On October 26, 2021, a BYD battery price increase contact letter was posted on the market. According to the letter, due to market changes and superimposed power and production restrictions, compared with December 2020, lithium battery raw materials will continue to rise in 2021. The price of cathode material LiCoO2 will increase by more than 200%, the price of electrolyte will increase by more than 150%, and the price of anode materials will increase by more than 150%. As the supply continues to be tight, the overall cost has increased significantly. According to the actual situation of rising raw material prices, the unit price of CO8M and other battery products will be increased after research.
As a portable energy storage device, lithium ion batteries are widely used in mobile phones, notebook computers, cameras, electric bicycles, electric vehicles and other fields. Among them, the lithium battery electrolyte is an aspect that cannot be ignored. After all, the electrolyte, which accounts for 15% of battery cost, does play a vital role in battery energy density, power density, wide temperature applications, cycle life and safety performance.
The size of the lithium ion polymer battery is directly related to the battery capacity. The formula for calculating the capacity of a lithium ion polymer battery is: capacity (AH) = constant discharge current (A) × discharge time (H). The battery on the mobile power supply usually uses a lithium polymer battery. The choice of lithium polymer battery mainly has several indicators to meet the demand. The main factors are high safety, many charge and discharge times, long life and large capacity. Next, let us take a closer look at how to calculate the capacity of lithium-ion polymer batteries.
Electrolyte is an important part of lithium-ion batteries. It not only transports and conducts current between the positive and negative electrodes, but also determines the working mechanism of the battery to a large extent, affecting the specific energy, safety performance, rate charge and discharge performance, cycle life and production cost of the battery.
The negative electrode of lithium ion battery is made by mixing the negative active material carbon material or non-carbon material, binder and additives to form a paste glue, evenly spreading it on both sides of the copper foil, drying and calendering it.
