18650 battery cell.
Stellar lithium batteries are not 18650 cells. They are generally 3.2v10a to 50a lithium iron phosphate batteries and ternary lithium batteries 3.7v10a to 50a.
Starway lithium batteries have a relatively long lifespan, which can reach more than six years. They have high power endurance, facilitate high-current startup acceleration, and have a low self-discharge rate and no memory effect. . Compared to batteries, lithium batteries have high energy density. It has a high storage energy density, currently reaching 460-600 Wh/kg, approximately 6-7 times that of lead-acid batteries.
As the main component of power battery, battery core plays an important role in power battery. For the battery, the battery core determines the quality and product quality ofthe battery, and of course it does. also linked to the vehicle battery. Does battery life and capacity, for essential battery components, mean battery cell equals battery?
Cells and batteries are two different concepts. To put it simply, a battery is like a container that stores electrical energy, and the battery core is a big model in the big battery concept. Battery component, taken alone, the battery core is equivalent to a semi-finished product and cannot be used directly as a battery.
According to the composition of the battery core, the battery core contains positive and negative electrochemical components and is not used directly. It only provides energy, but if it wants to become a finished product, then this object must be equipped with a protection circuit, and then on this basis, a series of components such as the coque are added, so that it can be a finished lithium battery. According to the structure of the battery core, the battery core is not equal to the battery in the battery.
Summary: For electric vehicles, the battery and the cell are two different things, and they interact with each other. However, as the core component of the battery, from the perspective of cell structure look, the battery cells are connected in series through various circuits without protective plates inside the battery, and the battery is the battery core + protection plate, so the battery contains the cells taken together, electric vehicle battery cells are not equal to the battery. .
