This battery combines two promising types of battery sub-fields – solid-state electrolytes, and all-silicon odes – into one compact unit. This new battery is extremely versatile and safe. Science will publish the science in the September 24th issue. The research was led jointly by UC San Diego researchers and LG Energy Solution researchers.
Stretchable fuel cells
A new invention called stretchable fuel batteries could solve all of your battery problems. It uses human sweat to extract energy that can be used for powering Bluetooth radios and LEDs. Researchers developed a biofuel cells with flexible membranes that can be attached to custom-made circuit boards. This could be used for stationary cycling to power an LED. According to the researchers, stretchable fuel cells are an important advancement in battery technology because it could enable wearable electronics to be powered from the human body.
Nanogenerators
A team of researchers at Georgia Tech has developed a battery innovation called a nanogenerator. To generate electricity, the new technology uses a technique called the triboelectric phenomenon. This happens when two surfaces rub into each other creating friction that transfer electrons from one to the next. This causes the surface receiving electrons to become negatively charged while the opposite surface becomes positively charged. This causes static electricity. However, unlike an external circuit it doesn't travel in an open circuit. You can observe the triboelectric effects by placing a balloon on the head of someone you care about.

How To
How to diagnose your vehicle properly for repair
To determine if your car needs repairs, you should first look at the symptoms that your car presents. Follow these steps to properly diagnose your vehicle.
-
Check engine lights. Inspect the dashboard light indicators. These include the engine lights, the oil pressure gauge and the battery light indicators. The RPM gauge and coolant temperature gauge should also be checked. If they have been flashing for more days than usual, it could be a sign that something is wrong with the vehicle.
-
Take a look at the treads. Tires with worn treads could cause problems when handling or braking. It is also important to inspect the wheel treads. They should look clean and be smooth. You can do this by taking off the wheels. A flashlight can be used to check how worn the treads are.
-
Check the level of brake fluid. You must keep track on the level of brake fluid in your vehicle. This ensures that your brakes work properly. Low brake fluid levels could cause your brakes to fail when you apply pressure.
-
Test the suspension system. Most vehicles have a suspension system that absorbs shocks and vibrations. It improves control and allows for smoother accelerations or decelerations. You might notice a wobbly feeling or uncontrollable shaking in your vehicle if it has a problem with its suspension. To determine whether your vehicle may have a suspension issue, you can try to put weight on the rear or front axle and watch the movement.
-
Examine your steering column. The steering column connects the steering wheel to all other components of the vehicle. Many accidents can cause damage to steering columns. If yours feels loose or shaky, you should replace it.
