Self-discharge measurement of lithium batteries: resting and dynamic measurement methods

Jun , 14 2023

The measurement methods of self-discharge of lithium-ion batteries are mainly divided into two categories: 1) static measurement method, which obtains the self-discharge rate by standing the battery for a long time; 2) Dynamic measurement method to realize the parameter identification of the battery in the dynamic process. Static measurement method At present, the mainstream self-discharge measure...

Why Choose a Lithium-Ion UPS Battery?

Jun , 21 2023

Although lithium-ion UPS systems have been around for decades, most people have been hesitant to choose this option because they were more expensive. With the onset of advanced battery technology, lithium-ion UPS systems have become much more attractive due to reduced pricing that rivals most standard, lead-acid battery UPS systems. UPS systems feature a state-of-the-art lithium iron phosphate (Li...

Effect of carbon black content on negative electrode performance of lead-acid battery

Aug , 04 2023

VRLA battery is not ideal in electric vehicles because of its short life under deep charge and discharge cycle conditions. In recent years, with the improvement of positive plate grid materials, the cycle life of batteries has been improved, and the main reason for the failure of VRLA batteries for electric vehicles is the sulfation of the negative electrode. To this end, there are more studies on...
