Damage of lithium battery caused by overcharge and discharge

Apr , 24 2023

The cathode materials of lithium-ion batteries are usually composed of active compounds of lithium, while the negative electrodes are carbon with special molecular structure. The main components of the common cathode materials are licoo2/LiFePO4, etc. When charging, the potential added to the battery poles forces the positive compounds to release lithium ions and embed the anode molecules into the...

Analysis of BMS (Battery Management System) Protection Mechanism and Working Principle

May , 06 2023

I. BMS function First, we'll detail its four main functions. (1) Perception and measurement Measurement is the perception of the state of the battery This is the basic function of BMS, including the measurement and calculation of some index parameters, including voltage, current, temperature, power, SOC (state of charge), SOH (state of health), SOP (state of power), SOE (state of 能源). SOC can be c...

Factors to consider while buying UPS

May , 09 2023

A UPS or uninterruptible power supply acts as a power-backup device for all the connected appliances in case the main supply fails. It employs a rectifier-battery-inverter setup which stores energy when the supply is available and feeds it during power cuts and blackouts. A UPS protects the connected gadgets from switching-off suddenly, thereby preventing data or functional loss of appliances. Wha...

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...

Preparation of lead-reduced graphene oxide nanocomposites and their applications

Jun , 14 2023

The shortcomings of lead-acid batteries are: low energy density and short cycle life. Lead sulfate formed by the negative plate of the lead-acid battery during the discharge process, after the battery is placed, the small particles of lead sulfate will be converted into large particles of lead sulfate, and the large particles of lead sulfate will not be converted into lead during the charging proc...

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...
