I thought Europe banned them in the mid 90s for environmental reasons.

Amazingly this article -so far- misses what probably is the most needed information; How user's usage, 1st charge and charging practices vary accordingly different battery types. At 2012 most users have yet to learn that lithium ion batteries are best not discharged below 20-30% capacity, very different from the NiMH requirement of full discharge...

Another vote for the Lithium Phosphate LiFePO4 and LiPO

Li-Ion and more advanced technologies are already overtaking many applications of NiMH and NiCd also.

A good article, but shouldn't it include Lithium Iron Phosphate batteries, they seem to be the rising chemistry for a lot of applications?

@afpele: I am also looking forward to part 2 of this article. Continuing in a similar theme, it would be nice to have a writeup on printed battery technology and their maturity to be deployed in end products in low power applications. MP Divakar

@Frank Eory & IFindNickNamesAnnoying: you are both correct, NiCd have been phased out in EU countries now, under the "batteries directive" the sale of except for medical use, alarm systems, emergency lighting, and portable power tools. This last category is to be reviewed soon. In the US, part of the battery price charged goes toward recycling. But we all know many states are lacking in recycling e-wastes and consumers are also complicit in adhering to recycling. MP Divakar

Good question and based on the numbers I think your guess of charge - discharge is a good one.

There is quite a lot of information out there pointing out that the real NICAD memory effect is largely gone in modern designs. Damage from overcharging is NOT the memory effect. The use of a smart charger for both NI-MH and NICAD can eliminate overcharging. I hope you're going to go into that next week.

Good article, but the material seems a bit dated. NiCd is in steep decline -- are those batteries even allowed in Europe anymore? And NiMH has mostly been superseded by Lithium ion for nearly all consumer portable applications.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Timesí Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
