Remember the Tesla batteries that could take your house off the grid? Now, Tesla’s back with more

In March, we were telling you about Tesla Motors’ new development, a new battery that could take your home off the grid and eliminate one of the major problems associated with renewable energy – storing it. Now, Tesla is already rolling out the new generation with some remarkable feature. The coolest one? Liquid cooling!

Samsung almost doubled the capacity of lithium-ion batteries by adding graphene

In a recent paper published in Nature, researchers at the Samsung Advanced Institute of Technology report how they nearly doubled the charge carrying capability of a lithium-ion battery by coating the silicon anodes with graphene. Paired with recent advances in graphene deposition and manufacturing, this sort of tech of could very well end up powering your notebook or phone a couple years from now.

Mercedes’ own response to Tesla’s home battery

Daimler, the giant auto maker from Germany, is releasing its own version of a large-storage battery on the heel’s of Tesla’s heralded Powerwall. Branded under Mercedes-Benz, the battery pack is destined for both automobiles and home use. So far, a 2.5 kWh each version has been made public, with Deimler claiming it can be packaged in up to eight modules bringing the total capacity to 20kWh worth of energy – more than enough to power a typical home or even a small business.

This new $2.50 device extends disposable battery life by 800% – will hit the market in September

A simple, cheap device could extend disposable battery life eight-fold; it suits all batteries from AAA to D and it works by keeping its voltage boosted to just above what most appliances consider ‘dead’. The technology was developed by US-based start-up, Batteroo and it’s called a ‘Batteriser’. It basically comprises of a very thin stainless steel sleeve (0.1 mm) that you can clip onto any

Soft, squishy and powerful: The Royal Institute of Technology creates batteries from trees

A team of researchers from the KTH Royal Institute of Technology and Stanford University has developed a method for making elastic, shock-resistant, high-capacity batteries from wood pulp.

What an overheated Lithium-ion battery looks like, inside and out

Lithium-ion batteries have pervaded most mobile technologies, including phones, notebooks or electric vehicles. Scientists involved in lithium-ion batteries are mainly interested in increasing the energy density so they can last longer and accelerating the charging time, but also avoiding failures. You can watch on YouTube a myriad of such fails, like batteries exploding and such. Thankfully, these events are particularly rare, yet they signal there’s still much room for improvement. University College London researchers were interested in studying how lithium-ion batteries perform under a certain kind of stress resulting from overheating, and recorded the first thermal failure using thermal imaging and non-invasive high speed imaging techniques to observe the internal structure. This way, they recorded both what happens outside and inside the battery when it overheats.

New Aluminum-ion battery fully charges in under a minute – 100 times faster than your laptop

Renewable energy and electric vehicles not only need high density storage mediums to become successful, but ones that can be replenished fast as well. A new battery, very similar to the popular lithium-ion variety used to power your smartphone, charges in under a minute and still works perfectly after 7000 cycles. Moreover, the battery is based on aluminium making it both easier and cheaper to manufacture.

IBM develops device which could power slums with used laptop batteries

An IBM team analyzed a sample of discarded batteries and found that they can still be used and can still provide benefits. They developed a device which uses re-usable Lithium Ion cells from discarded laptop battery packs to power low energy DC devices. They found that 70% of used batteries could still store enough power to keep an LED light on more than

This new battery can fully charge your smartphone in 30 seconds

An Israeli company has developed a battery that can charge a smartphone in just 30 seconds; to make things even more interesting, the technology could be scaled and power up electric cars in a matter of minutes.

Nuclear battery that uses water-based solution lasts longer and is more efficient

Though betavoltaics – battery technology that employs radiation as a means of power generation – has been around since the 1950s, developments thus far haven’t been the most promising. This may set to change after researchers at University of Missouri reported they’ve devised a nuclear-assisted battery, which works in a watery environment, that both lasts longer and is more efficient. The
