Global lithium-ion battery market trend 2023-2028 The common problems in the use and maintenance of lithium batteries by Newsen-mcafee

Argentina's Rosario Grain Exchange recently reported that wheat lithium-ion battery are expected to continue to be influenced by international situations.

1. Basic concepts of lithium-ion battery:

The lithium-ion battery has a nominal voltage of 3.7V (3.6V) and a charge cut-off voltage of 4.2V (4.1V, which has different designs according to the brand of the battery). (The specification for lithium-ion batteries is: lithium-ion secondary batteries

2. Requirements for charging lithium-ion battery (GB/T182872000 specification)

First of all, constant current charging, that is, the current is constant, and the battery voltage gradually increases with the charging process. When the battery terminal voltage reaches 4.2V (4.1V), the constant current charging is changed to constant voltage charging; the voltage is constant, and the current is based on the battery. The saturation level gradually decreases as the charging process continues, and when it decreases to 0.01C, the charging is considered to be terminated. (C is a way of expressing the battery's nominal capacity against the current. For example, if the battery has a capacity of 1000mAh, 1C is the charging current of 1000mA. Note that it is me instead of mAh, and 0.01C is 10mA.) Of course, the standard representation is 0.01 C5A, simplified here.

3. Why do you think 0.01C is the end of charging?

This is stipulated by the national standard GB/T18287-2000, and it is also discussed. In the past, everyone generally ended with 20mA. The industry standard YD/T998-1999 of the Ministry of Posts and Telecommunications also stipulates that no matter how large the battery capacity is, the stop current is 20mA. The 0.01C specified by the national standard helps charge more fully, which is beneficial for the manufacturer to pass the appraisal. In addition, the national standard stipulates that the charging time should not exceed 8 hours; that is to say, even if it has not reached 0.01C, the charging is considered to be over after 8 hours. (Batteries with good quality should reach 0.01C within 8 hours, for batteries with poor quality, it is meaningless to wait).

4. How to distinguish whether the battery is 4.1V or 4.2V?

Consumers are indistinguishable; it depends on the product specification of the cell manufacturer. Some brands of batteries are 4.1V and 4.2V universal, such as A&TB (Toshiba); domestic manufacturers are 4.2V, but there are exceptions, such as Tianjin Lishen is 4.1V (but it is currently 4.2V).

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the lithium-ion battery and the market of the lithium-ion battery.
