1. Custom Lithium Polymer Battery

Lithium Polymer batteries are different from the lithium ion batteries in their construction alone but similar in their chemistry. Li polymer has various chemistries at which it is made with the Li cobalt being the most used. Conventional Li ion cells differ in construction which allows for lower cost, flexible packaging options and safer operation with custom lithium battery packs being as slim as a credit card (yes, that slim). All these features make the custom lithium polymer battery packs and assemblies a better choice for various applications.

To get a good custom lithium polymer battery and battery pack assembly, kindly contacts a reputable lithium polymer battery manufacturer.


2. LiFeMgPO4 Battery

Lithium Iron Magnesium Phosphate (LiFeMgPO4) is known to have a high higher energy density which makes the LiFeMgPO4 battery useful for several applications. It is considered to be less toxic, safer, producing more energy and having a longer life cycle. There are other advantages such as it is lightweight, has higher energy density, internal cell balancing and requires less maintenance.

LiFeMgPO4, when compared to Nickel Cadmium and Lead Acid, offers higher energy density; it is also safer than products of lithium oxide or mixed oxide batteries. Short circuited or punctured lithium oxides cells are known for causing heating, releasing oxygen and have the potential for a thermal runaway. The life cycle of LiFeMgPO4 is much longer having 2800 cycles at 80% discharge depth.

Valence Technology, a lifepo4 battery manufacturer, has an ISO 9000 certification which is usually given to companies that have the highest quality management practices. SPC methods used for manufacturing are deployed by Valence Energy Tech (VET) and work is being done for accreditation.

Valence Cathode Materials are made using a versatile and unique preparative method known as Carbothermal Reduction (CTR). This is a process for developing lithium iron magnesium phosphate cathode powder in a cost effective, very efficient, scalable and stable way.

The lithium iron magnesium phosphate powder is made high quality and longer-lasting by the CTR method, with enhanced performance, more sustained conductivity and a better cathode material which manufactured into cells more easily.


Pros and Cons of Lithium Iron Phosphate Batteries

Usually, the rechargeable lithium iron packs utilize a lithium ion chemistry method which has similar advantages and disadvantages of other chemistries lithium ion battery.

One merit of the lithium iron phosphate battery pack is that it provides sufficient thermal and chemical stability, better safety characteristics than lithium ion batteries which use other cathode materials. In the case of mishandling when charging or discharging, the rechargeable lithium iron phosphate battery is known to be incombustible. This makes it able to handle higher temperature without any damage occurring. The advantage of this battery over others includes its higher rate discharge capability and the longer life cycle it possesses.

As the lithium iron phosphate battery has merits, it also has its shortfalls, too. One of them is the energy density being lower than that of lithium cobalt oxide cell batteries. This has led to battery manufacturers all over the world working to find newer ways for maximizing energy and storage performance of the chemistry working principles of all batteries while reducing their weight and size simultaneously.

Just like lithium ion cells, lithium iron batteries are specially formulated for providing better energy or power characteristics which depend on if there is a long run time or it needs a high discharge rate.
