Why are Lithium-Ion battery packs popular? Of all the metals, lithium is the lightest. It has the highest electrochemical potential and provides the highest energy density per weight. G.N. Lewis et al pioneered the idea of Li-Ion battery in 1912. However, it was only in the early 1970’s, that the world got its first non-rechargeable lithium batteries for commercial use.   Qualities of Lithium-Ion Batteries Due to the fact that it has the highest energy density, the Li-Ion battery has an edge over the normal nickel cadmium battery. Due to improvements incorporated in the active compounds of the electrode, the Li-Ion battery has an electric power density which is almost three times more than that of the nickel cadmium battery. Besides this, the load capacity of lithium battery is also appreciable. It has a flat discharge curve which gives you the chance to use the saved power in a voltage range of your choice. One of the noteworthy qualities of Lithium-Ion battery pack...

Is Lithium-ion the Ideal Battery? For many years, nickel-cadmium had been the only suitable battery for portable equipment from wireless communications to mobile computing. Nickel-metal-hydride and lithium-ion emerged In the early 1990s, fighting nose-to-nose to gain customer’s acceptance. Today, lithium-ion is the fastest growing and most promising battery chemistry. The world is becoming increasingly electrified. Not only are developing countries increasing the availability of electricity to their populations, but the electrification of existing transportation infrastructure is proceeding at a rapid pace. By 2040, over half of the cars on the roads are projected to be powered by electricity. A Brief History of Batteries Batteries have been a part of our daily lives for a long time. The world’s first true battery was invented in 1800 by the Italian physicist Alessandro Volta. The invention represented a remarkable breakthrough, but since that time there have been only a h...

Lithium batteries are advancing rapidly, and they provide longer use times than nickel and lead based batteries. Their use has been adopted as the standard for most of the spy cameras, and other electronics on the market today. Here are six tips to extend the life of your lithium-ion based electronic device. Here are six things you can do to increase the life of your lithium-based battery. 1. Avoid constant full discharges: Lithium batteries prefer a partial discharge, over a full discharge. You should not frequently fully discharge the batteries, rather charge the battery more often, if possible, daily to insure a long life. 2. Recalibrate: We suggest a full discharge every 30 charges for batteries with fuel gauges, like laptops and mobile phones to recalibrate the battery. Just let it run until it stops, then recharge. 3. Laptop computer uses: If you keep the battery in your laptop for everyday use, and power it from the wall socket, unplug the power every few days and let it r...

A lithium iron battery is a lithium ion battery which uses iron phosphate (LiFePO4) as cathode material. But first, we must understand what a lithium battery is to get a better idea of the advantages of a LiFePo4 battery. Lithium-ion batteries (or simply lithium batteries) are batteries which use lithium based material as a cathode and a variety of other materials (most commonly graphite) as anode. These batteries are commonly found in portable devices, such as cellphones, digital cameras, and others due to its light weight, small form factor and long battery life. Lithium batteries have the advantage of using lithium, which is the element that is most easily oxidized. It means that it can easily give up an electron, which is then used by the circuit to power itself. The easier electrons are taken from a battery, the more efficient it becomes, hence accounting for its longevity. In addition, lithium is the lightest known metal, therefore it allows for portability and the materia...

According to Japanese media reports, on October 4th, local time, the Japanese dragon-class conventional submarine No. 11 “Phoenix Dragon” was launched. The boat used lithium batteries for the first time. It was called “revolutionary breakthrough” by submarine batteries. As we all know, the battery is the main power source of the conventional submarine, and it is also the backup power supply and emergency power supply for the nuclear submarine. Therefore, the performance of the battery directly determines the submarine performance and combat capability. If the battery performance is not good, the power supply is insufficient, the submarine will not run fast, the mobility is greatly limited, the charging time is longer, and the risk of being exposed is greatly increased. For this reason, the development and application of submarine batteries have been highly valued by the world’s submarine manufacturers. The lead-acid battery has mature technology, hi...

EU Energy Commissioner Sevkovic said recently that the European Union plans to provide tens of billions of dollars in battery research and companies building large-scale battery factories in order to catch European battery production to compete with Chinese and American competitors. “The European Union launched a battery offensive!” Germany’s “Economics” magazine reported on the 15th that EU energy commissioner Sevkovic said recently that the EU plans to provide tens of billions of subsidies for battery research and the construction of large battery factories in order to make European batteries Production catches up with competitors in China and the United States. During the Paris Motor Show earlier this month, Sevkovic said to the outside world, “The future will be the era of electrification, Europe must keep up with the development of battery technology.” Sevkovic said that the future European battery market will It reached 250 billion...

Since the conventional electrolyte partially solidifies at temperatures below 0 ° C, the capacity of the lithium ion battery is drastically reduced when it is operated under low temperature conditions, thus limiting its application under extreme conditions. In order to improve the low temperature performance of lithium ion batteries, a lot of research work has focused on improving the conductivity of electrolytes. Figure 1 is a process of synthesizing the additive. Mainly, the ionic liquid molecular chain is grafted onto the polymethyl methacrylate (PMMA) nanosphere by reaction to form a brush-like main structure, and then the structure is dispersed in ethyl acetate (MA). And a new electrolyte system is formed in a mixed solvent of propylene carbonate (PC). As shown in Fig. 2a, the conductivity of the electrolyte decreases as the temperature decreases, and the conductivity of the electrolyte containing ethyl acetate is much higher than that of the electrolyte using only propylene...

Australia and Chile are the two largest lithium mining countries in the world. However, due to different geological and climatic conditions, they differ greatly in the way they produce lithium. The Greenbushes mine in Western Australia supplies one-third of the world’s lithium mines. The production process involves the extraction of hard rock and on-site preliminary treatment, including crushing, grinding and flotation. The lithium mine in Chile needs to extract lithium-rich brine from the salt lake. The brine was concentrated in the evaporation pond for several months and then subjected to on-site preliminary treatment. Chile’s main lithium mine is located in the north of the country and is part of the so-called global “lithium triangle”, which includes the border areas of Chile, Argentina and Bolivia. ※ Western Australian lithium production will grow strongly The Greenbushes lithium mine is undergoing project expansion. In the past two years, two mines in the easte...
