Lithium-Iron Batteries
Has anyone had experience with lithium-iron batteries? I'm considering buying a Shorai for one of my motorcycles.
I've had a lot of batteries die from sitting through eight months of winter, and hoping that one of these will last a bit longer. |

Never heard of them before. I wonder if they were invented as a result of a typo. (Yes, I just learned they are a thing).

Would it be cheaper to buy some sort of trickle charger and keep the thing plugged in all winter? They must make such things.

Trickle down electricity didn't work under Reagan, and it won't work now.

Lead acid batteries need no special electronics. If the recharge voltage is regulated, then that old technology battery will never overcharge. Lithium batteries have no such internal protection. A constant recharge voltage to a lithium battery can cause battery explosion. So that Lithium needs a recharge regulator (probably internal) to avert explosion. |

Yes. And, yes, they do.

A nation that innovates owns the battery industry. We have only just started to understand a technology even used in the 1970s. That even made possible 24 hours HBO.
Some current technologies are the original Lithium Ion, Lithium Ion Polymer, and Lithium Iron Phosphate. Variations exist for each chemistry. Each varies with temperature, load, recharge time and algorithm, ability to hold a charge, weight, power density, cycle life, energy density, and safety. All expensive solutions to a problems made irrelevant by a simpler solution. That old technology battery has one limitation. It must be recharged, at longest, monthly to not self destruct. Some trickle chargers recharge deeper into the little parts of a battery. Others only top off the battery resulting in a recessionary and eventually failing battery. In this new lithium economy, trickle charging is often destructive. Last edited by tw; 10-11-2012 at 01:42 PM. |

I enjoyed this editorial that follows along TW's ideas oft-exressed about innovation...

Rare earth metals are not really rare. Rare earths are difficult to extract from other 'dirt'. It is the extraction - not the element itself - that makes the element rare. How to solve a shortage of rare earth? Innovate. Develop new extraction methods.
Who create new jobs, new industries, new markets, and destroy recesssions? The nations that innovate. Rare earths are but another example because so many other new innovations (including superconductivity and disk drives) require them. The world is full of silicon and lithium. Only nations that innovate aggressively create new jobs from products also based in these 'more common' elements. The elements themselves are not important. How those elements can be extracted and used are important. Advantages of a lithium battery would be lost on a motorcycle. But then lessons from Clayton Christensen's "Innovator's Dilemma" may apply. Sometimes a product that makes little sense becomes the best solution. Last edited by tw; 10-16-2012 at 04:47 PM. |
