What factors are affecting the side reactions of lithium deposition?

Sep , 17 2021

When charging lithium ion battery, Lithium precipitation not only reduces the performance of the battery and greatly shortens the cycle life, but also limits the fast charging capacity of the battery, and may cause disastrous consequences such as combustion and explosion. In a series of articles we will discuss about the problems from the macro scale of lithium-ion battery, working conditions, gra...

Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-2

Nov , 01 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...
