CHEMICAL CELL Russian patent published in 2017 - IPC H01M6/20 

FIELD: electricity.

SUBSTANCE: in contrast to the known chemical cell (CC), comprising a unit of thermally activated ECEs, arranged in a cylindrical housing made with through vertical slots in the form of windows and equipped with a composite heat and electrical insulation, compressed along its vertical axis by a system of resilient and adjusting elements, wherein each ECE consists of a stack of successively alternating solid layers of an anode, an electrolyte, a cathode, and solid layers of pyrotechnic heating elements (PHEs) introduced between active-mass layers, a unit of ECEs, equipped with multi-pole current leads, a thermal activation system according to the invention, each ECE is made in the form of compacted solid layers of an anode represented by lithium-boron alloy with the boron content of not less than 28%, electrolyte layers in the form of the eutectic mixture of silicates and phosphates of alkali metals and a cathode consisting of the mixture of nickel chloride and vanadium oxide. In the cathode body, an expanded nickel mesh with a diameter in the range of 75% to 95% of the cathode diameter and having a thickness of 10% to 30% of the cathode thickness is pressed in, multi-pole current leads are output at the ends of the unit of ECEs from the extreme ECEs to the corresponding CC poles.

EFFECT: reducing the time of the cell switching into the operating mode, increasing the operation duration, increasing the reliability, reducing the internal resistance of electrochemical cells, increasing the voltage at impulse actuations.
