Energy storage solid-state battery buyback program

What is a solid-state battery (SSB)?

The solid-state battery (SSB) is a novel technology that has a higher specific energy density than conventional batteries. This is possible by replacing the conventional liquid electrolyte inside batteries with a solid electrolyte to bring more benefits and safety.

What is a battery energy storage system?

Battery Energy Storage System (BESS): Battery Energy Storage Systems, or BESS, are rechargeable batteries that can store energy from different sources and discharge it when needed. BESS consist of one or more batteries. Personal Mobility Device: Potable electric mobility devices such as e-bikes, e-scooters, and e-unicycles.

What is a solid-state battery (ASSB)?

All solid-state batteries (ASSBs) are an emerging type of Li-ion technology that holds the promise of increased energy density and safety. In an ASSB, the liquid electrolyte and polymer separator is replaced with a solid electrolyte.

Are solid-state batteries safer than Li-ion batteries?

Recent research has indicated that solid-state batteries may be less safe than Li-ion batteries under short circuit failure because their higher energy density means that the same amount of heat is released in a smaller mass and volume, leading to higher temperatures.

What is the energy storage system subsidy policy?

The plan focuses on PV cells and fuel cells. March 2011: after the earthquake, the government allocated 1.51 billion yen for energy storage technology including fuel cells, energy trading system and battery to improve energy consumption rate. April 2012: family energy storage system subsidy policy was proposed.

What's new in energy storage safety?

Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.
