Lithium Ion Battery Pack – Common Questions..

As an industrial maintenance mechanic within the last 20 years, We have seen maintenance and other trades revolutionized by the creation of cordless tools. They help save time, money and can be used just about anywhere. Technologies have come alomg way since the early days of cordless tools. Larger voltages have resulted in more power and longer run times from batteries have helped the tools become popular among tradesmen.

One of the only knocks against cordless tools has become the load. The normal 18 volt cordless drill has weighed as much as six pounds before. The tool manufacturers have heard the tradesman who would like more power, more run time, as well as a lighter tool. The development of lithium-ion batteries for the cordless tool industry addresses all three of those consumer needs. Lithium-ion batteries offer a decrease in cordless battery weight of 25-40 % along with a total tool weight of up to 25 %. Previously, many of the NiCad and NiMH batteries needed to extend up in to the handle of tools like cordless drills, reciprocating saws, and circular saws. All of this translated into more overall weight for your battery and tool. With the growth of lithium-iom technology, manufacturers can pack more power in Custom Battery Packs this is the same size/weight since the NiCad or NiMH or fit exactly the same power since the NiCad or NiMH in a smaller battery pack.

Batteries today are omnipresent today that they are invisible to us. Running in cars, digital camera models, drones, bulbs, mechanical tools, inverters, ships, trains, airplanes, windmills and even in satellites. The basic science behind battery is chemical energy converting to electricity containing three main components: Anode, Cathode, and Electrolyte. The revolution inside the battery over the years are through several stages of chemical combinations and implementations. Beginning with Voltaic Pile to Daniell Cell, then from Lead-Acid to Nickel Cadmium battery, further evolving to Alkaline Battery, Nickel-Metal Hydride (NiMH) then finally to Lithium-ion battery. These are available in all shapes and sizes as per the need along with its possibly packed power capacity.

Working: The Lithium-ion battery pack include graphite, oxygen, metal, and naturally lithium, which runs in a cycle of discharging and charging. While producing energy, the lithium moves to the positive cathode throughout the electrolyte, and even though charging, the ions proceed to the positive anode. This cycle repeats over the course of time and degrades the potency from the ions in offering the electric charge. The lithium-ion has 250Wh/kg (Watt-hours per kilogram) of energy while NiMH has mere 90Wh/kg. This can be a vast difference for a small, portable and noiseless rechargeable battery.

Concern Parameters: The 10 parameters that the Lithium-ion battery pack’s development covers are high specific energy, specific power, affordable cost, longer life, better safety, wide temperature operating range, non-toxic, fast charging, lower self-discharge and longer life expectancy. In the early stages, the price of a Li-ion battery was $3000 per kWh, while Lead-acid battery cost $150 per kWh. But over time, because of multiple advantages of Li-ion battery pack, being 150Wh/kg a lot more than the NiMH, the fee is dramatically falling costing now $150 to $240 per kWh. Tesla’s goal would be to reach $100 per kWh on lithium-ion battery packs for that cars.

NEW ERA: In 2005, there was clearly a total of about $4900mil inside the sales of lithium-ion batteries while in 2015 it is actually spiked to $15200mil wherein $4800mil is at automotive alone. It really is supposed to reach 10% on the total variety of cars on the road to be battery EVs by 2020 from .3% today and to 35% by 2035. It comes with an even higher growth rate in China, Europe, and Japan when compared to the US. Statistically consuming 1900TWh for Li-ion battery pack by 2035, which is equivalent to power the whole individuals for 160days.

FUTURE: There is still a great deal to develop the battery technology as through the years we haven’t develop anything beyond lithium-ion battery packs configured in parallel or series to offer the desired voltage, power density, and capacity. We sure have changed the contents and the proportion from the mixture of raw materials to enhance the capabilities, but nejbjh is still a lot of work that has got to be put into the battery technology. The targets are to reach over 700Wh/kg to that particular of 400Wh/kg our company is on today. By 2020, 75% of batteries are expected to contain cobalt, in a few capacity a minimum of in addition to better anodes and enhancing electrolytes.

In the end, lithium ion battery pack is going to be cheaper and much more efficient over to the existing ones. Moreover, Lithium Air technology is at cultivation, which shall have 10times the vitality density than Li-ion. The world for lithium ion battery pack isn’t likely to end for the next half century at the very least, rendering it the best developing area in technology.
