What’s in an EV battery?
Fortune favours the fold. Folding led to origami, one of the world’s most unique and celebrated art forms. It also sees use in EV batteries, folding modules to maximise storage while taking up minimum space. Because naturally, EV batteries contain more than the battery modules themselves.
Given that batteries take centre stage in the electric mobility revolution, it’s natural to wonder what they’re made of. A battery pack contains two main components: battery cells, and a Cell-Module Controller (CMC) which controls all information and functions of the battery like voltage, current, and temperature by controlling the CMC and other parts.
The cells themselves are made up of cathodes, anodes, separators, and electrolytes. The folding begins by stacking the cathode, anode, and a separator together. In a mixing process, the raw materials are combined and used to coat copper and aluminium foil to ensure proper electric flow within the cell.
Cells are packaged differently. Prismatically, in a pouch, or as a cylinder. Each type has some strong and weak points when it comes to productivity, cost, and safety.
Folding opens up new avenues, both in the arts and in battery technology. Proving conclusively that a fold move is the right move.
Beyond the Road: Hannah Catmur
Welcome to Polestar Beyond the Road. In this new content series, we will meet Polestar owners from around the world to explore their stories. First up is tech aficionado Hannah Catmur. From pitching apps to Tim Cook to travelling through the South American jungles, her story is one worth telling.
Is Quiet Luxury the next big thing in mobility?
You may have seen it on your TV screens recently. Your favourite fashion influencer has probably enthused about it on TikTok. Or maybe you've read one of the countless editorials that litter the lifestyle pages of glossy magazines. Unknowingly or not, the latest trend taking over the fashion industry has almost certainly touched your life. But dig a little deeper and you start to discover two things. Firstly, this trend isn't just limited to the fashion world. And secondly, it's not really a trend at all. Welcome to the wonderfully rarefied world of quiet luxury.
Four things you didn’t know about Polestar (but wished you did)
We’re not one to toot our own horn. So we won't. We won't tell you how we've manufactured 150,000 Polestar 2s. We won't get into brand growth and vehicle registrations. And we certainly won't mention our ever-growing global retail footprint that has resulted in over 20,000 handovers in the United Kingdom alone. No. We'll leave the PR to the press people. Instead, as others celebrate these milestones, we'll focus on some of the human (and not-so-human) stories behind the numbers. Because Polestar isn't just about cars. It's about people.
