Lithium iron phosphate performance

Yunnan Yuxi Huilong technology has lithium iron phosphate battery Huilong lithium iron phosphate battery

The lithium iron phosphate positive material produced by Yunnan Huilong is based on its own unique process technology of high-performance lithium spinel manganate, special geographical environment and the rich in manganese, iron, phosphorus and other natural materials of the metal kingdom, mineral resources, olivine lithium iron phosphate (LiFePO4) positive. quality material after years of careful research and development. We have created an environmentally friendly material that is the least expensive and offersbetter overall performance than materials from other manufacturers. Its advantages are high gram capacity, high powder conductivity, good cycle stability and low price, it is used to prepare pole pieces; adhesives. The quantity is small (3~4%), the lithium iron phosphate content can reach 94%, and the processing performance is good. High capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, capable of large current charge and discharge, stable electrochemical performance, safe to use (will not cause burn or damage due to improper operation such as overcharge, overdischarge, short circuit, explosion etc.), wide operating temperature range, non-toxic or less toxic, and no pollution to the environment. Lithium iron phosphate batteries using LiFePO4 as positive electrodemeet these performance requirements, especially in terms of high discharge rate (5-20°C discharge), stable discharge voltage, safety (no combustion, no explosion) and service life ( number of cycles), no pollution to the environment, it is the best, and it is currently the best positive material for high current power batteries.

Under 100% DOD conditions, it can be charged and discharged more than 2,000 times; (Reason: Lithium iron phosphate lattice has good stability and lithium ion intercalation. Input and output have little effect on the crystal lattice, making it have good reversibility. The disadvantage is that the electrode has poor ionic conductivity and is not suitable for charging and discharging large currents, which hinders its application Solution: Coat the electrode surface with conductive materials and dope to modify. the electrode. )

The lifespan of lithium iron phosphate batteries is closely related to its operating temperature. If the operating temperature is too low or too high, it will cause great hidden dangers in its charging, discharging and discharging processes. 'use. Especially when used in electric vehicles in northern China, lithium iron phosphate batteries cannot provide normal power or the power supply is too low in autumn and winter, and the temperature of the working environment must be adjusted to maintain its performance. At present, domestic solutions to the constant temperature working environment of lithium iron phosphate batteries need to consider space constraints. The most common solution is to use airgel felt as an insulating layer. Lithium batteries with lithium iron phosphate cathode material can be charoperated at a high rate and can be fully charged in just 1 hour.
