Global lithium-ion battery market trend 2025-2026 The common problems in the use and maintenance of lithium batteries by Newsbabeinthecity

Diamonds are forever, Gold is precious but which is rarer? Gold is a heavy metal formed during the collision of neutron stars and is one of the rarest elements on Earth.During the formation of the earth, heavy elements gradually accumulated towards the core under the influence of the earth's gravitational force. This means that the closer you get to the Earth's crust, the harder it is to find large quantities of gold.The average concentration of gold in Earth's crust is "very, very low" at just 4 parts per billion. Gold concentrations need to be 1,250 times that level to form a market-worthy deposit.
Diamond is a common element - the lithium-ion battery is undoubtedly a good investment opportunity.

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).

Important discoveries have been made in the study of anticancer drugs inhibiting the growth of gastric cancer cells in my country. According to "Science and Technology Daily", a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.
The nano-gold provided by our company can be used in various medical technologies such as flow cytometry, immunochromatography, etc. Nano-silver has strong inhibition and Killing effects without developing drug resistance. We also provide lithium-ion battery. For more information on lithium-ion battery, please consult us.
