This article mainly introduces the measurement methods of voltage, charging current, and discharge current of lithium batteries. It is simple and easy to learn, and can be done with just a multimeter. Let's take a look together.1> How to measure the voltage of a battery:The voltage of the bat...

As an energy storage device comparable to batteries, supercapacitors have the most significant characteristics of high power density, large capacity, fast charging, high current discharge, multiple charging and discharging times (500000 times), safety, and environmental protection. The disadvantages...

Parallel connection of batteries requires the same capacity and voltage, and it is not allowed to connect new and old batteries in parallel. After parallel connection, the maximum output current that the battery can provide will double, but the current generated by the motor during use will not incr...

In general, there are four types of battery leakage, and the most common one is poor sealing between the top cover and bottom groove, which leads to cracking; And there are also cases of safety valve leakage and wiring leakage, but the probability is not high; The last type is leakage from other par...

Water based binders SBR, CMC Na:1) Introduction: SBR is the most widely used water-based adhesive. SBR stands for styrene butadiene rubber, which is highly soluble in water and polar solvents. It has high bonding strength, good mechanical stability, and operability. When used as an adhesive in the b...

Which is better, lithium iron phosphate battery or ternary lithium battery? What is the main difference between lithium iron phosphate batteries and ternary batteries? There are two common materials in the lithium battery market now, ternary materials and lithium iron phosphate. How do we make a cho...

The principle of lithium battery repair method 2: Low temperature can cause changes in the electrolyte inside the lithium battery, promoting chemical reactions in the newly frozen battery. The use of lithium batteries is actually a process of charging and discharging. During this period, the negativ...

Battery energy: refers to the electrical energy output from external work under certain discharge conditions;Specific energy: The energy provided by a battery per unit weight or volume, called weight specific energy or volume specific energyThe weight specific energy and volume specific energy of li...

The full name of ternary lithium battery is positive electrode material. It is a lithium-ion secondary battery that uses ternary polymers such as nickel cobalt manganese lithium or nickel cobalt aluminum lithium. Ternary refers to a polymer containing three metal elements: nickel (Ni), cobalt (Co),...
