Organic cathode for high performance batteries

Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have designed a new, organic cathode material for lithium batteries. With sulfur at its core, the material is more energy-dense, cost-effective, and environmentally friendly than traditional cathode materials in lithium batteries. The research was published in Advanced Energy Materials on April 10, 2019. Optimizing cathode materials…

Solid-state batteries – a new battery design that uses all solid components

But building a long-lasting solid-state battery is easier said than done. Now, researchers at the Georgia Institute of Technology have used X-ray computed tomography (CT) to visualize in real time how cracks form near the edges of the interfaces between materials in the batteries. The findings could help researchers find ways to improve the energy…

RCPROPLUS Pro-D6 Supra-X

  Pro-D6 P8 Supra X battery connectors are a great choice for high-current and voltage requirement, offering a wide (low-resistance) surface area for max efficient power transfer. The 24K gold-plated bullet plugs are assembly stress-free, whilst the casing with a design which eliminates separation uses high temperature capable impact-resistant plastic made in Japan. Specifications:  Continuous discharge current: 190A…

The electric drive is the future!

The electric drive is the future – because electricity is renewable! The use of renewable energy in the construction of the electric car reduces the CO2 backpack significantly. The noise pollution in our cities would fall dramatically. Anyone who has ever lived on a major road knows how stressful and ultimately pathogen is traffic noise….

The remarkable story of Tesla’s partner, Panasonic

Tesla’s battery partner and long-time supporter, Panasonic, just turned 100 years old. Entrepreneur’s Lydia Belanger reports that throughout the last century, “Panasonic has pivoted regularly, expanded globally and today continues to look toward the future of technology, including teaming up with Tesla.” Panasonic’s financial investments in Tesla aren’t the only support it provides — its…

Resistance Spot Welding (RSW)

Series Welding – RSW utilizes two electrodes positioned adjacent to each other but separated by an air gap or other dielectrics. Each electrode contacts the same surface of the base material. This type of welding is utilized where access to both sides of the weld joint is physically restricted or if a component damage would result if the…

Batteries – Comparing the specific energy of various electrochemistry

  The specific energy density of battery cells, depending on chemistry: Lead Acid (PbSO4 ) = 40Wh/kg NiCd (Nickel Cadmium / NiOOH) = 60 Wh/kg NiMh (Nickel Metal Hydride / NiOOH) = 90Wh/kg LTO (Lithium Titanium Oxide / Li4Ti5O12) = 80Wh/kg. LPF (Lithium Iron Phosphate / LiFePO4) = 115 Wh/kg. LMO (Lithium Ion Manganese Oxide / LiMn2O4)…

Back in time – A Bit About Batteries, with Martin Eberhard

November 30, 2006 By now most people know that the Tesla Roadster is powered by Lithium-ion (Li-ion) batteries. But here are a few things about our batteries you might not have heard. Our battery system – or Energy Storage System, as we like to call it – is comprised of 6,831 individual Li-ion cells. It’s roughly…

Inside Panasonic NCR18650 Lithium-Ion battery cell

Cristian Miuta, Jan 30, 2018. The metal case holds a long spiral comprising three thin sheets pressed together: a positive electrode, a negative electrode, and separator. Inside the metal case, these sheets are submerged in an organic solvent that acts as the electrolyte – Ethylene Carbonate, Diethyl Carbonate and Lithium Hexafluorophosphate (salt).   The separator…
