Arthur T Knackerbracket has found the following story:
A novel, low cost and green lithiated tin vanadium oxide compound has been synthesized via simple, economical and scalable sol-gel method to replace the conventional graphite as electrode material for lithium-ion batteries. This material has a long technological lifespan as it can last long as long as it is well-kept under moisture free condition.
Nowadays, comfortable modern lifestyle requires portable electronic devices such as mobile phones, laptops, digital cameras, video camcorders and so on. These gadgets contain the rechargeable lithium-ion batteries. Without this energy storage unit, the devices cannot function.
A Li-ion cell consists of cathode, anode and electrolyte. The electrolyte is a liquid that has been added with a lithium salt. Inside the liquid, the salt exists as the positively charged cations and negatively charged anions. For example, lithium chloride (LiCl) will exist as Li+ cation and Cl- anion. New electrode materials have been intensively studied in order to improve the electrochemical properties and meet the ever increasing demand for Li-ion batteries.
Commercial Li-ion batteries comprise a lithiated metal oxide negative terminal (cathode) such as lithium cobalt oxide (LiCoO2), a graphite positive terminal (anode) and a Li-ion liquid electrolyte such as lithium chloride (LiCl), lithium hexafluorophosphate (LiPF6). However, the formation of dendrites at graphite anode during the charge-discharge cycles give rise to serious safety concerns (thermal runaway) even at low temperature conditions.
Extensive research has been carried out to find a replacement for graphite as anode material. In this work, lithium tin vanadium oxide (LiSnVO4) has been synthesized via sol-gel method. The research was directed by Prof. Dr. Abdul Kariem Arof, department of Physics, faculty of Science, Universiti Malaya with a team of researchers. "We do not want to involve sophisticated chemistry", said Prof. Arof. "It should be a straightforward, simple and inexpensive application. Therefore, it is easy to scale up making it a fully affordable application".

I'm an average American: jobless, homeless, and living in a tent under a bridge. I find a stolen shopping cart is sufficiently portable for all my belongings. I connect to the internet with a ten-year-old laptop I found in a dumpster, the laptop fits into a backpack just fine, and I don't need to charge the battery because it's so old the battery is long dead. When I want to use it, I plug into a wall socket at the public library. You see, portable electronic devices don't really need batteries at all.

But if you had a working battery, you could use that sweet Comcast Xfinity Wi-Fi.

The library has free bathrooms where I can bathe in the toilet.
