Contrast is really good ability - Nice resistance lithium iron 7 battery comparison test
Nice lithium iron battery has been used for a period of time, I feel pretty good, but to say where the specific good, still need to compare and data to speak, the following and our two most commonly used batteries: ordinary alkaline batteries and Ni-MH rechargeable battery to a comparative evaluation. Comparison battery: GP alkaline battery; enelong 900mAh nickel-metal hydride battery. A. Nice lithium iron battery technology Compared to our common alkaline and nickel-metal hydride batteries, lithium-iron battery technology has only begun commercial use in recent years. Everyone is still unfamiliar with this new technology. :"Different from common alkaline and carbon batteries, the cathode material is ferrous disulfide (FeS2), and the negative electrode is metallic lithium (Li). The typical capacity is 3000mAh and the minimum capacity is 2900mAh. Compared with the traditional alkaline battery, it has the following: Advantages: Compatible with 1.5V alkaline batteries, carbon battery electrical appliances; suitable for large current discharge; sufficient power, its actual discharge capacity exceeds the commercial primary battery on the market; temperature range is much wider than other primary batteries, Excellent low temperature performance, official operating temperature reference -40°C to 60°C; small size, light weight, anti-leakage liquid; low self-discharge, can be stored up to 10 years; no harmful materials to the environment, no mercury, no chromium from raw materials Real zero pollution." Second, the weight Lightweight lithium iron battery is a major feature, the following with the Logitech K380 to show you the next. Ordinary alkaline battery 409.0g Ni-MH battery 410.0g Lithium-iron battery 400.0g It can be seen that the lithium lithium iron battery is lighter than 10g and has a single section of 5g. Compared with the 7th battery, the volume weight is still quite considerable. Third, the new battery open circuit voltage GP's new battery open circuit voltage is 1.598v Ni-MH is 1.303v The new battery open circuit voltage of Nice lithium iron battery is 1.838v It can be seen that the open circuit voltage of lithium-iron TVs is higher than that of ordinary batteries, but compared to other types of lithium batteries, it belongs to low-voltage lithium batteries. Do not know how the load situation, the following we will test the discharge situation Fourth, the discharge curve Test Instrument: Smart Eye Charger, Test Mode is Discharge Mode Initial load voltage: GP: 1.400v enelong: 1.250v Nice: 1.490v Discharge current is close to 550mA 1 minute data: GP: 1.365v enelong: 1.243v Nice: 1.469v 2 minutes data: GP: 1.347v enelong: 1.242v Nice: 1.475v 5 minutes data: GP: 1.330v enelong: 1.243v Nice: 1.487v 10 minutes of data: GP: 1.306v enelong: 1.250v Nice: 1.524v 15 minutes of data GP: 1.284v enelong: 1.252v Nice: 1.638v 20-minute data: GP: 1.253v enelong: 1.250v Nice: 1.633v 25 minutes data: GP: 1.240v enelong: 1.248v Nice: 1.628v 30-minute data: GP: 1.228v enelong: 1.243v Nice: 1.617v From the discharge curve, it can be seen that the attenuation of the alkaline battery is the most obvious and relatively linear, while the nickel-metal hydride discharge is relatively stable, while the Nice lithium iron battery maintains a relatively high voltage, even after a The process of slowly recovering the voltage is relatively rare. Fifth, temperature After a long time of discharge, the temperature of the battery is also a more important parameter. Hereafter, the temperature after discharge for 30 minutes is measured. After half an hour of discharge, the temperature of the charger is 42.1° GP temperature is 45.6° Enelong is 42.3° Nice is 43.5° Although this temperature measurement is relatively affected by the charger, it can still be seen that the temperature rise of the alkaline battery is still the largest, followed by Nice, Ni-MH is the lowest. Conclusion Nice lithium-iron battery has small size, light weight, anti-leakage; low self-discharge, environmental pollution and other characteristics of zero, although several indicators tested today can not fully examine the performance of lithium iron batteries, but also can watch the panther, Nice Lithium-iron batteries are indeed light weight, high no-load voltage, high and stable load discharge voltage, and long-term discharge heating is not obvious, it is indeed quite good. The non-polluting environment-friendly features allow it to be more developable and optimistic about the future of Nice-resistant lithium-iron batteries. . .
