HOUSTON, 4 August 2023: Zeta Energy has initiated extreme temperature testing of its lithium-sulfur batteries as part of the ARPA-E EVs4ALL project. The company was awarded USD 4m in federal funding to develop efficient electric vehicle batteries, focusing on reducing recharging time, enhancing low-temperature performance, increasing energy retention, and lowering battery costs.
Zeta Energy’s breakthrough lithium-sulfur battery technology shows promising results, exceeding project targets and supporting the development of a domestic supply chain for advanced battery production.
Progress in High Density Electrodes
Zeta Energy has made significant progress in constructing very high-density electrodes, surpassing the initial project targets. The company’s proprietary 3D-structured lithium metal anode, coupled with a sulfurized carbon cathode, is proving to be a winning combination.
Extreme Temperature Testing
The company is currently conducting extreme temperature testing on cells built from their advanced electrodes. Initial results show the batteries functioning efficiently at -20°C, with plans to extend testing to even lower temperatures.
Key Objectives of ARPA-E EVs4ALL Program
Zeta Energy’s participation in the ARPA-E EVs4ALL program aligns with four key objectives: reducing battery recharging time, improving low-temperature performance, enhancing energy retention after extensive use, and reducing battery costs to promote widespread adoption of electric vehicles.
Advantages of Zeta Energy’s Battery Technology
Zeta Energy’s proprietary 3D-structured lithium metal anode offers higher energy density while avoiding safety hazards and lifecycle issues associated with other lithium metal anodes. Paired with a sulfurized carbon cathode, the batteries exhibit outstanding stability, performance, and cost-effectiveness.
Supporting a Domestic Supply Chain
The use of widely available domestic feedstocks in Zeta Energy’s battery technology supports the development of a domestic supply chain for advanced battery production, contributing to US competitiveness in this field.
Zeta Energy’s progress in extreme temperature testing and the development of high-density electrodes demonstrates the potential of its breakthrough lithium-sulfur battery technology. By aligning with the ARPA-E EVs4ALL program objectives, Zeta Energy aims to drive the future of electric vehicle batteries, promoting sustainable and cost-effective solutions for widespread market adoption.
