Abstract: The present invention relates to a lithium transition metal composite oxide capable of being used as a positive electrode (cathode) active material for non-aqueous electrolyte lithium secondary batteries having a general formula Li1+a(1?x?y?z)M1xM2yM3(1?a)(1?x?y?z)M3?a(1?x?y?z)M4zO2+a(1?x?y?z), in which 0.7?x<1, y=(1?x)/2, 0?z?0.05 and 0<a(1?x?y?z)?0.05, and where M1 is Ni having an oxidation state of three, M2 is one or more metal cations having an oxidation state of three, M3? and M3 are identically one or more metal cations with at least one ion being Mn, wherein the one or more metal cations M3 have an oxidation state of four and the one or more metal cations M3 have an oxidation state of three, and M4 is one or more metal cations selected from of Mg, Al and B. Further, the present invention relates and a method for preparing the lithium transition metal composite oxide and to a non-aqueous electrolyte lithium secondary battery containing the lithium transition metal composite oxide.

Abstract: A lithium rechargeable battery includes a positive electrode that intercalates and deintercalates lithium and a negative electrode that intercalates and deintercalates lithium and has a current collector including Cu or a Cu alloy. In addition, the battery includes a separator interposed between the positive electrode and the negative electrode, and an electrolyte that transfers lithium ions.

Abstract: The mechanical synchronized time-based mass flow controller can control the flow rate easily and precisely. The mechanical synchronized time-based mass flow controller includes a reservoir 1a, 1b, an inlet line 14, an outlet line 24, a valve 3 and a control unit. The valve 3 has a passage 3a through which the fluid passes and operates in a mechanical cycle which includes an inlet line open period when the passage 3a is communicated with the inlet line 14 and the inlet line 14 is in an open state and an outlet line open period when the passage 3a is communicated with the outlet line 24 and the outlet line 24 is in an open state according to change of position of the passage 3a, the inlet line open period and the outlet line open period coming out of phase with each other so that the inlet line 14 can be opened when the outlet line 24 is in a closed state and the outlet line 24 can be opened when the inlet line 14 is in a closed state.
