Abstract: An electronic device may include a battery, and a charging system in electronic communication with the battery. The charging system may be configured to initiate a charging of the batter when the battery is in a partially-depleted state. The charging system may then discontinue the charging in response to the battery being charged to the threshold charge value, and may monitor the function of the electronic device to predict an event of the electronic device. After the event is predicted, the charging system may determine when to initiate a recharging process, so that the battery is fully charged when the event occurs.

Abstract: Methods are presented for synthesizing a metal precursor for a cathode-active material. The methods include adding urea to a solution comprising dissolved ions of at least one transition metal selected from Mn, Co, and Ni. The methods also include increasing a pH of the aqueous solution to a threshold pH. The methods additionally include heating the aqueous solution to precipitate a compound that includes the at least one transition metal. Such heating may involve urea decomposition. Methods are also presented that include filtering the compound from the solution and contacting the compound with at least a lithium precursor to produce a reactant charge. In these methods, the reactant charge is calcined to produce the cathode-active material. Other methods are presented.

Abstract: The disclosed embodiments relate to the manufacture of a precursor co-precipitate material for a cathode active material composition. During manufacture of the precursor co-precipitate material, an aqueous solution containing at least one of a manganese sulfate and a cobalt sulfate is formed. Next, a NH4OH solution is added to the aqueous solution to form a particulate solution comprising irregular secondary particles of the precursor co-precipitate material. A constant pH in the range of 10-12 is also maintained in the particulate solution by adding a basic solution to the particulate solution.

Abstract: Methods and systems for detecting and compensating for expansion of rechargeable batteries over time. An expansion detector may be coupled to or positioned proximate a rechargeable battery to monitor for expansion thereof. After expansion exceeding a selected threshold is detected, the expansion detector may report the expansion to an associated processing unit. The processing unit may undertake to arrest further rechargeable battery expansion by modifying or changing one or more characteristics of charging and/or discharging circuitry coupled to the rechargeable battery. For example, the processing unit may charge the rechargeable battery at a lower rate or with reduced voltage after detecting expansion.
