The invention relates to a method and anode for improving power density of lithium secondary batteries, specially those containing solid polymer solutions. This is done by employing boric acid esters and/or boric acid derivatives or the compounds thereof as additives. Lithium compounds in corresponding complexes are specially added. The invention also includes anodes for use in galvanic cells, specially in lithium ion secondary batteries and those with solid polymer solutions, which contain boric acid esters and/or boric aid ester derivatives or the compounds thereof as additives in the anode.
L'invention concerne des procédés et une anode permettant d'améliorer la densité de puissance de batteries secondaires au lithium, notamment de batteries comprenant des solutions polymères solides. A cet effet, il est prévu d'utiliser comme additifs des esters d'acide borique et/ou des dérivés d'esters d'acide borique ou leurs composés. Des composés de lithium sont notamment ajoutés sous forme de complexes correspondants. L'invention concerne en outre des anodes s'utilisant dans des cellules galvaniques, notamment des batteries secondaires à ions de lithium et celles qui comprennent des solutions polymères solides contenant comme additifs, dans l'anode, des esters d'acide borique et/ou des dérivés d'esters d'acide borique ou leurs composés.
