Introduction of common cylindrical lithium-ion battery models

Wednesday, December 1, 2021 7:27:00 PM America/Los_Angeles

Cylindrical lithium-ion batteries are usually represented by five digits. Counting from the left, the first and second digits are the diameter of the battery, the third and fourth digits are the height of the battery, and the fifth digit represents the cylindrical shape. There are many types of cylindrical lithium batteries, the more common ones are 10400, 14500, 16340, 18650, 21700, 26650, 32650 and so on.

The difference between cylindrical lithium battery and square lithium battery

Sunday, November 7, 2021 10:39:16 PM America/Los_Angeles

Cylindrical lithium batteries are divided into different systems such as lithium iron phosphate, lithium cobalt oxide, lithium manganate, cobalt-manganese hybrid, and ternary materials. The outer shell is divided into two types: steel shell and polymer. Different material systems have different advantages. At present, cylindrical batteries are mainly steel cylindrical lithium iron phosphate batteries, which are characterized by high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, large discharge current, stable electrochemical performance, safe use, and wide operating temperature range. Environmental protection, widely used in solar lights, lawn lights, backup energy, power tools, toy models.

What are the dismantling and recycling methods for lithium iron phosphate batteries?

Wednesday, November 3, 2021 12:17:18 AM America/Los_Angeles

The decommissioned lithium iron phosphate batteries and the batteries after the cascade use that do not have the value of cascade use will eventually enter the dismantling and recycling stage. The difference between a lithium iron phosphate battery and a ternary material battery is that it does not contain heavy metals, and the main recovery is Li, P, and Fe. The added value of recycled products is low. Need to develop a low-cost recovery route, there are mainly two recovery methods, fire method and wet method.

BYD announced a 20% increase in lithium battery product prices from November

Tuesday, October 26, 2021 9:03:39 PM America/Los_Angeles

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.
