Serviceable Batteries with Reusable Electrodes
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.
SHORT-CIRCUIT PROTECTION IN WET-CELL BATTERY
A wet cell battery, where a first cell in a wet-cell battery includes a set of anode electrodes and a set of cathode electrodes, and where electrically conductive debris accumulates on a surface inside the first cell to an expected height. An anode electrode in the set of anode electrodes has an anode end closest to the surface, and a cathode electrode in the set of cathode electrodes has a cathode end closest to the surface. A first gap distance between the anode end and the surface is different from a second gap distance between the cathode end and the surface. When the electrically conductive debris accumulates up to the expected height, the debris fails to make simultaneous electrical contact with the anode electrode and the cathode electrode due to the different gap distances.
ENERGY STORAGE DEVICE HAVING SEPARATOR AND MUD REST FLUID FLOW PATH FEATURES
An energy storage device is disclosed that in one embodiment is a rechargeable battery. The device includes a container within which is disposed battery plates, separators, and battery fluid. A mud well having mud rests is also disposed within the container. The separator can be formed as a pocket for insertion of a battery plate. The separator can include channel features sized to convey a gaseous byproduct of a charging event of the battery. In one form the mud rests define passages, such as an internally formed passage, that assist in the circulation of battery fluid.
Pasting paper made of glass fiber nonwoven comprising carbon graphite
Embodiments of the invention provide a lead-acid battery having a positive electrode, a negative electrode, and a separator positioned between the electrodes to electrically insulate the electrodes. Battery includes a nonwoven fiber mat positioned adjacent an electrode. Mat includes a mixture of first glass fibers having diameters between 8 m to 13 m and second glass fibers having diameters of at least 6 m and a silane sizing. An acid resistant binder bonds the glass fibers to form mat. A wetting component is applied to increase the wettability such that mat exhibits an average water wick height of at least 1.0 cm after exposure to water for 10 minutes. A conductive material is disposed on a surface of mat such that when mat is adjacent an electrode, the conductive material contacts the electrode. An electrical resistance of less than 100,000 ohms per square enables electron flow about mat.
