<p><a href="https://www.ufo-battery.com/lifepo4-battery-pack" rel="noopener noreferrer" target="_blank">Lifepo4 lithium battery</a> refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickelate, ternary materials, and lithium iron phosphate. Among them, lithium cobalt oxide is currently the cathode material used in most lithium-ion batteries. In terms of material principle, lithium iron phosphate is also an intercalation and deintercalation process, which is exactly the same as lithium cobaltate and lithium manganate.</p><p><br></p><p>A brief introduction of lithium iron phosphate batteries</p><p>Lithium iron phosphate batteries are lithium-ion secondary batteries. One of the main uses is for power batteries, which have great advantages over NI-MH and Ni-Cd batteries.</p><p>The charging and discharging efficiency of lithium iron phosphate batteries is relatively high, and the charging and discharging efficiency can reach more than 90% in the case of rate discharge, while the lead-acid battery is about 80%.</p><p><br></p><p>7 advantages of lithium iron phosphate batteries</p><p>1. Improvement of safety performance</p><p>The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat like lithium cobalt oxide or form strong oxidizing substances, so it has good safety. A report pointed out that in the actual operation of acupuncture or short-circuit experiments, a small part of the samples were found to burn, but no explosion occurred. In the overcharge experiment, a high voltage charge that was several times higher than the self-discharge voltage was used, and it was still found Explosion phenomenon. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries.</p><p><br></p><p>2. Lifespan improvement</p><p>lifepo4 lithium battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material.</p><p>The cycle life of a long-life lead-acid battery is about 300 times, and the highest is 500 times. The lithium iron phosphate power battery has a cycle life of more than 2000 times, and the standard charge (5 hour rate) use can reach 2000 times. Lead-acid batteries of the same quality are "new half a year, half a year old, and half a year for maintenance", which can take up to 1 to 1.5 years, while lithium iron phosphate batteries used under the same conditions have a theoretical life of 7 to 8 years. Considering comprehensively, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries. High-current discharge can quickly charge and discharge high current 2C. With a dedicated charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, but lead-acid batteries have no such performance.</p><p><br></p><p>3. Good high temperature performance</p><p>The peak value of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Wide operating temperature range (-20C--+75C), with high temperature resistance, lithium iron phosphate electric heating peaks can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.</p><p><br></p><p>4. Large capacity</p><p>It has a larger capacity than ordinary batteries (lead-acid, etc.). The monomer capacity is 5AH-1000AH.</p><p><br></p><p>5. No memory effect</p><p>Rechargeable batteries work under conditions that are often fully charged and not discharged, and their capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. Like Ni-MH and Ni-Cd batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be charged and used at any time without having to discharge it before charging.</p><p><br></p><p>6. Lightweight</p><p>The volume of the lifepo4 lithium battery of the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.</p><p><br></p><p>7. Environmental protection</p><p>The battery is generally considered to be free of any heavy metals and rare metals (the nickel-hydrogen battery requires rare metals), non-toxic (SGS certified), non-polluting, in line with European RoHS regulations, and is an absolute green battery certificate.</p><p><br></p>
