Why Lithium Ion

mEtoke2 · 11-23-2008, 04:36 AM

The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. There is potential for higher energy densities. The load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge. The high cell voltage of 3.6 volts allows battery pack designs with only one cell. Most of today's mobile phones run on a single cell. A nickel-based pack would require three 1.2-volt cells connected in series.

Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed.

Despite its overall advantages, lithium-ion has its drawbacks. It is fragile and requires a protection circuit to maintain safe operation. Built into each pack, the protection circuit limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge. In addition, the cell temperature is monitored to prevent temperature extremes. The maximum charge and discharge current on most packs are is limited to between 1C and 2C. With these precautions in place, the possibility of metallic lithium plating occurring due to overcharge is virtually eliminated.

Because windmills are too heavy to carry around...LOL The atomizer does not care what it is hooked up to as long as it is the correct volt, amps, dc current...... I am sure others can explain the requirements for the atomizer, but the reason for one type of battery or another is based on it ability to meet the requirements of the atomizer to produce vaper. Lithium Ionone batteries are the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. This makes them good for this type of application.

I had a battery go haywire the other day. the atomizer was glowing! I realized that isn't right and not just a cleaning thing...my gosh, if I had waited for it to clean it would have burned up my atomizer and my hand! the switch inside went bad, I think and it isn't a new battery so I am not gonna complain about it. But, it is something to look out for after a few months...if yours lasts that long.

What type of voltage does an atomizer require to perform at optimum levels?

The reason I ask is because I have one battery that charges up to 4.1volts and then the dse601 indicates that the battery is dying after about 30 puffs. I checked it on the multimeter and it still read 4.1 volts. So I cant understand what is triggering the low battery warning.

My other battery shows the same voltage of 4.1 volts, but it goes all day long before the indicator starts to blink.

It's probable you are measuring the voltage off load. A battery without any load can easily read over 4 volts but drop dramatically when actually doing work.
