Potassium-ion batteries are modern energy storage devices. K-Plus develops a technology for a full production cycle of the next-generation, post-lithium-ion batteries. These batteries are cheap, reliable, and energy-efficient. The project is between TRL 4 and 5.

Technology scope:
Stationary energy storage and electric transport for short distances (logistics vehicles, electric buses, uninterruptible power supplies, energy storage for renewable sources).
Competitive strengths:
— thanks to widespread reserves of potassium, cheap components are used to produce a battery cell, and it leads to 1 kilowatt-hour saved in the potassium-ion battery to be cheaper than in the lithium-ion battery;
— key components are manufactured in Russia;
— safety — batteries consist of nonflammable and nontoxic components.

Market in Russia and competitors:

The potential market of stationary energy storage in Russia is estimated at $1 billion with an annual increase of 5-8%. Among the alternatives such as lead-acid, lithium- and sodium-ion batteries, potassium-ion battery has great advantages. Namely, the energy density, durability, and utility of lead-acid batteries are low, and sodium-ion batteries are not available yet, and they are mostly an imported technology. Despite their high energy density and widespread use, lithium-ion batteries can be hazardous and expensive, especially for stationary energy storage that requires a significant amount of costly lithium-based materials. Potassium combines all the advantages of these technologies, such as price, reliability, utility, safety, and energy density. The production of potassium-ion batteries can be started anywhere in the world, including Russia. K-Plus is the first company in the world to publicly announce the commercialization of potassium-ion batteries in 2020.
