UK-based OXIS Energy UK has announced it expects to achieve 450Wh/kg at cell level on its lithium sulfur (Li-S) cell technology by the end of 2018, the company said.
The company said it aims to reach 500Wh/kg by the end of 2019 through its many collaborations and partnerships. OXIS said it has already achieved 425Wh/kg on a High Energy 16Ah pouch cell design for HAPS applications (High Altitude Pseudo Satellites).
The company said the cell is about to go into prototype applications and is already attracting interest from major players in the aerospace sector.
OXIS has also developed a prototype battery module for the aviation sector which has enabled OXIS´ customers to increase flight time three-fold. The battery module uses a High Power, Ultra-Light Lithium Sulfur pouch cell at 300 Wh/kg. Future modules will tap into the increasing capabilities of Lithium Sulfur pouch cells, where High Power cells are forecast to achieve 400 Wh/kg by 2019.
OXIS Energy Ltd is involved in the design, development and now the move towards commercial production of lithium sulfur cells for battery systems. With 39 patent families, OXIS has been granted 141 patents with 108 pending.
