    Abstract: A cell carrier for a battery module, a battery module, and a method for assembling a battery module. The battery module includes a plurality of pairs of battery cells and the cell carrier. The cell carrier includes a plurality of recesses, each including a first recess portion including a first sidewall portion and a first bottom portion, and a second recess portion including a second sidewall portion and a second bottom portion. The first bottom portion and the second bottom portion of each recess include a shared cutout. For each pair of battery cells, a first end of a first battery cell is coupled to the first recess portion and a first end of a second battery cell is coupled to the second recess portion of a respective recess.

    Abstract: This application provides a battery module and a vehicle. The battery module includes a plurality of battery cells. Each battery cell includes a battery top cover; a thermally conductive sampling piece, fitting snugly with the battery top cover; a thermally conductive connecting plate, where one end of the thermally conductive connecting plate fits snugly with the thermally conductive sampling piece; a circuit board, disposed above the battery top cover, where another end of the thermally conductive connecting plate is connected to the circuit board; and a thermometric element, electrically connected to the circuit board. The thermometric element is configured to collect a temperature signal of the thermally conductive connecting plate and transmit the temperature signal to the circuit board. The battery module provided in this application facilitates real-time and accurate collection of battery temperatures.

    Abstract: The present disclosure provides a wound-type cell and a preparation method thereof, a battery, and an electronic product. The wound-type cell includes a positive sheet, a negative sheet, and an insulated separator located between the positive sheet and the negative sheet; the negative sheet includes a negative base layer, a negative coating, and a negative tab set on the surface of the negative base layer. The negative coating covers surface of the negative base layer, and the negative coating has a tab connection area that avoids the negative tab. The negative tab is located in the tab connection area; the insulated separator between the tab connection area and the positive sheet is provided with a barrier layer covering the tab connection area. The provided solutions are helpful to reduce safety risks caused by lithium-plating during the fast charging of lithium ion battery.

    Abstract: The invention relates to a method of recycling lithium iron phosphate batteries with the aim of enabling the isolated recovery of elements from black mass. Black mass comprising at least cathodic and anodic components is immersed in a pH 13-14 solution to obtain a first leachate and first solid residue. The first leachate is immersed in a 4-6M acid solution to obtain a second leachate. The second leachate is passed through a first ion-exchange column where fluoride ions are retained and a second ion-exchange column where copper ions are to obtain a second eluate. The pH of the second eluate is adjusted to about 2.5-5 and a quantity of phosphoric acid that is sufficient to achieve an equivalent stoichiometric ratio of ferric iron and phosphate anions is added to obtain a first solution and an iron (III) phosphate precipitate. The first solution is combined with the first leachate to obtain a second solution. The pH of the second solution is adjusted to about 6.5 to a residual precipitate and a lithium solution.
