With the increase of market demand, lithium battery industry is expanding. There are many lithium battery brands on the market, which are difficult to distinguish.
In general, the evaluation indicators for any lithium battery product mainly include:
1. Energy density;
2. Rate performance (i.e. discharge performance under different currents);
3. Safety performance;
4. Cycle life;
The difference in safety between lithium polymer batteries and lithium-ion batteries is that when both batteries are heated to a certain extent, lithium-ion batteries will explode, while lithium polymer batteries have only chemical properties. Volatile, flammable at most, but never explosive.
With the increase of market demand, the lithium battery industry continues to expand. There are many lithium battery brands on the market, and it is hard to tell whether they are good or bad.
On August 1, the first national mandatory standard GB 31241-2014 safety requirements for lithium ion batteries and battery packs for portable electronic products in the lithium battery industry was officially implemented. This means that from August 1st, 2015, the state will conduct irregular sampling inspection.
I am Xiaobei from BPI. Today, Xiaobei will take you into the BPI battery and explore the lithium battery pack. First of all, what is packaging? What is a lithium battery pack?
BPI is a battery manufacturer integrating production and sales of lithium battery, nickel battery, PACK battery and outdoor energy storage. low self-discharge cell, ultra low self-discharge cell, nickel metal hydride battery pack, lithium battery pack, outdoor power supply and other battery production and processing
The chemical characteristics of lithium metal are very active, which makes the processing, preservation and use of lithium metal very high requirements for the environment. With the development of science and technology, lithium battery has
