About Us

Polarium provides energy storage solutions for the telecom, commercial, and industrial segments.

Polarium Enables Endless Energy

Polarium, formerly Incell International, is a Swedish company dedicated to providing the best-performing, safe, and sustainable energy storage solutions built on lithium-ion technology.

We believe in a world of endless energy – a world where energy no longer comes from finite sources, where all energy is renewable, and the flow of energy never stops. We believe that this is within reach, but to get there we need great energy storage. And lots of it. Fast.

Since 2015 we are on a mission to create the best energy storage solutions in the world. With headquarters and R&D in Sweden, manufacturing in Mexico and Vietnam, and sales offices on all continents, we serve customers worldwide. Today, our market-leading solutions are in use on all continents and in all climate zones – from the Equator to the Arctic.

We enable our customers to move away from fossil fuels to long-lasting, smart, and recyclable lithium batteries – reducing costs as well as environmental impact.

We are driven by innovation and cutting-edge technology, resulting in advanced technology made easy to use. Our energy storage solutions are superior in quality, recyclable, certified and designed with the highest safety in mind. The embedded intelligence of our lithium batteries puts you in charge and minimizes maintenance.

Our Technology

Our technology lets you focus on your core business and save money whilst reducing your carbon footprint. We always strive to be one step ahead, by constantly improving our energy storage solutions to find new and innovative ways to solve your pain points.

Our Milestones

2021

Continued Growth

Polarium was ranked as the fastest growing company in the Nordics in Financial Times’ yearly list FT1000. We continued to sign large contracts in the telecom segment and sold our first products in the commercial and industrial segment. We opened a new factory in Vietnam and announced the establishment of another factory in South Africa, which were important steps in strengthening our global supply chain. Our strong focus on product development remained, and we released our Green product range.

2020

Expanding our Offering

In 2020, we launched our new company name – Polarium – and we expanded our offering from lithium-powered backup solutions exclusively for the telecom segment, to energy storage solutions for the commercial and industrial segments as well.

2019

An Industry Leader

Generation five of the Smart Lithium Battery series was released, and we certified our first products to UL standards for the US and Canadian markets. We signed additional large contracts and received our first large product order from Asia, which was installed the same year. Polarium, then known as Incell International, was increasingly recognized as the leader in lithium batteries for telecom.

2018

New Factory

We certified and released fourth generation of our Smart Lithium Battery products and signed new, exciting contracts. Our global expansion continued by opening a factory in Guadalajara, Mexico, which produced extraordinary volumes. Our sales organization was expanded with a new office in the UK and we also opened our Jakarta office to service Asia and the Pacific region.
In 2018, we received our first patent and became ISO certified.

2017

Global Expansion

We released the third generation of our Smart Lithium Battery series, ISO certified our products, and we signed our first global contracts.
We opened production in Stockholm, Sweden, and started volume deliveries. We added a sales office in the US among other locations, and the first Smart Lithium Power products were delivered to the Philippines.

2016

Our First Projects

We sold our first projects and installed out first products. We created the first generation of Smart Lithium Batteries, a product range today named Battery, and signed our first contracts.

2015

Polarium Is Founded

Polarium, at the time Incell International, was founded by Stefan Jansson in Stockholm, Sweden. The business idea was to combine power and batteries for the telecom industry, with a focus on the new 5G architecture for the city cell sites of the future. In order to jump-start the business and drive the evolution from lead to lithium, we signed an agreement with Incell Korea to evolve their telecom product portfolio. Our focus in 2015 was to develop generation one of Smart Lithium Power, a product range today simply named Battery + Power.

Our Superpowers

Safe

Our first priority is, and will always be, safety. All our products are designed with your safety in mind - thoroughly verified and certified for safe operation. We have a completely redundant safety system in the BMS, including electronically controlled circuit breakers, thorough control in the design and manufacturing of every system component to ensure safe operation. We also have advanced solutions for propagation prevention. The battery is protected during transportation, installation and use, even in the toughest conditions. Polarium is safe every step of the way.

Simple

In a few simple steps you are good to go. Advanced technology made super easy to use, allowing you control without obstacles. Easy installation and zero maintenance – just connect the cables and turn on power. Our products are plug-and-play compatible with existing power systems thanks to our patented charge control function. Configuration and testing are automatic. Polarium’s solutions are designed to support a wide range of deployment configurations and integration partners, with both low and high voltage battery systems.

Strong

We have installations in more than 60 countries, from the equator to the Arctic. Our products are strong, robust and of superior quality with a guarantee to provide a long-lasting life. They just keep working, even in the most extreme conditions and environments. The robust design includes optional ingress protection of the electronics. A wide range of lithium cell chemistries targeting different site conditions make our offering stronger than any other alternative in the market.

Smart

Thanks to the embedded intelligence of the lithium batteries, you will always know the state of charge (available capacity in real time) and the state of health (available life for optimal planning and usage). With a remote management system, the lithium power backup solution is maintenance free and you are in full control. You can also manage your on-site climate control system based on the internal temperature of the lithium battery or you can choose to shut down non-prioritized loads. All in all, with the smart information already embedded in the lithium battery you can gain control, plan better, save cost, and reduce the environmental impact.

Secure

You can feel secure, knowing that your Polarium solution is protected. Lead-acid batteries are stolen in many parts of the world due to scrap metal value, private usage, or re-sale back into the market. With Polarium’s lithium battery modules, the first two reasons for theft are eliminated. To address the last issue, we have developed multiple anti-theft features for our batteries, which completely prevents discharge of the battery module if removed from the installation. In addition, the batteries are prepared for our optional GPS tracker and marking alternatives, for recovery in case of theft.

Sustainable

Polarium’s lithium batteries are fully recyclable and meet all the RoHS, WEEE and REACH requirements. Also, the energy turn-around losses are only a few percentages, which is superior compared to other lithium batteries (normally up to 5%) and lead-acid (normally up to 30%). Every solution and product are made to have an extraordinary long lifetime and designed to stand the test of time. Our low carbon manufacturing and installation, efficient operation and the fact that our products are recyclable – all contributes to a circular business model.
