Embodiment 1
[0030] Example 1: Preparation of alkali-resistance composite collector plate
[0031] Treatment of the porous stainless steel plate: use 304 porous stainless steel as the substrate, prepare a collector plate with a diameter of 40 mm, a pore diameter of 0.3 mm, and a thickness of 0.5 mm, tie the edge of the porous stainless steel plate with a polytetrafluoroethylene tape, and use HNO3 solution (1mol / L), NaOH solution (1mol / L), deionized water and absolute ethanol were cleaned in an ultrasonic cleaner, and then stored in absolute ethanol.
[0032] Suspension preparation: Add sintered colloidal ceramic powder (AREMCO) into deionized water to prepare 30ml of suspension with a concentration of 0.35-0.52g / mL, shake evenly with an oscillator and add 0.5wt%-1wt% of silane coupling Agent (AP-TMS) and alkaline catalyst (KF), fully shaken by ultrasonic cleaning agent, mixed evenly, and then pulled at room temperature.
[0033] Pulling film formation: After the treated stainless steel ca...
Embodiment 2
[0035] Embodiment 2: test of reforming reaction containing alkali outside the pool
[0036] The purpose of this application test is to detect the ability of the alkali-resistant composite collector plate to block liquid molten carbonate. By simulating the battery structure and environment, the test is carried out in a special stainless steel tubular reactor. First, weigh 4 grams of porous alumina pellets and place them in the lower chamber of the reaction tube, and then place the current collector plate (with a pore diameter of 2 mm) used in the traditional fuel cell, the blank porous stainless steel current collector plate (with a pore diameter of 0.35 mm) and the resistor Alkali composite current collectors are respectively placed in the reaction tube, the single-layer electrolyte diaphragm (lithium metaaluminate film) used in the battery is cut to the same size as the current collector, and then the mixed alkali of 62mol% Li2CO3 and 38mol% K2CO3 2 grams of powder was placed...
