With the development of a new way to build and recycle vital lithium-ion batteries, GRST‘s solution offers a pathway to make the electric cars of the future even cleaner.

The electric vehicle market is growing fast and is projected to soar as governments and consumers move away from vehicles that run on planet-warming fossil fuels.

The International Energy Agency predicts there will be at least 125 million electric vehicles worldwide by 2030. Mass adoption will be essential if the world is to cut pollution in cities and meet its climate targets. Unsurprisingly, demand for batteries is expected to increase 30% each year until 2030.

A greater need for batteries to power more of these vehicles means increased demand for metals like lithium, a finite resource whose extraction has raised ecological and human rights issues. The lithium mining required to meet the demand takes a heavy toll. Trees are often cut down to make room for mines, while chemicals used in the process can poison waterways. In some countries, worker protections for miners are limited, raising human rights concerns. Meanwhile, millions of tonnes of batteries are expected to be decommissioned over the coming decades, creating hazardous waste.

Enter GRST, a cleaner, safer and cheaper way to make and recycle lithium-ion batteries.

GRST's Solution

Co-founded by Justin Hung, GRST (which stands for Green, Renewable, Sustainable Technology) has come up with a cleaner process to make batteries that pollutes less and uses components that can be more easily recycled. Instead of using toxic solvents and hard-to-recycle materials, GRST has created a way to build the battery using a water-soluble binding composite, so that at the end of the battery’s life, the lithium, cobalt and nickel can be more economically recovered and reused again in another battery, reducing demand for further extraction.

Their Impact

GRST’s method not only reduces greenhouse gas emissions from production by 40%, but also produces a battery that lasts up to 10% longer than average – characteristics that will accelerate the adoption of electric vehicles and enable more people to breathe cleaner air.

GRST batteries are already being sold in multiple countries. Following the recent completion of a new factory, GRST is ready to scale the battery technology. They are targeting a five percent share of the global green battery market by 2030 and aim to establish several circular supply chains over the next few years. GRST’s efforts are key to enabling the electric vehicle revolution to drive forward sustainably.
