Abstract:
PURPOSE: A method for evaluating skin irritation is provided to express skin sensitivity and irritation and to replace a conventional skin stimulation test. CONSTITUTION: A method for evaluating/predicting skin irritation comprises: a step of treating a test material to organ-derived nerve cells; a step of measuring cell membrane ion potential of the nerve cells; and a step of confirming stimulation. The nerve cells are afferent sensory nerve cells or neuron. A kit for evaluating the skin irritation comprises the nerve cells and micro current measuring device.
Abstract:
본발명은급속충방전이가능한나트륨바나듐인산염계전극활물질의제조방법및 그방법으로제조된이차전지용나트륨바나듐인산염계전극활물질에관한것으로, 보다구체적으로는나트륨이온전지의전극활물질이갖는단점을극복하기위해나트륨전극소재와인화니켈과의복합체를구성함으로써급속충방전이가능한나트륨바나듐인산염계전극활물질의제조방법에관한것이다. 본발명의제조방법에의하면나트륨바나듐인산염계전극소재와전기전도도가우수한인화니켈과의복합체를구성함으로써급속충방전이가능한나트륨바나듐인산염계전극활물질을제조할수 있다. 또한, 본발명에의해제조된나트륨바나듐인산염계전극활물질은고출력특성을발현하는나트륨이차전지에적용할수 있는효과가있다.
