Lithium batteries: The positive electrode plate is made of ductile carbon, and the negative electrode is made of lithium-ion compounds. Currently, there are two types: lithium cobalt oxide and lithium iron phosphate. There are roughly two types of structures: one is a wound type, and the other is a...

What are the hazards of lithium-ion batteries? How much harm does battery pollution bring? In today's society, the demand for batteries is constantly increasing, resulting in a significant increase in battery production. Some uncivilized people are accustomed to littering discarded old batteries...

In the process of daily use of electric vehicles, many friends have encountered situations where the electric vehicle battery suddenly cannot be charged, or has been charged for a long time but has not been fully charged. At this time, most people will think that the battery is not working.Actually,...

There is a rumor recently that lithium batteries that are about to be scrapped can be put into the refrigerator for three days to freeze, and then taken out to revive and restore their use. Is it really that divine?The batteries mentioned in this article starting from the next paragraph all refer to...

1. Lithium ion batteries and lithium polymer batteries can be distinguished on the packaging label of the battery. Lithium ion batteries are usually labeled with the word Li ion, while lithium polymer batteries are usually labeled with the word Li Polymer, as shown in the following figure. Meanwhile...

If used in a new car, the service life is generally about 3-4 years, and after a replacement, the service life is about 2 years.Maintenance free batteriesdefinition:Sealed maintenance free batteries adopt the latest fully sealed structure and modern production technology designed in the 1990s. Make...

When it comes to lithium batteries, we all know that some friends ask what kind of battery is commonly used for electric vehicle batteries. In addition, some people want to ask whether electric vehicle batteries are better than lithium batteries or lead-acid batteries. What's going on? In fact,...

Many electric vehicle users have this question, which is how much electricity does it take to fully charge an electric vehicle? What is the power consumption per kilometer? As a mechanic, today I will give you a detailed answer to this question.At present, most electric vehicles are 48V, 60V, and 72...

Introduction to wiring circuits and methods for lithium battery protection boards. As a safety protection device for lithium-ion batteries, the protection board should not only work reliably within the normal operating current range of the equipment, but also act quickly in case of accidental short...

Pulse charger is a type of dynamic charging that changes the charging current and voltage with the capacity and internal resistance of the battery itself. It achieves a balance between charging and discharging under this dynamic condition, and can also remove sulfates that appear in the battery afte...
