A non-aqueous electrolyte usable in rechargeable lithium-ion batteries including a solution of LiPF6carbonate based electrolytes with low concentrations of LiFOP such that the thermal stability is increased compared to a standard lithium battery. The second magnetic field is used to provide the power to recharge the battery. The method of retrofitting comprises fixedly securing a sealing member to the stator. A gate electrode is formed in the trench over the shield electrode, and an interconnect layer connecting the gate electrode and the shield electrode is formed. A set screw is operable to clamp the rod against the sleeve and draw the insert into engagement within the socket.
