Lithium-ion batteries are commonly used in many electrical devices, but global lithium resources are rapidly declining and mining operations create a large carbon footprint. Sodium-ion batteries could offer a sustainable alternative which, if optimised, could be used in electric vehicles. … Continue reading →

From Pencil Lead to Diamond This structure makes the material very soft and it can be used in products such as pencil lead. In diamond, on the other hand, the carbon atoms are strongly bonded in all directions; thus diamond … Continue reading →

XPeng Motors then received a renewed Autonomous Vehicles Testing Permit from the California Department of Motor Vehicles in March 2020. XPeng started production of its first model, the XPeng G3 SUV, in November 2018. It launched the G3 in December … Continue reading →

Graphene has a much higher electrical conductivity and charges transfer mechanisms that lend it to being an effective medium for electronics. There are several unique benefits where graphene can be used, and silicon cannot. What will replace silicon in solar … Continue reading →

Graphene is the super substance that could replace silicon, plastic and glass. The silicon, plastic, and glass that make up much of our tech these days could soon be replaced with something old, yet completely new: Graphene. What will graphene … Continue reading →

After its European debut in Norway, the Chinese electric car manufacturer Xpeng also plans to launch in Sweden, Denmark and the Netherlands next year. It is not yet known when Xpeng also plans to come to the UK or the … Continue reading →

Tesla’s vision to produce and deliver the base Model 3 at $35,000, which is within the reach of most consumers and the fact that the cost per mile will be negligible will play a significant part in their decision to … Continue reading →

Tesla’s work in an oligopoly market which have a limited competition in which a few producers control the majority of the market share and typically produce homogenous products. What is Tesla industry? About Tesla Inc The Company’s segments include automotive, … Continue reading →

Since the unveiling, Tesla has been producing the 4680 cells at a “pilot production facility” in Fremont and deploying large-scale production at other factories, including Gigafactory Texas and Gigafactory Berlin. Which Tesla will get the 4680 battery? Model YWith 4680 … Continue reading →

Electric Currents in Batteries We learned Ohm’s law, which told us that electric current flows from a positive to a negative electric potential while the electrons move in the opposite direction. Kirchhoff’s law taught us that there must be continuity … Continue reading →

Recharging a battery involves the conversion of electrical energy to chemical energy. During recharging, there is movement of electrons from an external power source to the anode, and on the other side electrons are removed from the cathode. Can batteries … Continue reading →

Recommended constructions for bullet resistance are 8 in. (203 mm) solid or grouted concrete masonry walls or 12 in. (305 mm) hollow units with sand- filled cores. Will a concrete block stop a bullet? Most household objects won’t reliably stop … Continue reading →

A human brain’s probable processing power is around 100 teraflops, roughly 100 trillion calculations per second, according to Hans Morvec, principal research scientist at the Robotics Institute of Carnegie Mellon University. Is the human brain more powerful than a supercomputer? … Continue reading →

Mapping out every intersection, sign, and signal Then, instead of relying solely on external data such as GPS which can lose signal strength, the Waymo Driver uses these highly detailed custom maps, matched with real-time sensor data, to determine its … Continue reading →

But even if the battery pack doesn’t set your car on fire, it’s still a bad idea to keep it inside the car because heat will degrade Li-Ion cells. If you store a fully charged battery at high temperatures, that’s … Continue reading →
