This week in batteries (TWiB): A Brief History of Batteries- Part 1
http://thisweekinbatteries.blogspot.com/2010/08/brief-history-of-batteries-part-1.html
This week in batteries (TWiB). Monday, August 30, 2010. A Brief History of Batteries- Part 1. When I was around 13 years old I remember learning about primary batteries in school. This was about the time when I had also encounter lead-acid batteries and had realized that the car starter battery is being charged periodically. I began to wonder why some batteries could not be recharged while other could. Thus began my fascination with batteries. The topic I’m discussing is technical. I’ve t...This blog pos...

This week in batteries (TWiB): If your cat has nine lives, shouldn't your battery have at least two?
http://thisweekinbatteries.blogspot.com/2010/11/if-your-cat-has-nine-lives-shouldnt.html
This week in batteries (TWiB). Monday, November 22, 2010. If your cat has nine lives, shouldn't your battery have at least two? Let’s see if you can answer this pop quiz: How much capacity fade can you tolerate in your battery before you consider it “dead”? The answer (as usual) depends on the application. You are not about to pay for another battery. And running your car with a long cord connected to an outlet can be a bit problematic. But, as definitions go, most manufacturers will consider a battery t...

This week in batteries (TWiB): February 2013
http://thisweekinbatteries.blogspot.com/2013_02_01_archive.html
This week in batteries (TWiB). Wednesday, February 6, 2013. Are you charged up? Because we are ready to go! But its not just about the technology. If you don't have a technology that satisfies a market demand, then its equally likely that the company will not succeed. And in some markets your efforts may be stymied by the regulatory policies that may prevent the battery being developed from being used. So how does one learn about all of these things? CalCharge has teamed up with San Jose State to start w...

This week in batteries (TWiB): December 2012
http://thisweekinbatteries.blogspot.com/2012_12_01_archive.html
This week in batteries (TWiB). Saturday, December 15, 2012. And here are the lucky winners. I have a new found respect for movie actors (not stage actors, mind you). Being in front of a camera makes you self conscious in a way being in front of an audience does not. I can see why Arnold stuck to one liners! The questions were all very interesting ranging from how we can make a battery that is five time better and five times cheaper to how one can become a battery scientist (start a blog? But, let us get ...

This week in batteries (TWiB): Battery Rules.
http://thisweekinbatteries.blogspot.com/2010/02/battery-rules.html
This week in batteries (TWiB). Sunday, February 28, 2010. I’ve been reading Michael Pollan’s new book titled “Food Rules” and thinking about his Haiku on food which goes: “Eat food. Not too much. Mostly plants.”. Don’t charge them too high. Don’t swing them too wide. Keep the temperature low to extend their life. Lithium ion batteries are not all equal. A battery from A123 will be different from one from Panasonic. So use these rules. For your cell phone and laptop batteries. Turns out that while a small...

This week in batteries (TWiB): A Brief History of Batteries- Part 2
http://thisweekinbatteries.blogspot.com/2010/09/brief-history-of-batteries-part-2.html
This week in batteries (TWiB). Monday, September 6, 2010. A Brief History of Batteries- Part 2. Last week I posted on the need to understand the. History of battery development. And how this will influence the future of batteries. We conclude today with Part 2 of this series. Chapter 3: If it is sparingly soluble, then lets talk. But if the lithium thionyl chloride is not a rechargeable battery and the zinc-manganese oxide is not a rechargeable battery, then why is the lead acid a rechargeable battery?

This week in batteries (TWiB): Did I say “Pull the Plug”? Meant to say “DO NOT pull the plug”
http://thisweekinbatteries.blogspot.com/2011/01/did-i-say-pull-plug-meant-to-say-do-not.html
This week in batteries (TWiB). Monday, January 31, 2011. Did I say “Pull the Plug”? Meant to say “DO NOT pull the plug”. Be a mea culpa post. It is rare that I’m wrong; it is even rarer that I admit it! So listen up folks. In the early days of this blog, one of my dedicated (? Readers had asked me about the urban myth about not keeping the laptop plugged in to extend the life of the battery. In response, I had written a post titled “ Pull the plug, your battery will thank you. I have another laptop which...

This week in batteries (TWiB): A Moore’s law for batteries? Maybe not.

This week in batteries (TWiB). Monday, February 15, 2010. A Moore’s law for batteries? Its 6:00 pm on a Monday evening and the traffic seems horrendous. You decide to whip out your iPhone and log on to Google Maps to check out alternate routes when you see the dreaded warning that your battery is out of ‘juice.’ You curse the guys who work on batteries for not doing their jobs better and wonder if batteries have actually improved in your lifetime. Sound familiar? If you take your cell phone lithium-ion b...

This week in batteries (TWiB). Saturday, December 8, 2012. Ask and you shall receive. maybe. This is a bit embarrassing. TWiB is getting updated twice in a week!
