Lithium Ion (Li-ion) Batteries

Li-ion battery chemistries are proprietary to their manufacturers. Predominant chemistries are lithium cobalt oxide, which offers high energy density but can be dangerous if damaged; lithium iron phosphate; lithium ion manganese oxide, and lithium nickel manganese cobalt oxide. Li-ion battery manufacturers are primarily based in Japan and China. They manufacture Li-ion batteries for consumer and industrial purposes. Most of these companies are partnered with car manufacturers to ensure a supply of Li-ion batteries for hybrid and electric vehicles. Factors driving Li-ion innovation are battery life, energy density, safety, cost reduction, and charging speed.

Designed to power longer-range, lower-cost, safer electric vehicles,Designed to be safer,offer higher energy and cost less than lithium-ion.


There are several types of rechargeable storage battery techonologies available including standard flooded, absorbent glass mat (AGM), etc. How batteries are used and how power systems work influence what battery technology is best for you.

Our solution

Solid Power’s Sulfide-Based Solid Electrolytes

Powering Solid Power’s platform technology

Solid Power’s all-solid-state batteries remove the flammable liquid electrolyte and polymer separator layer in a traditional lithium-ion battery and replace it with a solid layer. This thin, solid layer acts as a barrier to keep the anode and cathode from touching one another, which would short the battery. It also acts as a conductive electrolyte.

Solid Power’s sulfide-based solid electrolyte is the key ingredient that powers Solid Power’s All-Solid-State Battery Platform technology. Solid Power’s electrolytes offer the best combination of conductivity (the ability to move ions back and forth quickly), manufacturability and cell-level performance.
