Que signifie la densité d'énergie d'une batterie au lithium?

Avec le développement de la société, les gens peuvent voir des produits de batterie au lithium partout , de plus en plus indissociable de la batterie au lithium, maintenant les fabricants de batteries doivent surmonter la plus grande difficulté est la durée de vie de la batterie, durée de vie, mais la longueur de la gamme dépend principalement de l'équipement électronique et de la consommation d'énergie, en général, si l'on ne considère pas la consommation totale d'énergie, when the battery volume and quality of the same condition, the length of the life is determined by the battery than energy size.So what is the lithium battery energy density?Let’s take a look at …

What does the energy density of a lithium battery mean？

Basically, the energy density of lithium battery is the electromagnetic energy that can be stored under a certain volume or mass conditions. The energy density of lithium battery, namely the average value of charging battery quality, is stored by electromagnetic energy, in watt / kg (wh / kg) The energy density of a lithium battery is stored on average in electromagnetic energy in watt / liter (wh / L). Simply put, the greater the battery energy density, the larger the stored battery.

Energy density of cell

The rechargeable battery structure of electronic devices is designed as a battery pack composed of several rechargeable batteries, and each rechargeable battery touch pack is composed of several lithium-ion batteries, namely the basic module of lithium-ion battery system software.

System software energy density

In contrast to the energy, the system software is the energy stored in the mass or volume of an entire battery system software.Generally speaking, the specific energy of the battery car rechargeable battery is understood as the specific energy of the rechargeable battery system software.Rechargeable battery system software is composed of many independently produced lithium ion batteries, but considering that the intelligent management system of rechargeable batteries and various connected raw materials has a certain quality and space environment, a whole rechargeable battery system software can not reach the single lithium ion system software.

What are the limitations on the energy density of battery system software? Battery system energy density = cell energy density into group efficiency As mentioned above, the rechargeable battery system software consists of many batteries lithium-ion, affected by the emergence of lithium ions and the connection of raw materials.
