· Li4 B4

Li₄B₄ is an experimental lithium borate semiconductor compound combining lithium and boron elements in a 1:1 ratio. This material belongs to the family of boron-based semiconductors and is primarily of research interest for advanced energy storage, optoelectronics, and solid-state device applications. While not yet established in mainstream commercial manufacturing, lithium borates are being investigated for their potential in next-generation battery systems, wide-bandgap semiconductor devices, and high-temperature applications where conventional semiconductors reach their limits.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
