Lithium-ion Batteries to be Used in India’s Electric Vehicles

Lithium-ion Batteries

 ISRO Satellite

ISRO Satellite is India’s 3rd Communication Satellite to Launch successfully on orbit. The space agency of Indian Government is at Bengaluru from where operations are directed.

LITHIUM-ion BATTERY IN INDIA

The ambitious Battery vehicles from Central Government project based on Indian Space Research Organisation (ISRO) by using mercantile Lithium-ion Battery devices developed by scientific technology. In case, if there is any sudden malfunction or fault in battery makers had to pay a penalty of Rs.1 crore immediately as a technology transfer fee to ISRO.

The 10-15% prices of e-vehicles are possible to economize by the commercialisation of ISRO’s technology. Few experts opined that the e-vehicle technology is in still build out and the price is significantly in peak. Apart from this, the ecosystem of the e-vehicles will not organize. Charging stations are not yet in sites, as the price of the battery is not reasonable, the users have the cost and resilience issues.

MANUFACTURE OF LITHIUM-ion BATTERY

The positive and negative electrodes and electrolyte are the three chief functional constituents of lithium-ion battery. Usually, the positive electrode is a metal oxide and the negative electrode is made of carbon material. The electrolyte is a lithium salt in an organic solvent.  The electrochemical tasks of the electrodes alter between anode and cathode, based on the regulation of the current flow through the cell.

The most profit-oriented negative electrodes are graphite. A positive electrode is basically one of the material layered oxide i.e., lithium cobalt oxide, a polyanion i.e., lithium iron phosphate or a spinel i.e., lithium manganese oxide. A short time ago, graphene formed electrodes (such as 2D and 3D structures of graphene) have also cast off as electrodes for lithium batteries.

The electrolyte is usually a combination of organic carbonates like diethyl carbonate/ethylene carbonate in the presence of lithium ions. Generally, the non-coordinating anions salts like LiPF6, LiAsF6, LiClO4, LiBF4, LiCF3SO3 are used as non-aqueous electrolytes.

The voltage and energy density and viability and safety of Li-ion battery change greatly based on the type of material used. Lithium-ion batteries are not so affordable than Ni-Cd batteries and work at wider temperature by consuming higher energy. To control the peak-voltage they require a protective circuit.

E-vehicles, in sight of their price, will have effective action only in public transport buses, cabs/taxis three-wheelers. “Creating demand over e-vehicles is essential,” the experts said. ISRO and BHEL are trying to develop low-price lithium-ion batteries for electric vehicles.
