Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-4

Nov , 03 2021

During the long-cycle cycle, the reversible capacity of the lithium-ion battery will continue to decrease due to the reduction of active materials, the precipitation of metal lithium, the continuous consumption of electrolyte, the increase of internal resistance and thermal runaway. Among them, the lithium evolution phenomenon of the graphite negative electrode is the most important cause of batte...

Three things the energy storage industry should know about end of battery life

Nov , 12 2021

In the latest update of Circular Energy Storage’s data on the lithium-ion battery end-of-life market we conclude that over 1.2 million tons of waste batteries will be recycled in 2030. Although it sounds like a massive number, the recycling industry is in fact well prepared and will most probably fight for the volumes. This is good news for the energy storage industry, as it is for all other busin...

What is the right duration of Phase 2 of a charging cycle?

Nov , 27 2021

The duration of Phase 1 is determined by the battery’s depth of discharge, the ratio of charger ampacity to battery capacity, and whether there are parasitic DC loads connected to the system. Although the duration of Phase 1 does vary, we are not concerned with this variation since, once the battery capacity, charger output, and DC loads are installed, we have no means to change the duration of Ph...

Determining the lifespan of a battery

Dec , 31 2021

The lifespan of a battery will vary considerably with how it is used, how it is maintained and charged, the temperature and other factors. Also the type of battery will determine its lifespan. 12 Volt Gel or AGM batteries If kept in a charged state when unused, the common lifespan of a 12-volt Gel or AGM battery is up to six years. After five or six years of float voltage at an average ambient tem...

What is Thermal runaway and what is its impact on cell chemistry?

Jan , 06 2022

One of the main causes of danger for lithium-ion cells is related to the phenomenon of thermal runaway. This is a healing reaction of the battery in use, caused by the nature of the materials used in the chemistry of the battery. Thermal runaway is mainly caused by the solicitation of batteries under specific conditions, such as overload under adverse climatic conditions. The result of a thermal r...

4 Ways Lithium Batteries Power Up Solar

Jan , 17 2022

Investing in solar is smart; pairing solar with a lithium battery storage unit is even smarter. While lithium batteries tend to be a higher initial investment than lead acid batteries, their superior performance and longevity makes them an ideal choice for off-grid and grid-tie applications. When selecting a battery to complement your solar system, understanding the advantages that lithium batteri...

What are the major factors needs to be considered in vehicle application Lithium battery?

Feb , 12 2022

Lithium batteries are lightweight and provide higher energy density than lead-acid or nickel–metal hydride (NiMH) batteries, creating a demand for them in electric vehicles (EV), energy storage, and consumer electronics. Compared to NiMH batteries, lithium batteries have a 50 percent greater capacity in watt-hours per kilogram (w-h/kg). The EV industry is demanding higher-efficiency batt...

Effect of electrolyte on SEI film

Sep , 05 2022

The electrolyte is the main source of the reduction reaction reactants for the formation of the SEI film , and both the electrolyte solvent and the lithium salt will affect the composition of the SEI film. When the main components of the electrolyte are basically fixed, the performance of the SEI membrane can only be improved by other means. The researchers found that the formation of the SEI film...

Failure causes of lithium battery- Failure during shelving

Oct , 08 2022

In the service life of the power battery, most of the time is in a state of shelving. Generally, after a long period of shelving, the performance of the battery will decline, generally showing an increase in internal resistance, a decrease in voltage, and a decrease in discharge capacity. There are many factors that cause the degradation of battery performance, among which temperature, state of ch...

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...
