Safety of Lithium-Ion batteries

Aug , 08 2022

Lithium-Ion refers to a family of Lithium-based battery technology. This family includes several sub-families or technologies, such as: ·LCO: Lithium Cobalt Oxide ·NCA: Nickel Cobalt Aluminium ·NMC: Nickel Manganese Cobalt ·LiFePO4 or LFP: Lithium Iron Phosphate ·LTO: Lithium Titanate Oxide, etc… Often, we can hear that a product is equipped with “Lithium-Ion” batteries; this does not really have ...

Fourier Analysis of input current of Single phase controlled bridge rectifier

Aug , 29 2022

While the use of uncontrolled rectifier circuits remains prominent, for some applications, more control and efficiency is necessary. This can be accomplished through the use of a controlled rectifier circuit in which thyristors connected in a full-bridge configuration adjust the average voltage. Each thyristor has a gate that controls when it turns on. With control circuitry these devices can be o...

SEI film formation mechanism

Sep , 05 2022

During the formation of the SEI film, various reduction reactions are carried out by the electrolyte solvent, lithium salt, additives, and trace air impurities. This series of reactions is not only affected by the inherent properties of substances such as reduction potential, reduction activation energy, and exchange current density, but also by other factors such as temperature, electrolyte salt ...

Influence of SEI film on the performance of Li-ion battery

Sep , 05 2022

After extensive research, it has been found that the properties of SEI films greatly affect the performance of Li-ion batteries. During the formation process, the amount of the SEI film formed represents the amount of lithium in the consumed lithium-ion battery, which directly determines the capacity of the lithium- ion battery. Therefore, in the process of forming the SEI film, the less lithium i...

Advantages and disadvantages of lithium iron phosphate battery and ternary lithium battery

Sep , 05 2022

1. Energy density: The energy density of ternary lithium is about 1.7 times that of lithium iron phosphate, so the volume and weight of ternary lithium batteries will be smaller than those of lithium iron phosphate batteries, and the car load will be smaller. 2. Safety performance: lithium iron phosphate battery will perform better in acupuncture test, and in high temperature environment, the stab...

How a UPS system works with a Generator

Sep , 19 2022

As weather extremes and storms increase, power outages are likely to continue to rise. According to the U.S. Energy Information Administration, U.S. customers experienced an average of nearly six hours of power interruptions in 2018. If you have invested in a generator, you’ve prepared for when a storm hits, right? Almost. Even with a generator, you still need a battery backup, also known as an Un...

Key Factors in Choosing the Right UPS

Sep , 26 2022

You rely on your UPS system for backup if your power goes out, right? But does your UPS have your back? That is, will it provide a bridge of power long enough for what you need? At the very least you will want to save your data and perform a safe shutdown. Your UPS backup battery will only provide power for a set amount of time, known as runtime. In this article, we will provide a step-by-step app...

Failure causes of lithium battery- Failure during recycling

Oct , 08 2022

The battery is generally exothermic during use, so the effect of temperature is very important. In addition, road conditions, usage, ambient temperature, etc. will have different effects. The capacity loss of LiFePO4 power batteries during cycling is generally considered to be caused by the loss of active lithium ions. The research shows that the aging of LiFePO4 power battery during cycling is ma...

Failure causes of lithium battery- Failure during charging and discharging

Oct , 08 2022

The battery is often overcharged in the process of use. Relatively speaking, the overdischarge situation is less. The heat released during the overcharge or overdischarge process is easy to accumulate inside the battery, which will further increase the battery temperature. , affecting the service life of the battery and increasing the possibility of the battery catching fire or exploding. Even und...
