Abstract
1. Литий-ионный аккумулятор (ЛИА), включающий герметичный корпус с крышкой, в котором размещен рулонный блок из одной или более пар положительных и отрицательных электродов, разделенных пористым сепаратором, пропитанным органическим электролитом, при этом рулонный блок из предварительно плотно намотанных на оправку электродов после снятия его с оправки подпрессован в поперечном направлении, а на торцах блока нанесено покрытие из меди или алюминиево-цинкового сплава, отличающийся тем, что пористые сепараторы в блоке выполняют функцию электродных подложек.2. ЛИА по п.1, отличающийся тем, что активные массы электродов обоих знаков нанесены на подложки только с одной стороны подложки.3. ЛИА по п.1, отличающийся тем, что в активные массы положительных электродов известных составов на этапе приготовления суспензий дополнительно введены не окисленные частицы алюминия с размерами от 0,1 до 10 мкм в количестве не менее 0,0025 г/смпокрываемой поверхности.4. ЛИА по п.1, отличающийся тем, что в активные массы отрицательного электрода известных составов на этапе приготовления суспензий дополнительно введены не окисленные частицы металлов с размером от 0,1 до 10 мкм, алюминия в количестве не менее 0,0025 г/смпокрываемой поверхности для электродов на основе нанотитаната лития и меди в количестве не менее 0,0135 г/смпокрываемой поверхности для электродов на основе углерода, кремния или их смеси.5. ЛИА по п.1, отличающийся тем, что пары электродов различных знаков собраны в блок сторонами, обратными сторонам, на которые нанесены слои активных масс.6. ЛИА по п.5, отличающийся тем, что электроды различных знаков, не имеющих закраин, в сборке смещ�1. A lithium-ion battery (LIB), including a sealed case with a cover, in which a roll block of one or more pairs of positive and negative electrodes is placed, separated by a porous separator impregnated with an organic electrolyte, while a roll block of electrodes previously tightly wound onto a mandrel after removing it from the mandrel, it is pre-pressed in the transverse direction, and a coating of copper or aluminum-zinc alloy is applied to the ends of the block, characterized in that the porous separators in the block perform the function of electrode substrates. 2. LIB according to claim 1, characterized in that the active masses of the electrodes of both signs are applied to the substrate on only one side of the substrate. LIB according to claim 1, characterized in that in the active masses of positive electrodes of known compositions at the stage of preparing suspensions, unoxidized aluminum particles with sizes from 0.1 to 10 μm are additionally introduced in an amount of at least 0.0025 g / cm of the surface to be coated. LIB according to claim 1, characterized in that in the active masses of the negative electrode of known compositions at the stage of preparation of suspensions, non-oxidized metal particles with a size of 0.1 to 10 μm, aluminum in an amount of at least 0.0025 g / cm of the surface to be coated are additionally introduced for electrodes based on lithium and copper nanotitanate in an amount of not less than 0.0135 g / cm2 of the coated surface for electrodes based on carbon, silicon or their mixture. 5. LIB according to claim 1, characterized in that pairs of electrodes of different signs are assembled into a block by the sides, opposite sides, on which layers of active masses are applied. LIB according to claim 5, characterized in that the electrodes of different signs without edges in the assembly are displaced
