Abstract

Sposób wytwarzania kolektora prądowego kompozytowego akumulatora ołowiowo-kwasowego przedstawiony na rysunku, który to kolektor posiada podłoże z porowatego nieołowiowego materiału przewodzącego, pokryte co najmniej częściowo warstwą ołowiu lub stopu ołowiu, i posiada wyprowadzenie elektryczne, charakteryzuje się tym, że wykonuje się podłoże z porowatego nieołowiowego materiału przewodzącego o określonej, docelowej geometrii, wymiarach, kształcie, architekturze przestrzennej i reliefie oraz porowatości, w sposób niewymagający obróbki mechanicznej materiału docelowego, z którego wykonane jest podłoże. Podłoże kolektora prądowego posiada relief w postaci zagłębień o określonej głębokości, tworzących wzór na co najmniej jednej jego płaszczyźnie bocznej. Ponadto, podłoże posiada architekturę przestrzenną w postaci kanałów o określonych wymiarach i kształcie, które przechodzą przez nie na wylot. Podłoże ma dowolny kształt, przykładowo prostopadłościennej cienkiej płytki, lub kształt okrągły. Podłoże jest zmodyfikowane poprzez dodatnie wypustu służącego do wykonania wyprowadzenia elektrycznego. Podłoże kolektora prądowego uzupełnia się o dodatkowe elementy zwiększające jego odporność mechaniczną lub przewodnictwo elektryczne, poprzez wpasowanie ich w relief podłoża. Porowate podłoże wykonane jest z nieołowiowego materiału przewodzącego, na przykład zwęgla przewodzącego, węgla szklistego, miedzi, niklu, chromu, tytanu, albo węgla przewodzącego pokrytego warstwą miedzi, niklu, chromu lub tytanu, albo z węgla szklistego pokrytego warstwą miedzi, niklu, chromu lub tytanu. Podłoże pokrywa się warstwą ołowiu lub jego stopu. Sposób według zgłoszenia umożliwia wytwarzanie lekkich węglowych kolektorów prądowych, które są wolne od mikropęknięć i mikrouszkodzeń, a co za tym idzie wykazują większą odporność mechaniczną, zwiększone przewodnictwo podłoża kolektora prądowego oraz lepsze wykorzystanie masy czynnej podczas pracy akumulatora. Dzięki zastosowaniu sposobu według zgłoszenia, jest możliwe wykonanie kompozytowego akumulatora ołowiowo-kwasowego typu CLAB o dowolnym kształcie i zastosowaniu.The method of producing a current collector for a composite lead-acid battery is shown in the figure, which collector has a substrate of porous, non-lead conductive material, covered at least partly with a layer of lead or lead alloy, and has an electrical lead, characterized by a substrate made of porous, non-lead conductive material with specific target geometry, dimensions, shape, spatial architecture and relief, and porosity in a way that does not require mechanical treatment of the target material from which the substrate is made. The current collector's ground has a relief in the form of depressions of a certain depth, forming a pattern on at least one of its lateral surfaces. In addition, the substrate has spatial architecture in the form of channels of specific dimensions and shape that pass through it. The substrate has any shape, for example a rectangular thin plate, or a round shape. The substrate is modified by a positive spline to make an electrical lead. The current collector surface is supplemented with additional elements increasing its mechanical resistance or electrical conductivity by fitting them into the surface relief. The porous substrate is made of non-lead conductive material, e.g. conductive carbon, glassy carbon, copper, nickel, chromium, titanium, or conductive carbon coated with a layer of copper, nickel, chromium or titanium, or glassy carbon coated with a layer of copper, nickel, chromium or titanium. The substrate is covered with a layer of lead or its alloy. The method according to the application enables the production of lightweight carbon current collectors, which are free from microcracks and microdamages, and thus show greater mechanical resistance, increased conductivity of the current collector substrate and better use of active mass during battery operation. By using the method according to the application, it is possible to make a composite lead-acid battery type CLAB of any shape and use.
