The invention „Effiziente H2O-division“ refers to the synthesis of a noble metal- free mixtureoxidcatalyst by deposition of transition metal oxides on a n- semiconducting material. These quaternary catalyst systems show activity and stability in the photocatalytic cleavage of water, which is compara.....

The invention chemical overcharge protection describes carbene complexes which are found within a lithium-ion battery above a determined charge potential, e.g. when overcharging the battery, decompose. The accumulator is thus protected due to the chemical additive in the electrolyte from overheating.....

The invention describes an additive for electrolytes for use in lithium-ion batteries. The substance cis-4,5-bis (trifluoromethyl) -1,3-dioxolan-2-one according to the invention makes it possible to use the solvent propylene carbonate, which results in a reduced safety risk compared to conventional .....
