Engadget reports on research into battery longevity at UC Irvine that could result in batteries lasting significantly longer than current Lithium batteries.
The Engadget article states that the researchers, “…coated the gold nanowire they were using in manganese dioxide and swapped the lithium for electrolyte gel. The gel and oxide fused into a protective sheath around the wire, and voila: the experimental battery completed hundreds of thousands of cycles over a period of three months with no detectable degradation.”
MIT Technology Review details a new approach to battery making that could utilise carbon dioxide from the air for conversion into carbon nanotubes to be used in high-performance battery production. The research – a collaboration between George Washington University and Vanderbilt University – could both reduce the costs of creating carbon nanotubes and play a part in battling climate change. From the article:
“Capturing and sequestering carbon dioxide is expensive and unproven at the scale needed to significantly reduce emissions. The deployment of carbon capture and storage (CCS) technology is well behind schedule if it is to play the role that the governments behind the recent Paris climate agreement are betting it can play. In the absence of climate policies like a cap-and-trade system or carbon tax, the economics just don’t work.”
“That might change if the gas could be turned into a valuable product. Researchers have previously devised methods for using carbon dioxide to make liquid fuels like methanol, but those products have been relatively low-value commodities. Given the cost of today’s batteries, the new method makes a kilogram of carbon dioxide six times more valuable than one that is converted into methanol, says Stuart Licht, a professor of chemistry at George Washington.”
“Replacing commonly used graphite anodes with carbon nanotubes can boost the storage capacity of advanced batteries. In proof-of-concept lab tests, Licht and his colleagues showed that nanotubes made with their process gave a small boost to the capacity of small lithium-ion batteries and almost quadrupled the capacity of sodium-ion batteries, an emerging energy storage technology.”
Inhabitat reports that Energizer has launched the first rechargeable batteries made from recycled batteries, including those from hybrid cars and small electronic devices. Energizer aims to include 40% recycled material in it’s batteries by 2025, although for now it’s only around 4%. But it is a start.
Microsoft researchers test combinations of different battery types, managed by software, to improve endurance, efficiency and performance.
Per MIT Technology Review:
“Microsoft researchers show that batteries that can be more actively managed by software might make our devices last longer.”
Cleantechnica highlights the world’s first all- electric, emission-free ferry. Combining the use of lighter materials and hydro-power to recharge the batteries, the Ampere is the first all-electric battery-powered car and passenger ferry in the world.
FastCoExist highlights a Kickstarter project that fits with the trend of carrying spare / backup batteries for gadgets. The difference here though is that the device – called the Better RE – allows you to repurpose / upcycle old batteries.
Techcrunch reports on new battery technology from Nucleus Scientific that could see electronic devices charged in a few minutes rather than hours. The company has been working for 8 years on the technology that they believe can power the next generation of electronics and even cars such as a Tesla by using new techniques for storage and transfer of energy.
Inhabitat and many other sites reports on Tesla’s new product – the Powerwall battery that stores energy from solar panels or wind turbines and then releases it as required.
PC World reports on research into fast-charging batteries: by using aluminium and graphite, the batteries could charge in as little in a minute and last thousands of cycles.
