xMEMS aims for mobile audiophiles with silicon-based microspeakers

xMEMS Labs out of Santa Clara, California, is aiming to replace century-old coil-based speaker technology with silicon-based microspeakers, and has launched three Solid-State Fidelity solutions for use in upcoming true-wireless earphones, in-ear monito… Continue reading xMEMS aims for mobile audiophiles with silicon-based microspeakers

Solid-state refrigerant works under pressure for greener cooling

As useful as refrigerators and air conditioners are, the gases they use as refrigerants can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a … Continue reading Solid-state refrigerant works under pressure for greener cooling

The State of Play In Solid State Batteries

Electric vehicles are slowly but surely snatching market share from their combustion-engined forbearers. However, range and charging speed remain major sticking points for customers, and are a prime selling point …read more Continue reading The State of Play In Solid State Batteries

Liquid salt greases wheels of high-density lithium metal battery design

Scientists at Japan’s Tokyo Metropolitan University have taken aim at a common problem plaguing next-generation lithium metal batteries, finding a promising solution in a salty liquid that reduces problematic resistance between key components. The resu… Continue reading Liquid salt greases wheels of high-density lithium metal battery design

Rubbery electrolyte makes for longer-lasting, safer EV batteries

Famously an insulator, rubber might not seem like a great candidate for an electrolyte material in a battery, but researchers at Georgia Tech have developed a new rubbery material with a high conductivity. This elastomer electrolyte could make for safe… Continue reading Rubbery electrolyte makes for longer-lasting, safer EV batteries

Electrochemical pulses address weakness in next-gen lithium metal batteries

Two promising avenues in the development of next-energy storage involve the use of high-density lithium metal and an electrolyte that is solid rather than liquid, and a new study brings these branches of battery research together in an exciting new bre… Continue reading Electrochemical pulses address weakness in next-gen lithium metal batteries

Organic-based EV battery turns to ethanol for a boost in energy density

While on the face of it, the lithium-batteries that power electric vehicles play an important role in our ongoing shift to sustainable transport, they aren’t without environmental problems of their own. Batteries that use organic, readily available mat… Continue reading Organic-based EV battery turns to ethanol for a boost in energy density

Sandwich-style battery could charge EVs in as little as 10 minutes

Scientists at Harvard University have come up with a promising new design for an experimental battery, one which they say could lead to electric cars that charge in as little as 10 minutes. The alternative architecture is also claimed to offer a far lo… Continue reading Sandwich-style battery could charge EVs in as little as 10 minutes
