What is a lithium battery?
Lithium batteries are a class of batteries that use lithium metal or lithium alloys as the positive/negative electrode materials, along with non-aqueous electrolyte solutions. In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis.
Lithium batteries are a class of batteries that use lithium metal or lithium alloys as the positive/negative electrode materials, paired with non-aqueous electrolyte solutions. The concept of lithium-metal batteries was first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham introduced and began researching lithium-ion batteries. However, due to the highly reactive chemical properties of lithium metal, its processing, storage, and usage place extremely high demands on environmental conditions. Thanks to advancements in science and technology, lithium batteries have now become the mainstream choice.
Lithium batteries can be broadly categorized into two types: lithium-metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium in its metallic state and are rechargeable. The fifth-generation product among rechargeable batteries, the lithium-metal battery, was introduced in 1996. It outperforms lithium-ion batteries in terms of safety, specific energy density, self-discharge rate, and cost-performance ratio. However, due to its inherently high technical requirements, only a handful of companies in a few countries currently produce lithium-metal batteries.
