    摘要: Various systems and methods are presented in which lead acid batteries are serviced by removal, reconditioning, and refilling reconditioned battery paste into an assembly of typically bipolar electrodes that may be retained in a reusable housing and/or compression mechanism. Preferably, such batteries will include electrodes having a layer of a Magneli phase of a transition metal suboxide to so provide enhanced electrochemical and mechanical strength, and the battery paste may further include porous particles a Magneli phase of a transition metal suboxide to so provide enhanced electrolyte performance.

    摘要: An electrochemical cell including a can defining a lumen, an electrode assembly, a current collector and an insulator is provided. The current collector includes an attachment portion for coupling to the electrode assembly and a current collector strap. The insulator comprises a disc defining a first aperture sized such that the current collector strap is capable of extending through the first aperture. The insulator further comprises a first guide portion including a first arcuate surface for controlling a first bend radius of the current collector strap. Further, the insulator is press-fitted into the lumen to prevent the electrode assembly from pistoning.
