Kyoto team develops new cathode material for high-energy-density rechargeable magnesium batteries

Green Car Congress

A team of researchers from Kyoto University has demonstrated ion-exchanged MgFeSiO 4 as a feasible cathode material for use in high-energy-density rechargeable magnesium batteries. Moreover, the terrestrial abundance and melting point of elemental magnesium by far surpass that of lithium, translating to a cheap and safe battery system.

Stuff We Use: Under Pressure (Washers)

The Truth About Cars

For ages, this writer used a gasoline-powered pressure washer, firm in the belief it ran better and more reliably than any cheap electric plug-in unit ever would. It is estimated recharging takes about twice as long as discharging, though I tend to just simply plug the thing in overnight; it’s always full the next time it is needed.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

It occurred in the wake of the California electricity crisis of 2000 and 2001, when mismanaged deregulation, market manipulation, and environmental catastrophe combined to unhinge the power grid. And EV owners would become entrepreneurs, selling electricity back to the grid. AC Propulsion’s experiment was timely.

EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think!

Plug In India

Rechargeable sodium-ion batteries are similar in construction to lithium-ion ones. Read the C&EN research here Lithium right now is very expensive and Sodium is quite cheap. The cycle life is crazy, as you can see here they claim more than a lakh cycles on their cell, while LFP cells have around 2000 cycles.

The difference between lithium iron phosphate and lithium battery

Setec Powerr

Lithium iron phosphate batteries have a long life and cycle life of more than 2000 times. Lithium iron phosphate batteries are green, non-toxic, non-polluting, raw materials from a wide range of sources, and cheap. Lithium cobaltate is currently the majority of lithium-ion battery cathode material. The use of safe. Scope of use.

Why Warren Buffett is investing in electric car company BYD - Apr. 13, 2009

Tony Karrer Delicious EVdriven

A chemist and government researcher, Wang raised some $300,000 from relatives, rented about 2,000 square meters of space, and set out to manufacture rechargeable batteries to compete with imports from Sony and Sanyo. By about 2000, BYD had become one of the worlds largest manufacturers of cellphone batteries.
