However, low efficiency and Depth of discharge are the main shortcomings of lead-acid battery. With the emergence of LiFePO4 battery, it is becoming popular to be applied for energy storage system because of the benefits of high efficiency and deep depth of discharge(DOD). Besides, the performance of lead acid batteries drops dramatically in both high and low temperatures, while lithium iron phosphate batteries have a good temperature resistance to operate in temperatures ranging from -20°C to 60°C. This characteristic makes LifePO4 batteries the ideal alternative for energy storage system in both the Arctic and Sub Saharan regions. They could be used in multiple kinds of energy storage system in every climate around the world.● Telecomunication Base Station Application The arrival of information age reflects the growing importance of communication base station to people because it is the infrastructure that make the network everywhere. If the base station stops operating, there would be no signal for mobile phone or network. Thus, the remote connection will be cut off, resulting in various inconvenience to the life in such Internet era. The importance of operation stability of the communication base station can be obviously seen.Due to the high reliability demand of communication base station, a complete communication power supply solution requires that the power supply system should be equipped with high-reliability and high-security batteries. The defects of lead-acid battery such as short life cycle, frequent maintenance and poor temperature resistance make it cannot perform as stable as lithium iron phosphate battery (LFP battery). Although the initial investment is higher, UFO LiFePO4 telecom battery is worthy for the good operation in the long run. LiFePO4 battery would be more favorable for telecommunication equipment. ● Solar Street Light ApplicationWhen it comes to the dark night, it is the street light that helps light up the world.

They also cycle up to 5,000 times, whereas lead acid batteries cycle only 300-500 times before failing. Moreover, lithium iron phosphate batteries can be charged at a constant current and constant voltage, which allows them to be recharged in a short time and return to work when they’re needed. These advantages make lithium iron phosphate batteries versatile for a variety of applications, such as golf cart, electric forklift, camper van, floor machine and other small electric vehicles.Read More>>
The Development of Lithium-ion Battery
Battery are commonly used today, it stores energy which can turn into electricity to supply power. Not only is the battery an extraordinary invention, but also it has a promising future. With the development of battery technology, lithium-ion battery comes into our daily life and has seen a growing increase in adoption. Now, lithium-ion technology are able to extend its potential on consumer electronics, energy storage system and even electrical vehicles.On October 9th, 2019, the 2019 Nobel Prize in Chemistry was awarded to three scientists, John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino, for their hard work in the development of lithium-ion batteries. Do you wonder the remarkable history behind the lithium-ion battery? Let’s start from the very beginning. Where does Lithium Come from? “Lithium is one of the three elements created in the initial condensation of matter from energy immediately following the Big Bang, the other two are hydrogen and helium.” Under standard situations, lithium is the lightest metal and lightest solid element. Why is this material called “lithium”?The name “Lithium” comes from the Greek words “lithos” which means stone. In 1817, Johan August Arfwedson detected the presence of a new element while analyzing petalite ore in the laboratory of the chemist Jöns Jakob Berzelius. Berzelius gave the alkaline material the name "lithion/lithina", to reflect its discovery in a solid mineral which is different from potassium that is found in plant ashes and also sodium that exists in animal blood. A Brief History of Lithium-ion BatteriesIn the 1970s, the first big oil crisis hit the world and the technology of lithium battery appeared at this critical moment. Stanley Whittingham, a chemist working at Exxon company started to develop new technology that could reduce world’s dependence on fossil fuel energy. He tried to use titanium disulfide for the cathode in a lithium battery. It is a 2V lithium-ion battery. However, because of safety failure of this kind of battery, the research of this lithium-titanium disulfide battery stopped. Stanley WhittinghamLithium-titanium Disulfide BatteryStanley Whittingham's Battery sourece: https://insideclimatenews.org/news/09102019/nobel-prize-chemistry-battery-whittingham-exxon-fossil-fuel-renewable-electric-vehiclesJohn B. Goodenough, who is an engineering professor at the University of Texas at Austin, had come up with a new idea that using a metal oxide instead of a metal sulfide for the cathode would be more potential. In 1980, he demonstrated that cobalt oxide with intercalated lithium ions can produce double energy than the lithium-titanium disulfide battery after a variety of research. This innovation was a breakthrough of lithium battery and make powerful batteries possible. John B. GoodenoughGoodenough's Battery source:https://www.houstonchronicle.com/news/education/article/UT-professor-John-B-Goodenough-awarded-Nobel-14503473.php#photo-18403111In 1985, Akira Yoshino of Meijo University in Nagoya, Japan, made another development. Rather than using reactive lithium for the anode, he attempted to use a material called the petroleum coke which lithium ions could be inserted as the anode. Lithium ions can be transported between the anode and cathode in this battery. The battery is light and durable and could be recharged hundreds of times before performance weaken. This revolutionary development dramatically increases the safety performance of battery and make the commercial lithium-ion battery feasible.

Why lithium battery is recommended in solar street light?
When it comes to the dark night, what helps light up your way while walking, driving or even commuting? It is the street light which is extremely handy source of light. And how does the street light work? It needs power. But what if the areas with a power outage or without much access to electricity? This is where solar street lights come into play. In order to make our world a greener world, environmentally friendly practices like utilizing clean and renewable energy is urgently needed to lower carbon footprint. With the rapid developments in photovoltaic and LED lighting technologies, solar street lights are increasingly popular in the market. The portability and eco-friendly nature of solar street lights make them an ideal alternative to ordinary street lights and perhaps a good choice for areas without electrical grids. These days it is common to see the solar street lights along the sides of roads.What is solar street light and how does it work?It is obvious that the solar street light work by utilizing the solar energy. The solar street lights depend on the principle of the photovoltaic cells or solar cells. So how do the solar street lights work? First, the photovoltaic cells are used as a mean for absorbing solar energy during the daylight. Then, the photovoltaic cells convert solar energy into usable electrical energy, which is stored in the battery. When the night falls, the electrical energy that stored in the battery is consumed to power the street light. During the day time the battery gets recharged and the process keeps on repeating every day. As long as the sun is up, this kind of solar street lights have a sustainable source of energy. What types of battery are used in solar street light? The battery is a key component of solar street lights system because it is where stores the electrical energy and powers the solar street light. Also, it is the major part of the cost of solar street lights. The solar street lights are working with different kinds of battery chemistry. In the past, lead-acid batteries and gel batteries have made up the majority of the solar street light market, but along with the gradual improvement of lithium-ion technology, lithium batteries are favorably received by the market of solar street light nowadays. In fact, lithium battery is a wiser investment for solar street lights in view of its various advantages over traditional batteries such as lead-acid batteries.Why lithium battery is recommended for solar street light?With the development of battery technology, lithium battery is well known as a kind of rechargeable battery that are extremely versatile and suitable for the use in many different types of electronic devices from consumer electronics such as laptops to electric vehicles like golf carts, camper van. In addition, as an environmentally friendly technology, the long -life, temperature resistance, and safety features given by the recharge ability of this battery also allows it become growing popular in solar power battery storage, communication base station, etc. Here are some benefits of using lithium battery to power your solar street light.Good Temperature resistance Temperature is of great importance for the battery life. Extreme temperature will accelerate the loss of service life of batteries. High temperature can have a greater impact on the traditional lead acid solar street light batteries than lithium solar street light batteries. Temperature which is more than 20°C can reduce the lead battery’s lifespan very fast. On the contrary, lithium battery can tolerate temperature up to 45°C. Cold temperature increases the internal resistance and lowers the capacity. Nevertheless, lithium-ion batteries have much better performance at colder temperatures than lead-acid batteries. At 0°C, for example, a lead-acid battery’s capacity is reduced by up to 50%, while a lithium iron phosphate battery suffers only a 10% loss at the same temperature.High Cycle EfficiencyThe efficiency of solar street lights is related to the cycle efficiency of batteries. Lithium batteries efficiency is near 95%, however, it is about 80-85% in AGM or GEL batteries. It means that if you want to charge 1Kw, a lithium-ion battery loses 5% to power the solar street lights but the AGM battery loses 15-20%. In the case of a solar street light, at least 10% more solar panels are needed to power the same load if using lead-acid batteries. By contrast, a much higher efficiency of lithium batteries can explain why lithium battery are more commonly used at present.Discharge Cycles and Depth of Discharge toleranceThe DOD (Depth Of Discharge) means how long your solar street light can work. It is generally accepted that the practical DOD (Depth of Discharge) for a lead-acid battery is 40%-50% while a lithium-ion battery could be kept DOD near 80%. If you want to use 50% of a battery’s capacity, lead-acid battery has around 1000-1500 cycles whereas the lithium-ion battery can last for 5000 cycles. It means that a lead-acid battery will have to be replaced 4-5 times more often than lithium batteries.Lithium Batteries ComplexityFor the above advantages of lithium-ion battery, you might wonder why some people choose lead-acid batteries. It is because the lithium batteries are more sensitive to over discharge and overcharge which requires more advanced electronics to detect the status of batteries. At UFO Battery we have the knowledge and skills to deal with this complexity. That is why all of our products are equipped with a dedicated battery management system that optimizes both charging and discharging to maximize battery life.Read More>>
