This metal case holds a long spiral comprising three thin sheets pressed together: A Positive electrode A Negative electrode A separator Inside the case these sheets are submerged in an organic solvent that acts as the electrolyte. Ether is one common solvent. The separator is a very thin sheet of microperforated plastic. As the name implies, it separates the positive and negative electrodes while allowing ions to pass through. The positive electrode is made of Lithium cobalt oxide, or LiCoO2. The negative electrode is made of carbon. When the battery charges, ions of lithium move through the electrolyte from the positive electrode to the negative electrode and attach to the carbon. During discharge, the lithium ions move back to the LiCoO2 from the carbon. The movement of these lithium ions happens at a fairly high voltage, so each cell produces 3.7 volts. This is much higher than the 1.5 volts typical of a normal AA alkaline cell that you buy at the supermarket and helps make lithium-ion batteries more compact in small devices like cell phones. See How Batteries Work for details on different battery chemistries. We'll look at how to prolong the life of a lithium-ion battery and explore why they can explode next

Pune Municipal Corporation (PMC) plans to set up 500 EV charging stations

  Pune Municipal Corporation (PMC) plans to set up 500 EV charging stations in the public areas of the city. PMC has also selected locations for the set up of charging stations which includes municipal gardens, educational institutes, and main roads. PMC has issued tender for the same and private agencies too can bid on the setup. It plans to charge a minimal fee for charging vehicles and the amount earned will be used to maintain the stations. The implementation of the project will take place on a revenue-sharing basis. PMC will provide the required space for private owners to establish the stations and other arrangements can be made by the companies. Setting up new EV charging stations will boost the adoption of electric vehicles in the city of Pune. In Pune and Pimpri Chinchwad, people are buying more electric vehicles than electric rickshaws, and hence e-rickshaws couldn’t make an impression in the city. But officials believe that e-rickshaws have a brig...

Electric vehicle charging per kilometre 60 paise

  The Ministry of Power has previously announced new EV charging infrastructure standards and guidelines. In compliance with the rules, the state government has fixed the ceiling cost of service charges to be charged by electric vehicle public charging stations. It approved the Rs 12.06 + applicable GST service cost maximum for electric vehicle rates covered by State/Central subsidies. it is still less expensive than petrol and diesel. “It costs Rs 300 if any four-wheeler takes 25 units to completely charge their cars.” “You can’t even get three litres of petrol with the same quantity of petrol,” Car comparison between petrol, diesel and electric vehicles If the price of petrol is considered at Rs 100 per litre and mileage is considered 16 km per litre, the cost of the car, per kilometre, will be about Rs 6.25. If the price of diesel is considered at Rs 95 per litre and mileage is considered 22 km per litre, the cost of the car, per kilometre, will be around Rs 4.31.  ...

Lithium battery business training

  Some dramatically different approaches to EV batteries could see progress in 2023, though they will likely take longer to make a commercial impact. One advance to keep an eye on this year is in so-called solid-state batteries. Lithium-ion batteries and related chemistries use a liquid electrolyte that shuttles charge around; solid-state batteries replace this liquid with ceramics or other solid materials.  At the same time, concerns about supplies of key battery materials like cobalt and lithium are pushing a search for alternatives to the standard lithium-ion chemistry.  In the midst of the soaring demand for EVs and renewable power and an explosion in battery development, one thing is certain: batteries will play a key role in the transition to renewable energy. Here’s what to expect in 2023. The global battery value chain, like others within industrial manufacturing, faces significant environmental, social, and governance (ESG) challenges Environmental:  The ex...
