LFP Prismatic cells

Prismatic cells are constructed in a wound or flat plate configuration. Wound prismatic cells are generally constructed by wrapping layers around a bobbin or mandrel, similar to that of a cylindrical cell. In a flat plate cell, discrete layers are stacked side by side and pressed together or folded. Prismatic cells that are designed for automotive applications can have much larger capacities than cylindrical cells.

Here’s Why

Lithium ion batteries are inexpensive, readily available, and find more applications including vehicles. Additionally, lithium batteries last longer and easier to install than any other currently available alternatives including lead-acid batteries. Lithium iron phosphate battery (LiFePO4 battery) is a new promising technology. While lithium iron phosphate batteries have both advantages and disadvantages, there are several features that make this solution a great fit for different applications.

Stable Chemistry among Li-ion

Cell density is a description of how much power is stored in a given space. A higher density means battery can run longer. This means LiFePO4 batteries will have to be slightly larger to hold the same amount of energy as a regular lithium ion battery. A lower cell density makes the batteries less volatile. LiFePO4 batteries are highly unlikely to overheat or worse - catch fire, even if they are overcharged. The advantage of stability is particularly pronounced in higher temperature environments and situations where a high voltage is needed.

Longevity

The chemistry makeup of the electrolyte used in LiFePO4 batteries allows it to last significantly longer than standard lithium ion variety. The longer shelf life is particularly helpful in solar situations, where setups are designed to back-up power at home or business for years. LiFePO4 batteries are also practically maintenance-free & installed in out-of-the way spaces.

Environmental Advantages

Many customers are looking to make less of an impact on the environment. Not all batteries are typically eco-friendly. Luckily, LiFePO4 batteries offer some mitigating factors that make them more environmentally friendly than any other batteries. While basic lithium ion batteries contain hazardous materials, LiFePO4 batteries are not considered toxic as they contain common & readily available materials like iron, graphite and copper. This makes them easier to recycle – in fact, some LiFePO4 batteries are already made from recycled materials. A longer shelf life means LiFePO4 batteries in solar plus storage installations need not be replaced as often, using even less energy to process materials.
