The causes of short circuits in lithium-ion batteries (1) The positive electrode material is impure or left in the air for too long, resulting in incomplete drying; Failure to remove transition metal impurities from the positive electrode slurry can lead to penetration of th...

1. Do not contact the positive and negative poles of lithium-ion batteries with metal objects during use, and keep them away from metal objects and places with high temperatures to avoid short circuits in lithium-ion batteries. 2. When not in use for a long time, lithium-ion...

1. The numbers 18650 in the 18650 lithium-ion battery represent the external dimensions: 18 refers to the battery diameter of 18.0mm, 65 refers to the battery height of 65.0mm, and 0 refers to the cylindrical battery. Common 18650 batteries are divided into lithium-ion batteries and lithium ir...

In addition, due to the low safety of lithium-ion batteries and their sensitivity to temperature in the environment, we should pay more attention to the temperature of the environment when using lithium-ion batteries. 40 to 60 degrees Celsius is the optimal temperature for lithium-ion batteries, and...

The lithium-ion battery, also known as lithium-ion battery, commonly mentioned in our daily life, is a type of battery developed by utilizing the active chemical properties of lithium metal. The essence of the charging and discharging process of this battery is actually achieved through the ga...

1. Over discharge protection: When the polymer lithium-ion battery is about to run out of battery power and the voltage reaches a required minimum value, the protection board will close and cannot discharge anymore. As a result, the product will automatically shut down, forming a type of over...

Technical monitoring of forklift and battery status to improve the management level of lithium-ion battery forklifts. Firstly, the consistency of the battery. Power lithium battery products should achieve safety, high energy density, and good high and low...

Advantages of lithium-ion battery forklifts: 1. Reduce logistics costs Long lifespan: Three times longer than traditional lead-acid batteries. Cost saving: Save over 40% electricity and reduce management costs. Maintenance fre...

(3) Vacuum heat treatment method The vacuum heat treatment method developed by German company Alte is even cheaper, but this first requires sorting out nickel cadmium batteries from waste batteries. The waste batteries are heated in vacuum, and the mercury quickly evaporates...

(1) Heat treatment There are two factories in Switzerland that specialize in processing and utilizing old batteries. The method adopted by Bartleck Company is to grind the old batteries and then send them to the furnace for heating. At this time, the emitted mercury can be e...
