Elon Musk's Big Battery 50% complete

Tesla boss said the project is a great example of how to replace fossil fuels with renewables.

The battery to be made in South Africa, will be paired to a neighbouring wind farm run by renewable energy company Neoen in Hornsdale to bring added reliability and stability to the state’s power supplies. It is thought to be costing taxpayers about $50m and forms part of the state government’s $550m energy plan. Other elements of the energy plan include installing emergency generators at two sites in Adelaide, a push for more gas-fired power generation and a solar-thermal power plant near Port Augusta. It was prompted by a series of power problems, including a statewide blackout when a freak storm brought down transmission lines a year ago and another event last summer when heavy demand and a lack of electricity flowing through the interconnector with Victoria cut services to thousands of properties.

MotoGP set for all-electric class in 2019

The worlds most popular motorcycle racing event is now adding an all electric class.

Dorna CEO, Carmelo Ezpeleta, told that an electric support series featuring up to 18 bikes could start competing as early as 2019. Plans are under way to have an electric series on the support bill for as many as five MotoGP races in 2019, with four manufacturers having offered to supply the grid of 18 bikes. The bikes are expected to reach speeds of around 200 km/h (124mph), making them slightly slower than the existing Moto3 bikes, while races are planned to last around 10 laps each. Electric motorcycles have been around long enough that the MotoGP class won’t be the first time they’ve seen serious competition. What started in 2010 as a zero-emissions class at the yearly Isle of Man TT motorcycle race is now dominated by electric bikes, and they’re quickly catching up to their gas-powered counterparts. Meanwhile in Australia the local superbike championship has run an eFXC electric Formula Xtreme class since 2011. While Formula E relies on carbon-neutral glycerine generators to recharge its cars between sessions, Ezpeleta wants the new MotoGP support series to use solar panels. “We want the batteries to be recharged from solar panels, not from generators like in other championships,” added Ezpeleta. “This way, we can leave something profitable for the circuits where the series races.”

Adding graphene girders to silicon electrodes could double the life of lithium ion batteries, huge potential within the automotive industry.

New research has found an effective approach to replacing graphite in the anodes of lithium-ion batteries using silicon, by reinforcing the anode's structure with graphene girders. This could more than double the life of rechargeable lithium-ion based batteries and also increase the capacity delivered by those batteries.

Elon Musk wants to break physics with his batteries!

Elon Musk knows how to make promises. Even by his own standards, the promises made last week while introducing two new Tesla vehicles—the heavy-duty Semi Truck and the speedy Roadster—are monuments of envelope pushing. To deliver, according to close observers of battery technology, Tesla would have to far exceed what is currently thought possible.

Engineers develop flexible lithium ion batteries that can be used for wearable electronics!

Engineering researchers have developed a prototype of a high-performance flexible lithium-ion battery that demonstrates -- concurrently -- both good flexibility and high energy density. The battery is shaped like the human spine and allows remarkable flexibility, high energy density, and stable voltage no matter how it is flexed or twisted. The device could help advance applications for wearable electronics.
