Lithium battery problem worsens

11 February 2016

Lithium batteries are amazing things. They've finally made many previously impractical devices (such as electric vehicles) a reality.

By offering previously unheard of energy densities in terms of energy to weight and energy to volume ratios, the lithium battery has become an increasingly important aspect of modern technology.

Despite the fact that today's laptop computers are faster than ever, they now run for longer than ever on a single charge; something that is largely attributed to the switch from old nickel-cadmium or nickel metal hydride batteries (NiMH) to lithium ion types.

Neither the Tesla Roadster nor the Model S would be able to deliver the eye-watering performance or range that they do if they contained older lead-acid or NiMh cells.

Even your smartphone would not be a practical reality without the power of lithium polymer batteries that can squeeze many watt-hours of capacity into a cell that is just a few millimetres thick.

Forums are up!

Yes, people have been complaining about the lack of forums for months now so I finally got off my chuff and finished the transition to the new server and the commissioning of the new forums.

Unfortunately you will have to re-register, it just wasn't practical to transition the IDs from the old server -- although the old stuff will be maintained in a "read-only" capacity for some time to come.

So, if you want to "have your say" then register at the new forums using the magic word Aardvarkroxs when asked for it.

Take a moment to introduce yourself to the rest of the Aardvark community and pretty shortly I'll be expanding the number of forums to encompass a number of areas that are regularly discussed on this site.

The contact form is not yet working (got to rejig the CGI scripts) but if anyone wants to email me they can send their communications to editor at this domain or PM me via the forums.

Oh yes, if anyone wants a bit of a plug then the sponsorship space is now up for grabs. Until someone is prepared to offer a donation for the use of this space, I'm happy to offer a free plug to anyone who wants to send me a suitable 150x150 graphic and link.

Stay tuned!

Sorry, the headlines haven't been updated today
