For the development trend of new energy vehicles, the biggest difficulty that needs to be overcome is the cruising range, and the length of the cruising range mainly depends on the power and energy consumption of the car. Generally speaking, if the total energy consumption is not considered, when the battery volume and mass are the same, the maximum mileage of a new energy vehicle is determined by the specific energy of the battery.
What is the energy density of lithium batteries?
The energy density of lithium batteries is the electromagnetic energy stored by the battery under a certain volume or mass.
The energy density of lithium batteries, that is, the average mass of the rechargeable battery stored by electromagnetic energy, is watts per kilogram (wh/kg);
The energy density of a lithium battery, that is, the average volume of a rechargeable battery stored in electromagnetic energy, is one watt/liter (wh/l).
Simply put, the higher the energy density, the more electricity can be stored.
There are actually two definitions of rechargeable battery energy that are usually mentioned.
Cell energy density
The battery structure of new energy vehicles is a battery pack composed of multiple batteries. Each battery pack is composed of multiple lithium-ion batteries, which is the basic module of the lithium-ion battery system.
System energy density
In contrast to energy, system software is the energy stored in the mass or volume of the entire battery system. Generally, the specific energy of a battery car battery is defined as the specific energy of the battery system. The rechargeable battery system is composed of many individually produced lithium-ion batteries, but due to the certain quality and space of the intelligent management system of rechargeable batteries and various connecting materials, the entire rechargeable battery system is generally lower than a single lithium-ion system.
What are the limitations on battery system energy density?
Battery system energy density = cell energy density × group efficiency
As mentioned above, rechargeable battery systems are composed of many lithium-ion batteries and are affected by the emergence of lithium ions and the connection of raw materials.
From lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride rechargeable batteries, nickel-cadmium batteries, nickel-metal hydride rechargeable batteries, lithium-ion batteries, automotive power lithium-ion batteries are increasing compared with energy sources. A lithium-ion battery consists of several parts of the lithium-ion battery, a protective film and an electrolyte. In the area where the lithium-ion battery slides in and out, the lithium-ion battery slides away from the battery's cathode material as the battery charges. Depending on the lithium-ion battery's electrolyte, the electronics flow into the cathode material, which slides from the negative to the positive electrode as the lithium-ion battery charges. In other words, the entire process of charging a lithium-ion battery is essentially the entire process of migration of the lithium-ion battery in the cathode material. Therefore, the basic theoretical volume of the positive battery cathode material determines the basic theoretical specific energy of lithium ions.
In addition to the lithium-ion battery chemistry system, the efficiency of the battery pack also affects the specific energy of the system. Efficient integration is key to battery system software space utilization and quality decisions for various connection materials. What the battery looks like will determine whether the classification is inseparable. For example, for irregular rechargeable battery shells, cylindrical rechargeable batteries can change the distance between lithium ions and have greater space utilization, making the module grouping more effective. The square lithium-ion core is more suitable for standard housings, reducing indoor space consumption. In addition, according to the design of improved contact groups and thermal management systems, lithium-ion core sorting can be more closely connected to improve the space utilization of the system. In addition, the thickness and density of various connecting materials will also affect the energy ratio. Generally speaking, the smaller the thickness and density of the material, the lighter the weight of the charging system and the higher the specific energy.
