December 26, 2014, the US electric carmaker Tesla released an updated version of the discontinued two years ago, the first generation model Roadster, the mileage of 644 km, 60% higher than the original.   Advances in battery technology to enhance the performance of the Tesla product, after Roadster Mileage is 393 km. Tesla CEO Musk said Tesla high-performance graphene battery, compared to the current capacity increase of nearly 70 percent. British scientists have invented graphene after 10 years, the application of the battery with great breakthrough. In early December, the Western media reported that Spain and the Spanish company Graphenano Cordoba University to develop graphene battery, a charging time of just eight minutes, can travel 1000 km. It is graphene researchers called "super cell." "We still understand the situation, the specific situation in Spain is proving such a battery, if this is confirmed, it is indeed a revolutionary c

When fuel and air burn inside the cylinder of an internal-combustion engine, the energy being released comes from the electronic bonds that bind atoms together to form molecules. The bond energy of unburned hydrocarbon fuel and diatomic oxygen from the air is higher than that of the products of complete combustion, which are water and carbon dioxide. Upon combustion, this energy difference appears (mainly) as heat. This heat raises the pressure of the gases in the cylinder, driving the piston downward to turn the engine’s crankshaft. The very same kind of electronic bond energy stores and delivers the power we take from batteries. A battery at its simplest consists of a positive and a negative electrode, exposed to an electrolyte. In the case of today’s powerful Lithium-ion batteries , the electrolyte consists of Lithium salts dissolved in an organic liquid. Just as table salt—sodium chloride or NaCl—separates into oppositely charged sodium and chlorine ions when dissolve

Future Batteries: Lithium-Sulfur with a Graphene Wrapper

What do you get when you wrap a thin sheet of the “wonder material” graphene around a novel multifunctional sulfur electrode that combines an energy storage unit and electron/ion transfer networks? An extremely promising electrode structure design for rechargeable lithium-sulfur batteries, according to a paper published in APL Materials . Lithium-sulfur batteries are of great commercial interest because they boast theoretical specific energy densities considerably greater than those of their already well-established cousin, lithium ion batteries. A team of researchers led by Dr. Vasant Kumar at the University of Cambridge and Professor Renjie Chen at the Beijing Institute of Technology describe their design of a multifunctional sulfur cathode at the nanolevel to address performance-related issues such as low efficiency and capacity degradation. Metal organic frameworks (MOFs) have attracted plenty of attention recently, thanks to wide-ranging applications i

No negative lithium battery concept has born many years, but battery tech tree but felt no slow points, but the rechargeable lithium-ion battery technology stagnated. The far left no negative battery lithium battery, the battery capacity with three for 2Ah Recently, a Massachusetts company SolidEnergy Systems, said the new developed a "no negative lithium batteries ", using an ultra-thin to almost no metal anode and electrolyte safer, mobile phone battery life and electric vehicle charging problem get a great solution. At present, this battery has passed the United States the authority of an independent testing laboratory A123's battery tests, the prototype of the energy density of 1337 watts per liter (Wh / L), Tesla is currently twice the energy density of the battery. Its project leader, Bill Gates has won the support of MIT professor Donald Sadoway said that the current focus on the development of a new generation of SolidEnergy anode materials, can match with
