磷酸鋰鐵是近來備受矚目的鋰電池正極材料,相對於傳統的鋰鈷電池,鋰鐵電池的特點為使用壽命長、高安全性與良好的耐熱性,能夠承受3~5 ℃甚至更高的充放電速率,而鋰鐵電池的原料並不是稀有金屬,可以顯著降低成本。因此,應用的範圍應將大於鋰鈷電池,可應用於太陽能LED路燈、車用電池、OLPC百元電腦以及電動代步車等。
超級電容器具有穩定的電壓,穩定全車電力系統,保護汽車電子元件及延長電池壽命的功能。它不需要破壞車線、不改變原來的設計,且安裝方便,直接銜接即可,可使汽車原裝電池成為高功率電池,提高瞬間高功率輸出,提高車輛的點火效果,提高引擎的燃燒效率,增加動力並減少燃料的消耗。
結合磷酸鋰鐵電池和超級電容器作為一種新的節能裝置。希望使用這種節能裝置,以降低汽車的油耗,提高引擎效率和減少空氣污染。測試後發現如果沒有加裝節能設備,汽車排放的廢氣中仍含有高達 2 vol.ppm碳氫化合物(例如苯),和0.07 vol.%的CO存在,但是,如果加裝節能設備,汽車排放廢氣中的成分碳氫化合物和一氧化碳組成已經很少,且也沒有發現含有苯的成分。在七人座2500cc車上安裝了節能裝置,其速度維持在50 km/hr至90 km/hr範圍內,節能裝置即可提高汽車引擎的燃油效率。
Lithium iron phosphate is the recent high-profile of the lithium battery cathode material, as opposed to conventional lithium-cobalt batteries, the lithium-iron battery characteristics are long life, high safety, good heat level, and can withstand 3 ~ 5℃, and even higher charge-discharge rate, while the use of lithium iron battery raw materials are not rare, you can significantly reduce costs. Super-capacitors have a stable voltage, stable and full-vehicle power systems, protection of vehicle electronics and extended battery life features. It need not destroy the car line.
Do not change the original design, easy to install, direct bridging car battery so that the original battery into a high-power batteries, to enhance an instant high-power output, improving vehicle ignition effect, increase engine combustion efficiency and increased power.
Combination of lithium iron phosphate battery and super-capacitors as an energy saving device. Hope to use this energy-saving device to reduce engine fuel consumption, improve engine exhaust and reducing air pollution. Researchers found that if no energy-saving equipment installed, the engine exhaust components are still up to 2 vol.ppm hydrocarbons (such as benzene), 0.07 vol.% CO exist, but, if installation of energy-saving equipment, engine exhaust components in the composition of hydrocarbons and CO have been very few ingredients and no benzene was detected. Energy-saving device can increase the fuel efficiency of car engines. In the seven-seater 2500cc car were installed an energy-saving device. The increased fuel efficiency about 20 % to 12 %, when the installation of energy efficient device and speed is at 50 km/hr to 90 km/hr range.
