As being an industrial maintenance mechanic within the last two decades, We have seen maintenance as well as other trades revolutionized by the introduction of cordless tools. They help save time, money and can be used almost anyplace. Technologies have come alomg way since the beginning of cordless tools. Larger voltages have ended in more power and longer run times from batteries have helped the tools become well-liked by tradesmen.
One of the only knocks against cordless tools has become the body weight. The typical 18 volt cordless drill has weighed up to six pounds in the past. The tool manufacturers have heard the tradesman who would like more power, more run time, and a lighter tool. The creation of lithium-ion batteries for the cordless tool industry addresses the 3 of such consumer needs. Lithium-ion batteries offer a reduction in cordless battery weight of 25-40 % as well as a total tool weight of up to 25 %. In the past, most of the NiCad and NiMH batteries were required to extend up in to the handle of tools such as cordless drills, reciprocating saws, and circular saws. This all translated into more overall weight for that battery and tool. With the creation of lithium-iom technology, manufacturers can pack more power in Lithium Ion Battery Pack which is the same size/weight as the NiCad or NiMH or fit the same power because the NiCad or NiMH in a smaller battery pack.
Batteries today are omnipresent today they are invisible to us. Running in cars, cameras, drones, bulbs, mechanical tools, inverters, ships, trains, airplanes, windmills as well as in satellites. The basic science behind the battery is chemical energy converting to electricity containing three main components: Anode, Cathode, and Electrolyte. The revolution within 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) and then finally to Lithium-ion battery. These are available in all sizes and shapes depending on the necessity along with its possibly packed power capacity.
Working: The Lithium-ion battery pack contain graphite, oxygen, metal, not to mention lithium, which runs in a cycle of discharging and charging. While producing energy, the lithium moves back to the positive cathode over the electrolyte, and even though charging, the ions go on to the positive anode. This cycle repeats during the period of time and degrades the potency in 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. It is a vast difference for any small, portable and noiseless rechargeable battery.
Concern Parameters: The 10 parameters that a 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 shelf-life. In early stages, the expense of a Li-ion battery was $3000 per kWh, while Lead-acid battery cost $150 per kWh. But over time, due to multiple benefits of Li-ion battery pack, being 150Wh/kg 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 the cars.
NEW ERA: In 2005, there was an overall of around $4900mil inside the sales of lithium-ion batteries whilst in 2015 it really is spiked to $15200mil wherein $4800mil is in automotive alone. It is expected to reach 10% on the total number of cars on the road to be battery EVs by 2020 from .3% today as well as 35% by 2035. It comes with an even higher growth rate in China, Europe, and Japan as compared to the US. Statistically consuming 1900TWh for Li-ion battery pack by 2035, which is equivalent to power the entire people for 160days.
FUTURE: There is still much to develop battery technology as over the years we haven’t develop anything beyond lithium-ion battery packs configured in parallel or series to offer the required voltage, power density, and capacity. We sure have changed the contents and also the proportion of the mixture of raw materials to improve the capabilities, but nejbjh continues to be plenty of work that needs to be placed into battery technology. The targets are going to reach over 700Wh/kg for that of 400Wh/kg we have been on today. By 2020, 75% of batteries are required to contain cobalt, in some capacity at the very least in addition to better anodes and enhancing electrolytes.
In the long run, lithium ion battery pack will be cheaper and a lot more efficient up to the current ones. Moreover, Lithium Air technology is within cultivation, which shall have 10times the power density than Li-ion. The entire 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.
