Lithium: The Fuel of the Green Revolution

The world is shifting greener.

And while people have always wanted electric cars and inexpensive solar power, the reality is that until recently, battery technology just wasn’t good enough to store energy on an economical or practical basis.

Things have changed, and the green revolution has been kickstarted by battery power. The commercialization of the lithium-ion battery has solved a crucial green energy problem for two major reasons that can be related back to the properties of lithium:

1) Lithium has extremely high electrochemical potential, and so do lithium-ion cells:

Battery cellTypical Voltage
Lithium-ion (Cobalt)3.6V
Lead Acid2.0V
NiMH1.2V
NiCd1.2V

This means one lithium-ion cell can do more – making it much more efficient to use in everything from electronics to energy storage.

2) Lithium is also the lightest metal on the periodic table. Batteries need to be as light as possible, especially in electric cars.

How Lithium Gets Used

2001
Many years ago, lithium was used chiefly for a variety of industrial purposes. Major sources of lithium demand included ceramics, glass, aluminum production, lubricants, and as a catalyst for rubber production.

2015
In modern times, with the commercialization of the lithium-ion, batteries are now the major source of demand for lithium at 39%.

2025
According to a report by Deutsche Bank, in 2025 the battery market for lithium alone will be more than 2x bigger than the total lithium market today.

About 70% of all lithium will go to electric vehicles, e-bikes, traditional batteries, and energy storage, making it the uncontested fuel of the green revolution.

Major Lithium Drivers

Lithium-ion battery demand is primarily driven by rapid growth in the electric vehicle market, which is expected to make up 35% of all vehicle demand by 2040.

But renewable energy storage also plays a role in driving lithium demand. With solar and wind energy being installed at a rapid pace, that means more batteries must be procured to store this energy. This can be done for a home system with a product like Tesla’s Powerwall 2.0, and it is being done on a utility scale as well.

Two Types of Lithium

Prices for lithium have skyrocketed in the last two years – and it is worth knowing the two different types of lithium used by the market.

Lithium carbonate:
This is the first chemical in the production chain, and as a result, sells for less than lithium hydroxide. It can be used as cathode material in some batteries, such as the Nissan Leaf, where it is used in a LMO with NMC formulation (Lithium manganese oxide / nickel manganese cobalt oxide chemistries)

Lithium hydroxide:
This is a by-product of lithium carbonate, created by a metathesis reaction with calcium hydroxide. It can be used to produce cathode material more efficiently and is actually necessary for some types of cathodes. It’s used in the Tesla Powerwall and Model S, for example.

Lithium Mining

There are two basic ways to extract lithium: from brine or from hard rock. The latter mainly consists of spodumene production.

Brine deposits represent about 66% of global lithium resources, and are found mainly in the salt flats of Chile, Argentina, Bolivia, China, and Tibet.

The most famous area for lithium is known as the Lithium Triangle, located on the border between Chile, Argentina, and Bolivia. Salar de Atacama, the world’s third largest salt flat, resides on the Chilean side, and contains about 50% of global reserves.

The largest lithium producers in 2015 were Chile (37%) and Australia (33%). Argentina is the only other double-digit producer at 11%.

Lithium is Fueling the Green Revolution

Here’s the estimated amount of lithium that can be found in everyday items using lithium-ion batteries:

Tesla Model S: 51kg
Electric Vehicles: 10-63kg
Tesla Powerwall 2.0: 10kg
Hybrids: 0.8kg to 2.0kg
Power tool batteries: 40-60g
Laptops: 30-40g
Tablets: 20-30g
Mobile phones: 2-3g

Here’s Why the Amazon is So Important for Global Food Security

The Amazon rainforest plays a critical role in supporting crop growth by stabilizing the climate and balancing water cycles.

Why is the Amazon Rainforest Important for Food Security?

The Amazon rainforest is home to 400 billion trees and covers 6.7 million square kilometers, but the ‘Earth’s lungs’, as it is commonly referred to, is so much more than that.

Aside from being a key carbon sink, it also plays a critical role in supporting crop growth by stabilizing the climate and balancing water cycles.

In this infographic, our sponsor Brazil Potash looks at how the Amazon regulates rainfall and temperature and how crop yields can be optimized. Let’s dive in.

Rainfall as a Primary Water Source

Flying rivers” are air currents that carry enormous amounts of water vapor over thousands of kilometers. These airborne rivers are responsible for influencing regional and global weather patterns, including rainfall. 

The Amazon flying river cycle begins with water evaporating from the Atlantic Ocean. Wind currents then transport these vapors across the continent, exchanging moisture with the Amazon rainforest through evapotranspiration. Finally, these aerial rivers distribute the moisture as rain.

The trees in the Amazon rainforest release around 20 billion tonnes of water into the atmosphere daily—this is more water than the Mississippi River discharges in 13 months.

Because only around 6% of cropland in Brazil is irrigated, the region relies heavily on this rainfall as a primary water source to support crop growth that feeds both local and global communities.

Temperature Regulation

The Amazon also absorbs billions of tons of carbon dioxide (CO2) a year through photosynthesis. By absorbing this CO2, it helps regulate temperatures and lessen the effects of climate change.

According to NASA research, the cumulative effects of climate change, accelerated by deforestation, may result in the loss of up to 11 million hectares of agricultural land in Brazil by the 2030s. 

The continued sustainable production of Brazil’s crops is essential to food security, but deforestation can harm these efforts.

How to Grow More With Less

Brazil hosts the largest section of the Amazon rainforest at around 60%. The country is also one of the world’s largest exporters of agricultural goods. 

It’s essential for global food security and for climate change that crop yields in Brazil are increased in areas already allocated for agriculture, instead of clearing new areas in the Amazon rainforest. 

A recent study highlights a significant yield gap in Brazil’s primary export, soybeans.

A yield gap is the difference between actual crop yield and potential crop yield.

Cerrado62%38%
Amazon69%31%
Atlantic Forest76%24%
Pampa92%8%

The following steps proposed could optimize land usage:

  1. Increase crop yields: This can be done in part by optimizing and increasing fertilizer use. Local fertilizer suppliers are essential to this by providing affordable and accessible fertilizer year-round.
  2. Double Crop: Continuing to grow a second crop of corn on soybean fields between seasons to optimize land usage. Additional fertilizer is essential to maintain the soil’s nutrients after harvests.
  3. Raise cattle on smaller pastures: By streamlining the space provided for cattle, additional cropland can be added to support food for both people and livestock.

The Role of Brazil Potash

Brazil Potash aims to support the preservation of the Amazon rainforest by working with farmers to increase crop yields and improve the quality and quantity of food grown, without the need for land expansion.

By keeping farmers informed of fertilizer’s benefits and supporting a more stable supply of local fertilizer, Brazil Potash will continue supporting farming communities for generations to come.
