Abstract
1. Химический источник электрической энергии, который содержит положительный электрод (катод), содержащий серу или органические соединения на базе серы, полимерные соединения на базе серы или неорганические соединения на базе серы в качестве деполяризатора, отрицательный электрод (анод), изготовленный из металлического лития или из содержащих литий сплавов, и электролит, содержащий раствор по меньшей мере одной соли по меньшей мере в одном апротонном растворителе, причем химический источник электрической энергии вырабатывает растворимые полисульфиды в электролите во время первой стадии двухстадийного процесса разрядки, отличающийся тем, что количество серы в деполяризаторе и объем электролита выбраны так, что после первой стадии разрядки катода концентрация растворимых полисульфидов лития в электролите составляет по меньшей мере 70% концентрации насыщения полисульфидов лития в электролите. ! 2. Химический источник электрической энергии по п.1, в котором количество серы в деполяризаторе и объем электролита выбраны так, что после полной разрядки катода концентрация растворимых полисульфидов лития в электролите составляет от 70 до 90% концентрации насыщения полисульфидов лития в электролите. ! 3. Химический источник электрической энергии по п.1, в котором деполяризатор содержит серу, углеродную сажу и полиэтилен оксид. ! 4. Химический источник электрической энергии по одному из пп.1-3, в котором электролит содержит раствор одной или нескольких солей лития, выбранных из группы, в которую входят трифторметансульфонат лития, перхлорат лития, трифторметансульфонимид лития, гексафторфосфат лития, гексафторарсен�1. A chemical source of electrical energy that contains a positive electrode (cathode) containing sulfur or sulfur-based organic compounds, sulfur-based polymer compounds or sulfur-based inorganic compounds as a depolarizer, a negative electrode (anode) made of lithium metal or of lithium-containing alloys, and an electrolyte containing a solution of at least one salt in at least one aprotic solvent, and the chemical source of electrical energy generates soluble polysulfides in the electrolyte during the first stage of a two-stage discharge process, characterized in that the amount of sulfur in the depolarizer and the electrolyte volume is chosen so that after the first stage of cathode discharge, the concentration of soluble lithium polysulfides in the electrolyte is at least 70% of the saturation concentration of lithium polysulfides in the electrolyte. ! 2. The chemical source of electrical energy according to claim 1, in which the amount of sulfur in the depolarizer and the volume of the electrolyte are selected so that after the cathode is completely discharged, the concentration of soluble lithium polysulfides in the electrolyte is from 70 to 90% of the saturation concentration of lithium polysulfides in the electrolyte. ! 3. The chemical source of electrical energy according to claim 1, wherein the depolarizer comprises sulfur, carbon black, and polyethylene oxide. ! 4. A chemical source of electrical energy according to one of claims 1 to 3, in which the electrolyte contains a solution of one or more lithium salts selected from the group consisting of lithium trifluoromethanesulfonate, lithium perchlorate, lithium trifluoromethanesulfonimide, lithium hexafluorophosphate, hexafluoroarsen�
