Researchers at MIT have developed a cathode, the negatively-charged part of an EV lithium-ion battery, using "small organic molecules instead of cobalt," reports Hannah Northey for Energy Wire.The organic material, "would be used in an EV and cycled thousands of times throughout the car''s lifespan, thereby reducing the carbon footprint …
Battery-powered thermostats require regular battery replacements, which can add up over time. Additionally, if the batteries run out, the thermostat will stop working, which can be inconvenient and may lead to increased energy costs. Hardwired thermostats, on the other hand, do not require battery replacements and are less likely to malfunction.
