Methods are described for the production of hydrogen-bis(chelato)borates of the general formula H[BL<1>L<2>] and of alkali metal-bis(chelato)borates of the general formula M[BL<1>L<2>] where M=Li, Na, K, Rb, Cs L<1>=-OC(O)-(CR<1>R<2>)n-C(O)O- or -OC(O)-(CR<3>R<4>)-O- where n=0 or 1, R<1>, R<2>, R<3>, R<4 >independently of one another denote H, alkyl, aryl or silyl, L<2>=-OC(O)-(CR<5>R<6>)n-C(O)O- or -OC(O)-(CR<7>R<8>)-O- where n=0 or 1, R<5>, R<6>, R<7>, R<8 >independently of one another denote H, alkyl, aryl or silyl, wherein the respective raw materials are mixed in solid form without the addition of solvents and are reacted. Lithium-bis(oxalato)borate, lithium-bis(malonato)borate, caesium-bis-(oxalato)borate, caesium-bis-(malonato)borate and the mixed salts lithium(lactato,oxalato)borate and lithium(glycolato,oxalato)borate for example may be produced in this way.
