LITHIUM IRON PHOSPHATE 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. Additionally, lithium batteries last longer and easier to install than any other currently available alternatives including lead-acid batteries.
STABLE CHEMISTRY AMONG LI-ION
Cell density is a description of how much power is stored in a given space. A higher density means the 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.
The chemistry of the electrolyte used in LiFePO4 batteries allows it to last significantly longer than the 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.
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.
LFP CYLINDRICAL CELLS
Cylindrical cells are a popular and less expensive option for electric vehicles, largely because their construction was born out of the consumer battery space. It probably offers the greatest ease in terms of capability. However, the disadvantage is that it requires a lot more interconnects and complexity in terms of designs.
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.
LFP POUCH CELLS
Pouch cells are fundamentally prismatic cells with flexible polymer coated aluminum packaging instead of a metal can. The individual layers are stacked or folded, packed under vacuum and held together by the pouch. Most of the pouch designs use a gel electrolyte technology, while typical lithium ion cells used by manufacturers use liquid. A pouch's gel electrolyte has higher resistance but doesn't have the risk of spilling which a liquid electrolyte does.
