At present, all lithium batteries use multiple single lithium batteries to form the required voltage and capacity;
For example, the single 18650 lithium battery is 3.5 V, 2500 mAh and 12 V requires 3-4 batteries. lithium batteries can be connected in series to meet voltage requirements; 30 Ah requires 12 sets of 12V batteries connected in series and parallel to meet capacity requirements.
For reference.
Is it possible to use 9 soft cells to make a 12 volt battery?
The processing technology of lithium-ion batteries is very strict and complex. We can only briefly present it here. some of the main processes. (1) Special solvents and binders are used for mixing sludge with powder positive and negative electrode active materials respectively, and after high-speed uniform mixing,Mud-type positive and negative electrode materials are manufactured.
(2) Coating film: Apply the prepared suspension evenly to the surface of the metal sheet, dry it, and make positive and negative electrode plates respectively.
(3) The assembly is placed in the order positive electrode sheet - separator - negative electrode sheet - separator from top to bottom, and is rolled into a battery core, which is then injected with electrolyte, sealed, etc. The process involves completing the battery assembly process and manufacturing the finished battery.
(4) The chemical industry uses special battery charging and discharging equipment to carry out charging and discharging tests on finished batteries, inspect each battery, and select qualified finished batteries before leave the factory.
Yes. A 12 volt battery can be made up of 9 soft-packaged cells. The coreof the battery is a lithium polymer battery, commonly known as a soft-pack lithium battery. It is the electrical telecommunications used in electric vehicles. The production method is as follows: 3 18650 lithium batteries are connected in parallel to form 1 group. 9 18650 lithium batteries can be made into 3 groups. Then 3 groups can be connected in series to form a battery pack of around 12V.
