Li-Ion and the Li-Pon are two widely used batteries. This two variant gets their usages in a wide range of products. From laptops to cell phones, this battery made the life of humans apparent and sorted. And today, we are here to talk about these products in comparison mode. This will offers the stranger to know in detail or in vague. Additionally, we should have an idea of what we are using. Therefore let us take a more in-depth look at the comparison to learning more about these items.
Li-Ion And Li-Pon, Let Us Check Them Out-
Li-ion (as in the basic version, aka lithium cobalt cells) is obsolete due to the severe fire risk due to thermal runaway when overcharged, over-discharged, or used in series. Don’t use basic Li-ion cells; they are dangerous when overdriven in any way.
Li-Po power is probably cheaper in bulk. However, it has a significant risk for fire when on charge after a hard impact. This was first discovered by the R/C modelers who used Li-Po packs in their planes and helicopters but suffered fires that burnt outbuildings when charging the batteries overnight after a massive impact on the ground.
On the other hand, Li-Mn cells – the ‘basic’ lithium cell technology today for discrete batteries – will suffer thermal runaway too when severely abused. Battery packs that use them will need cryogenic cooling (this probably applies to all lithium-based technologies).
As an example, the new Boeing Dreamliner had multiple fires that grounded them until they threw out the lethally incompetent battery pack design featuring lithium cells. Maybe someone didn’t tell the fool that designed the battery packs that you can’t smash them into the ground, and you can’t overdrive them, and you can’t operate them without cryogenic cooling systems.
At least it’s an eye-opener on jet airline safety: you’d naturally assume that they have the best engineers, with excellent experience and the latest information. Instead, they had some know-nothing cretin who had never worked with lithium cells – these are all things anyone who has worked with lithium cells would know by heart.
Some More Of The Topic
So: use Li-Po for cheapness but be extremely careful about impacts. Keep temperatures down, and this may mean efficient cooling systems. Be very careful about the architecture – use proven systems with a known good history.
Use Li-Mn or Li-hybrid for high performance, but temperature control is absolutely critical. You will want thermal monitoring right in the center of the pack. You may well need cryogenics (liquid cooling). High-power lithium cell packs will need cryogenic systems as an integral part of the system: when you install or remove the box, it should come complete with the tubing integrated within the pack, and you will connect/disconnect the pipework as well as the electrical connections. Use only proven architecture (proven safe cell size/type and series/parallel network design).
Don’t try and cobble together your own self-designed battery pack, you are asking for a fire. The first step is to find a proven safe design. Avoid whatever those idiots put in the Dreamliner, for example.
