India's Battle Against Air Pollution

Historically, India has faced challenges with persistent air pollution as a result of industrial development. One key approach to combat this has been to reduce greenhouse gas emissions. For example, Indian policymakers have been pushing for the commercialization of electric vehicles which has unlocked various incentives for companies like Vision Mechatronics to develop electric vehicles run by lithium-ion batteries.

How Lithium-Ion Batteries Power EVs

India “seeks to attain a 30% share of electric vehicles, in the total vehicles sold, by 2030” and accelerating the market for it by “moving from incentives to mandates” like a Zero Emission Vehicle policy (NITI Aayog). Taking advantage of this political support, Vision Mechatronics “aims to develop a complete domestic ecosystem around EVs” which have “zero tailpipe emissions” (Vision Mechatronics).

Many electric vehicles are driven by lithium ion batteries which “can contain hundreds of individual cylindrical battery cells that are the same shape as common AA and AAA batteries” (Edmunds). They are extremely energy efficient and can store a multitude of energy; on full battery, electric cars powered by lithium-ion batteries can drive over 200 miles–although it may depend on the specific car model. Compared to their precursor, lead-acid batteries, lithium-ion batteries have higher energy density which increases the mileage of a car. They are also extremely lightweight and this ensures that EVs aren’t too heavy. Moreover, the electricity used to refuel the EVs come from renewable energy sources like solar power.

The Environmental Cost of Battery Production

There are various concerns that lithium-ion battery powered cars take a long time to charge. Although this may be true for some models, recent developments have led to an increase in charging efficiency and overall energy storage. For instance, the Hyundai Ioniq 5 can be charged “from 10% to 80% in just 18 minutes” (Edmunds).

Moreover, the environmental impact that the creation of lithium-ion batteries has is detrimental as “the mining process for lithium and other materials used in these batteries can… lead to water pollution and habitat destruction” (Tara Electronics). Although this is the undeniable truth, it is promising to know that due to advancements in technology it has been shown that electric car batteries can “last 12 to 15 years in moderate climates”, meaning that they don’t have short lifespans (Edmunds). Moreover, “instead of ending up in a scrapyard like most internal combustion engines do, electric vehicle batteries can be repurposed, refurbished, or recycled when they fail” (Edmunds).

Building India's EV Ecosystem

Gupta believes that local battery production in India can help India progress towards an economy that is powered by clean energy. She mentions that it has been difficult to employ skilled labor in this field due to geopolitical tensions and a lack of awareness regarding the importance of this field. However, she is trying to bridge this gap by making opportunities in her company as accessible to the next generation as possible.
