Method for monitoring an electrochemical cell or a battery (), in particular method for monitoring the first charging of an electrochemical cell or of a battery () of Li-ion type, comprising a step of acquiring data relating to acoustic emissions produced in the electrochemical cell or in the battery and, by using the data acquired, a step of detecting:

Method for monitoring a Li-ion battery and monitoring device for the implementation thereof

An electrochemical cell comprises an inlet and an outlet for an electrolyte flow, and two unipolar electrodes. Each electrode comprises a structure with a network of through-passages, surrounded by a solid frame. The electrolyte enters via inlets, circulates via the passages of the electrodes, passes through the space between the electrodes and leaves via an outlet. The structure and the frame are based on carbon.

Electrochemical cell with an electrolyte flow, comprising through-electrodes and production method

A structure including a network of parallel, homogeneous pores extending through the structure, and an outer frame around the lateral faces of the structure. The structure and the frame are made of carbon. The electrode is covered by a layer based on lead. The pores are filled with an active material based on lead.
