New and Sustainable Lithium Solutions for Solid-State EV Batteries

Electric vehicles (EVs) are becoming increasingly popular as a sustainable transportation option. However, their lifespan and the environmental impact of their batteries have raised concerns. Currently, EV batteries need to be replaced every 10-20 years, resulting in a significant carbon footprint from the production and disposal process. To address this issue, EnergyX, a startup focused on sustainable lithium solutions, is making strides in developing longer-lasting, solid-state EV batteries.

EnergyX is working on a project called “Simplified High Purity Direct Lithium Hydroxide Production from Salton Sea Brines,” which received $5 million in funding from the US Department of Energy. The aim is to extract lithium from geothermal brine to create a more environmentally friendly battery.

Additionally, EnergyX has developed the LiTAS™ DLE Platform, an integrated Direct Lithium Extraction system that optimizes renewable energy from geothermal operations. This system combines multiple technologies, such as Adsorption (AX), Solvent Extraction (SX), and Selective Membranes (MX), to create an efficient and robust lithium production process.

In terms of battery technology, EnergyX is also making progress in the development of solid-state EV batteries. Compared to conventional liquid electrolyte batteries, solid-state batteries offer benefits such as longer lifespan, better range and charging performance, and lower costs. EnergyX’s proprietary SoLiS electrolyte, still in the development phase, has shown a lifespan of over 600 cycles, with a goal of exceeding 1,000 cycles. These solid electrolytes also have high conductivity and are cost-effective and simple to process.

Not only would these longer-lasting solid-state batteries enhance the lifespan and performance of EVs, but they would also significantly reduce the carbon footprint associated with battery replacements. EnergyX estimates that a solid-state lithium metal battery derived from their technology could power an electric vehicle for about 500,000 miles and 600+ miles per charge. This advancement would make EVs more affordable and accelerate the transition to green energy.

While solid-state batteries are a crucial component of a sustainable EV future, the recycling of these batteries is equally important. The Department of Energy’s Lawrence Berkeley National Laboratory is actively researching recycling-friendly approaches to solid-state battery technology, ensuring that the batteries’ sustainable materials are efficiently recycled.

In conclusion, EnergyX’s innovative solutions in lithium extraction and solid-state battery technology are propelling the EV industry towards a more sustainable future. By developing longer-lasting batteries and focusing on recycling solutions, EnergyX is reducing the environmental impact of EVs and accelerating the transition to cleaner transportation.
