Abstract
Abstract The invention relates to electrochemical cells intended to be electrically connected up in series. Such a connection is obtained by means of a mechanical link between the terminals of opposite polarities of two adjacent cells. That mechanical link may be formed by a spring-catch system, screwing or locking. The invention applies more particularly to cylindrical electric cells.
