Product Introduction

Lithium Metal (Li, CAS No. 7439-93-2) is a lightweight alkali metal and one of the most important advanced battery materials used in next-generation energy storage technologies. Due to its extremely low atomic weight, high theoretical specific capacity, and very negative electrochemical potential, lithium metal is widely investigated as a high-energy-density anode material for lithium metal batteries and solid-state batteries.

Compared with conventional graphite anodes, lithium metal offers a much higher theoretical capacity (3,860 mAh/g) and lower electrochemical potential, making it a key material for developing high-energy-density rechargeable batteries, including lithium metal batteries, all-solid-state batteries, and advanced energy storage systems.

Lithium metal is also widely used as a reducing agent in organic synthesis and as a raw material for preparing organolithium compounds.
