Why Golf Carts Should Choose Lifepo4 Batteries

Using lithium iron phosphate as the cathode material, lithium iron phosphate batteries are more stable than lead-acid batteries and less likely to overheat and catch fire. This is especially important in golf cart applications where the safety of the user and others on the course is paramount.

• lifepo4 battery excellent safety performance advantages

• High safety performance: The PO bond in the LiFePO4 crystal structure is stable and not easy to decompose. Even under high temperature or overcharge conditions, there will be no structural collapse or the production of highly oxidizing substances like lithium cobalt oxide batteries. The decomposition temperature of LiFePO4 is approximately 600°C, which contributes to its excellent safety performance.

• Long Life: Lead-acid batteries typically have a cycle life of about 300 cycles, with a maximum of about 500 cycles. In comparison, LiFePO4 batteries can achieve a cycle life of more than 5 cycles when using standard charging (2000C, 0.2 hours). Under the same conditions, the theoretical life of lithium iron phosphate batteries is 4 to 7 years, while the life of lead-acid batteries of the same weight usually does not exceed 8 to 1 year. Taking all factors into consideration, the cost performance of lithium iron phosphate batteries is theoretically more than four times that of lead-acid batteries.

• High temperature resistance: Lithium iron phosphate batteries have a wide operating temperature range (-20°C to +75°C) and exhibit excellent high temperature resistance. The thermal peak of LiFePO4 battery can reach 350℃ to 500℃, while LiMn2O4 battery and LiCoO2 battery only reach about 200℃.

• Large capacity: Compared with ordinary batteries such as lead-acid, LiFePO4 batteries have larger capacity. The energy density of lead-acid batteries is about 40 Wh/kg, while the energy density of mainstream lithium iron phosphate batteries in the market reaches 4 Wh/kg or higher.

• No memory effect: Like most lithium-ion batteries, LiFePO4 batteries have no memory effect. They can be charged and used in any state of charge without having to be fully discharged first. If a rechargeable battery is used frequently without being fully discharged, its capacity will usually decrease, which is called the memory effect.

• Lightweight: A lithium iron phosphate battery with the same capacity is two-thirds the volume and one-third the weight of a lead-acid battery. However, their energy density is several times higher than that of lead-acid batteries.

• Environmentally friendly: LiFePO4 batteries are generally considered to be free of heavy and rare metals, non-toxic (certified by SGS), non-polluting, and compliant with European RoHS regulations. They are considered green and environmentally friendly batteries. The environmental protection of lithium batteries is one of the key reasons why they are favored by the industry.

• LiFePO4 batteries also have their disadvantages:

• Threat of iron element: During the sintering process of preparing LiFePO4, iron oxide may be reduced to elemental iron in a high-temperature reducing atmosphere. Elemental iron can cause micro-short circuits in batteries and is the most undesirable substance in battery systems. This is also the main reason why Japan does not use this material as anode material for power lithium-ion batteries.
