Discarded Batteries Could Light Developing Regions

IBM researchers in India discovered that 70% of discarded laptop batteries have enough capacity to power an LED light bulb for 4 hours per day for a year. This is due to the fact that laptops lose their portability long before their batteries are completely dead (their battery life becomes unacceptably short), so they are […]

Queensland Researchers Develop Supercapacitor For EVs

Researchers at the Queensland University of Technology in Brisbane, Australia have developed a new carbon-based supercapacitor (otherwise known as ultracapacitor) film technology with an improved power density. This enables it to provide larger bursts of power for acceleration. This just means it can discharge its energy more quickly. According to the Queensland University of Technology’s website: […]

New Battery Tech Recharges In 2 Minutes And Lasts 20 Years

I’ve been monitoring and writing about battery technology advancements for years, and was let down so many times. This time, a li-ion battery technology that can be recharged to 70% in 2 minutes has been developed, and it can theoretically last 20 years! This technology is facilitated by the use of a titanium dioxide-based gel […]

Tesla Gigafactory Might Achieve $100/kWh Battery Cost

Electric vehicle battery technology is usually of the lithium-ion chemistry, and it costs $400 to $500 USD per kWh, down from $1,000 a few years ago. They have certainly made strides, and they are set to make even bigger strides in the near future, possibly to $100 per kWh of batteries. Tesla Motors has aimed […]

Advanced Utility-Scale Battery Capacity To Increase Significantly

Originally published on Cleantechnica By Nicholas Brown. The energy capacity (in this case, the deployment) of advanced utility-scale batteries is forecast to grow 71% annually according to a Navigant Research report titled Advanced Batteries for Utility-Scale Energy Storage. The report expects the industry to grow from a capacity of 412 MWh in 2014 to over 51,200 […]
