EA Group subsidiary Amita teams up with Taiwan’s ITRI to develop innovative solid-state batteries


Amita Technologies, Inc has successfully developed state-of-the-art solid-state batteries called NAEPE, or Networked-Amide Epoxy Polymer Electrolyte, with the Industrial Technology Research Institute of Taiwan (ITRI), Energy Absolute Public Company Limited (EA) announced in a press release.

Amita, a subsidiary of EA Group, has already bagged the 2020 R&D 100 Technology Award, well recognised as “the Oscars of Innovation”.

Clean energy use and the reduction of carbon dioxide emissions are now ingrained in the consciousness of all countries. Therefore, the introduction of renewable energy storage systems and the promotion of electric vehicles are being unanimously implemented by governments, automakers and enterprises across the globe.

The most critical strategic component of this is the lithium-ion battery.

“Whoever has a higher energy density battery with lower costs and higher safety will control the development trend of the latest wave of safer lithium battery technology,” the company explained.

“All-solid-state batteries are a goal everyone is striving for. However, stable and large-scale production of solid-state electrolyte materials and all-solid-state batteries have many bottlenecks that need overcoming in the current manufacturing process, which can reduce the production cost of batteries and increase the yield rate,” it said.

Now, with the introduction of NAEPE electrolyte, the design of the battery cell structure of Amita’s future lithium batteries is based on higher safety, higher conductivity and higher stability and reliability, the company said, adding that the battery’s interior resistance as well as the risk of becoming flammable will be greatly reduced.

In addition, NAEPE provides unique advantages to support lower costs, a longer life cycle and achievable development in fast-charging batteries.

NAEPE's self-protection also allows the battery to maintain the original characteristics of rapid charge and discharge and has significantly improved the battery's resistance to overcharged voltage and performance in a high-temperature environment.

The newly designed batteries can be quickly charged to 80 per cent of their capacity in just 15 minutes.

“Most importantly, unlike other solid-state electrolytes developed by top R&D battery players, NAEPE in the first phase as a quasi-solid-state electrolyte can be easily introduced into existing battery production processes by fast implementation of adding a few pieces of equipment in Amita’s 1GWh battery plant in Thailand,” the company said.

EA and Amita are now considering even further development and adoption of NAEPE, which is likely to be next year.
