Simple Liquid Batteries (SLB)

SLB offers ecofriendly, safe and easily device for greater power generation


Increasing energy demands worldwide and a depletion of fossil fuel resources require general science and specifically physics to develop alternative sources of energy for daily usage. Simple Liquid Battery (SLB) presents an ecologically clean, non-hazardous and non-toxic device for solving various household problems.

We offer (relatively) cheap and portable battery banks which function based on almost any type of household liquid, such as saltwater, buttermilk, vinegar, tea, coffee, beer, rainwater and so on. Our proposed device is simple in usage: just add any of the liquids that the device supports and through hazardless chemical reaction you will get the required energy.

One of the key advantages of our SLB are its small size, portability and energy efficiency. This product will be your inseparable companion in camping, hiking, trips and flights, the household and, importantly, emergency situations.
