Such batteries are more expensive than their counterparts.
But it is necessary to design a device with flat-shaped lithium batteries, which means that the battery will have a narrow, specialized application. All other things being equal, a flat lithium battery will be lighter, much more compact, and provide significant current (that is, more power). Therefore, the finished battery cell must be carefully sealed.Ī flat battery is simpler in design. And the ingress of moisture and does threaten the danger of fire and even explosion. The ingress of ambient air can upset the carefully balanced chemical balance. Therefore, in the design of lithium batteries, there is always a spring that compresses the “sandwich” from the anode, cathode and negative current collector. Current collection is carried out from a copper plate superimposed on the back of the cathode.įor normal battery operation, the porous cathode must be pressed tightly enough to the anode. Loose graphite or coke is suitable for it. The electrolyte impregnates a porous mass of electrically conductive chemically neutral material. The cathode is the electrolyte itself, which contains lithium salts in liquid form. The anode is made of a cobalt oxide film deposited on an aluminum base-current collector. This was a significant disadvantage of the batteries of the previous designs and led to a high probability of fire.

But the fundamental feature is the use of anhydrous electrolyte, which prevents the release of free hydrogen during operation. The design of a lithium rechargeable battery is not too different from the design of batteries based on other chemistry.
