Smart chip offers a warning ahead of battery failure

The lithium-ion batteries that power everything from smartphones to electric vehicles carry a relatively low individual chance of failure, but the sheer quantity in use everyday means the risk of something going horribly wrong somewhere in the world is quite real. Looking to safeguard against such events, a team of scientists has developed a smart chip that can be embedded inside these batteries to monitor their health, offering a warning when it is at risk of catching fire or exploding.Read More

New silicon-based anode set to boost lifetime and capacity of lithium-ion batteries

A new approach developed by researchers at the University of Waterloo could hold the key to greatly improving the performance of commercial lithium-ion batteries. The scientists have developed a new type of silicon anode that would be used in place of a conventional graphite anode, which they claim will lead to smaller, lighter and longer-lasting batteries for everything from personal devices to electric vehicles.Read More

Candle soot could reduce lithium ion battery production costs

A new study suggests that the carbon-based waste material given off by burning candles could be suitable for use in larger, more powerful lithium ion batteries such as those used in electric cars. Two researchers from the Indian Institute of Technology found that as an anode material, candle soot compares favorably to existing commercial options because of its low cost of production and fractal-like nanoparticle structure.Read More

Portobella mushrooms improve battery recipe

The number of electric vehicles and mobile devices is expected to surge over the coming decade, which would place considerable strain on our environment and resources as far as battery technology currently stands. In an effort to find more sustainable alternatives for battery materials, researchers from the University of California, Riverside have created a battery incorporating the skins of portabella mushrooms. The move not only has the potential to reduce the economic and environmental cost of battery production, but may also result in batteries whose capacity increases over time.

Aluminum "yolk" nanoparticles deliver high-capacity battery recipe

Researchers at MIT and Tsinghua University in China have found a way to more than triple the capacity of the anodes, or negative electrodes, of lithium-ion batteries while also extending their lifetime and potentially allowing for faster battery charging and discharging. The new electrode, which makes use of aluminum/titanium "yolk-and-shell" nanoparticles, is reportedly simple to manufacture and is especially promising for high-power applications.Read More

Additives keep lithium-ion batteries from catching fire

Processor chips may get all the glory, but if it wasn't for lithium-ion batteries, modern electronics would look like something out of the 1950s. Unfortunately, while they may be compact and long lasting, these batteries also suffer from overheating and can become fire hazards as they get old. Now a team led by Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory has come up with an additive that holds the promise of extending lithium battery life while improving safety and performance.Read More

Tesla unveils battery storage system for home, business and utility use

The Tesla home battery system hinted at by CEO Elon Musk several months ago has finally been unveiled by Musk himself at the company’s design studio in Hawthorne, California. Dubbed the Powerwall, the stationary home battery offers 10 kWh of storage capacity for the relatively modest price of US$3,500. A smaller unit is also available at 7 kWh for $3,000, and homeowners can stack multiple units if needed. Read More

Gogoro's battery-swapping Smartscooter ready to roll in Taiwan

Taiwan-based startup Gogoro drew plenty of attention when it unveiled its Smartscooter at CES earlier this year. The thinking is that these electric two-wheelers will be ridden around urban centers and their lithium-ion batteries switched over at exchanges when they run out of juice. The idea is now one step closer to reality, with the announcement of a pilot program in Taiwan ahead of a launch this coming summer. Read More
