Re: NiCad vs. Li ion Batteries
From the info I have, I think there is an argument favoring Liion
batteries over NiCad in terms of environmental impact, but I haven't
spent enough time researching it to make that argument here. I do have
a number of resources (some of which I can email to you on request)
that might help with your decision:
Preventing Waste from Batteries (Includes environmental info on
different types of rechargables)
An EU report: Substitution of Rechargeable NiCd batteries
There was an article in Sci of Total Env (2003 Jan
"Impact on global metal flows arising from the use of portable
rechargeable batteries," by Carl Johan Rydha and Bo Svard.
"Life-Cycle Environmental Comparison of Primary and Secondary
Batteries," Rebecca Lankey and Francis C. McMichael, Proceedings of
the 1999 IEEE International Symposium on Electronics and the
Environment, Danvers, MA, May 1999.
Rebecca Lankey actually did her thesis on this topic--an LCA looking
specifically at NiCads but also comparing them to others. I can email
this to you if you are interested.
In 2000 I did a survey of battery MSDS's and summarized the different
metals and their concentrations in NiCd, NiMH, LiIon, and ZincAir
batteries. I can email this to anyone who wants it.

Subject: NiCad vs. Li ion Batteries
I recently got the following request and don't have any idea how to answer
it. It sounds like paper vs. plastic bags. Do any p2techers have a
preference and why.:
I work for a company that designs power tools for Ryobi, Ridgid, and
Milwaukee. I was currently working on a project that would possibly switch
over a popular NiCad rechargeable battery pack to Lithium Ion in a cordless
tool line. I was interested to know about environmental implications to
this decision. I was told Li batteries where much better from an
environmental standpoint than traditional NiCad. I hope this is the case.
I'm slowly trying to make my company more aware of environmental
implications on products they make and how they are manufactured. Any
information you can provide or connect me to would be very appreciated.
Thanks for any help you can provide.
