The particular Interesting Thing About Lithium Batteries

0 1

The interesting point about batteries is that you could make one out of a spud. Or a tomato. Or even lime or lemon. Any liquid or moist object with sufficient ions to be electrically conductive can serve as the electrolyte for any cell (see Wikipedia. com). You just need to place two electrodes made of various metals into the moist item, and a chemical reaction occurs when the two metals react through the moist cell, also known as the potato. Cool, huh? Naturally, this type of “battery” involves no real practical employ except to maybe electrical power a small clock for a quite short amount of time. The actual Interesting Info about 48V 100Ah LiFePO4 Battery.

A battery is stored chemical energy converted to usable electricity as soon as the battery terminals are related via some material that could transfer(conduct) and allow the two precious metals to react chemically. Similar to Nickel and Cadmium in the NiCad battery. How much energy you get (volts) depends on how much “chemical reaction” you might have between the two metals. It’s for this reason that Lithium power packs are the “latest and greatest” thing since powdered milk products.

Lithium is a highly reactive alkali metal. Lithium can react if omitted in open, moist surroundings. Combining with the hydrogen from the water molecules in the air, it can turn from a whitish material to a black tarnish before your eyes. This is why when lithium is saved in its pure state, within is stored under essential oil to keep it from responding.

Lithium is also highly burnable, so if it is already burning up, throwing water on it will simply make it burn more. Lithium metal needs to be doused with special chemicals to put out your flames. Lithium is also the actual lightest weight metal (number 3 on the Periodic Desk of elements). Those two features, lightweight and lots of potential energy, make Lithium an excellent metal to use in an electric battery.

Lithium’s highly reactive function is also a downside in the electric battery-making industry. Lithium battery packs in computers have “ignited” because of their high reactivity. Dell Computers recently had a massive laptop battery recall (the computer I am inputting on was affected). Lithium batteries give off a lot of temperatures and have been known to self-combust. The actual recall cost the industry megabucks, but Lithium’s advantages outweigh its disadvantages, and Lithium cell technology is advancing rapidly.

“In an interview with BusinessWeek on Feb. 16, Leader Katsuaki Watanabe confirmed which Toyota’s third-generation hybrid vehicles, due out in late 08 or early 2009, use lithium-ion batteries. Lighter and much more powerful than the current dime metal hydride packs, the brand new batteries will help make for much more fuel-efficient hybrids… “We can produce the battery in time, inch he says… “We are aiming at reducing, through the half, both size as well as the cost of the third-generation mixed system, ” says Watanabe. ”

For most people using battery packs, the life of the battery is considered the most important aspect. So how long will it last before I have to recharge/replace the idea? Disposable batteries reduce from 10-20 per cent from their original charge every year, far more if stored at really high temperatures (battery life might be extended by storing these questions cool place). So the power packs that you buy at the $ Store will not necessarily require that long; always check the manufacturer’s date about the batteries that you are looking to purchase.

Normal rechargeable batteries self-discharge more rapidly when compared with disposable batteries – approximately three per cent per day. This rate can decrease in intense temperatures, so keep this in mind if you store your rechargeable, battery-operated electrical power tools/flashlights in your garage. Normal rechargeable batteries also degrade by way of use. Low capacity Pennie Metal Hydride(NiMH) and Pennie Cadmium(NiCad) rechargeable batteries can be charged for approximately a multitude of cycles before pooping from you. Typically a longer, more slowly charge (overnight) will result in an extended battery lifespan.

There is also an elaborate “memory effect” in terms of batteries. The memory effect occurs in NiCad and NiMH batteries when crystals build up on the electrodes, reducing the active surface area that will get charged (Wikipedia. com). Preparing when batteries do not get completely discharged before they are charged up again. NiCad batteries should always be completely discharged before they are charged up again because they suffer more through the “memory effect” than NiMH. The advantage of using Lithium-ion batteries is that, like a younger dog, they do not have a “memory effect”. Charge them when you want; they will always be completely charged and ready to run.

In summary, the three most commonly used Power Tool Battery packs in order of performance:

3. NiMH:

-performs the most severe in cold temperatures

-has the shortest run period

-highest self-discharge level

-lighter in weight than NiCad

2 . NiCad:

-performs within cold temperatures to 20F

-lower self-discharge rate compared to NiMH

-has a lower self-discharge level than NiMH

-heavier in weight

-suffer the worst from the “memory effect” if not fully discharged ahead of charging.

1. Lithium Ion: -lightest in weight

-perform well on temperatures as low as zero diplomas Fahrenheit

-have the highest volume of life cycles

-lowest self-discharge rate

-have a more speedy charge time

-do not necessarily suffer from the dreaded “memory effect.”

**BUT: permanent injury can occur to LiIon power packs if stored at too-low discharge level, so be mindful and keep these charged effectively. Also, They start busting as soon as they leave our factory. Be sure to check the manufacturer’s particular date on the batteries before you order.
