Abstract: A portable power bank including a rechargeable battery may detect loss of capacity in the power bank battery. The power bank determines a nominal capacity of the power bank, and an actual capacity of the power bank, the actual capacity being less than the nominal capacity. The power bank compares the actual capacity to the nominal capacity to determine a health value of the power bank battery. When the power bank battery health value is at or below a threshold value, the power bank transmits an indication of the health value to a mobile computing device.

Abstract: A portable power bank including a rechargeable battery and/or a remote server may detect loss of capacity in the power bank battery. The power bank and/or remote server determines a nominal capacity of the power bank, and an actual capacity of the power bank, the actual capacity being less than the nominal capacity. The power bank and/or remote server compares the actual capacity to the nominal capacity to determine a health value of the power bank battery. When the power bank battery health value is at or below a threshold value, the power bank and/or remote server transmits an indication of the health value.

Abstract: The invention is directed towards a battery. The battery includes a cathode, an anode, a separator between the cathode and the anode, and an electrolyte. The cathode includes a conductive additive and an electrochemically active cathode material. The electrochemically active cathode material includes a beta-delithiated layered nickel oxide. The beta-delithiated layered nickel oxide has a chemical formula. The chemical formula is LixAyNi1+a−zMzO2.nH2O where x is from about 0.02 to about 0.20; y is from about 0.03 to about 0.20; a is from about 0 to about 0.2; z is from about 0 to about 0.2; and n is from about 0 to about 1. Within the chemical formula, A is an alkali metal. The alkali metal includes potassium, rubidium, cesium, and any combination thereof. Within the chemical formula, M comprises an alkaline earth metal, a transition metal, a non-transition metal, and any combination thereof. The anode includes an electrochemically active anode material. The electrochemically active anode material includes zinc, zinc alloy, and any combination thereof.

Abstract: A seal assembly for a battery cell includes a grommet having an opening having an inner surface. A nail has a nail head and a stem extending from the stem. The stem includes a first portion with a larger diameter and a second portion with a smaller diameter and the stem extends through the opening in the grommet. The stem and the grommet form a first interference fit at a distal end of the opening. A trap clearance is formed between the distal end of the opening and the nail head. The trap clearance defines a trap for a sealant. A sealant is disposed on the stem and is located at least partially in the trap.
