摘要:
An apparatus and method for reducing differential cross-talk in a pin arrangement of a socket are described. Socket pins within a differential pair use a modified shape to tighten the intra-pair pin coupling to reduce the crosstalk without changing the pin map. The middle vertical segment of one pin of a diagonally adjacent differential pin pair is modified to be closer to the other pin than other corresponding locations of the pins. The spring beam that extends from the middle vertical segment of the one pin is modified to accommodate the package landing pad that the spring beam contacts to maintain a uniform pitch.

A lithium-ion battery comprises a positive electrode, a negative electrode, an electrolyte system and an ion-selective conducting layer disposed between the positive electrode and the negative electrode. The ion-selective conducting layer consists of high polymers and an inorganic lithium salt having lithium-ion conductivity, or consists of the inorganic lithium salt. The inorganic lithium salt includes LimMnOx, wherein the values of the m and n ensure the LimMnOx an electrically neutral compound, M is selected from at least one of B, P, Si, Se, Zr, W, Ti, Te, Ta, Al and As. The lithium-ion battery has a conduction layer having preference-selective conductivity for the lithium ions and disposed between the positive electrode and the negative electrode. The selective-conduction layer has improved mobility for lithium ions. Metal ions generated from the oxidized metal current collector at the negative electrode due to the over-charging of the battery can be blocked.
