Patent attributes
A lithium anode containing spherical lithium metal particles with an average diameter of between 5 and 200 μm, which are bonded with a fluorine-free rubber-like binding agent from the groupssaturated polyolefins and polyolefin copolymers, such as EPM (ethylene-propylene copolymers), EPDM (ethylene-propylene terpolymers) and polybutenesunsaturated polymers (diene polymers and diene copolymers), such as natural rubbers (NR), butadiene rubbers (BR), styrene-butadiene rubbers (SBR), polyisoprene rubbers and butyl rubbers (IIR, such as polyisobutylene isoprene rubber, PIBI) as well asheteroelement-containing copolymers, for example saturated copolymer rubbers, such as ethylene vinyl acetate (EVM), hydrogenated nitrile-butadiene rubber (HNBR), epichlorhydrin rubber (ECO), acrylate rubbers (ACM) and silicon rubbers (SI), as well as unsaturated copolymers, such as nitrile rubbers (NBR), for example,as well as galvanic cells containing the bonded lithium anode according to the invention and method for producing the bonded lithium anode.
