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

Packing peanuts could be reused in better batteries

When a new lab was recently being set up at Purdue University in Indiana, a lot of the equipment arrived in boxes full of protective packing "peanuts." Unfortunately, few facilities exist for recycling the little pieces of foam, so they typically end up sitting in (or getting blown around) landfills for several decades. A team of Purdue researchers, however, discovered that they could find use in better-performing lithium-ion batteries. Read More

Silk-derived material could boost battery performance

Next-generation lithium-ion batteries may hold more charge for a greater number of cycles thanks to a new material derived from natural silk. Scientists at the Beijing Institute of Technology found that not only does their regenerated silk fibroin material work for over 10,000 cycles but it also stores five times more lithium than graphite, which is the most common choice for the anode (negative electrode) in lithium-ion batteries.Read More
