PVDF composites with one of these minerals like LLZO. One of these minerals hosts neodymium in a popular lasing medium.

ANSWER: garnets [accept yttrium aluminum garnet or YAG or Nd:YAG; prompt on silicates or nesosilicates]
