Lithium-titanate (LTO) is an interesting battery chemistry that is akin to Li-ion but uses Li2TiO3 nanocrystals instead of carbon for the anode. This makes LTO cells capable of much faster charging and with better stability characteristics, albeit at the cost of lower energy density. Much like LiFePO4 cells, this makes them interesting for a range […]
Lithium technology has ushered in a new era of batteries with exceptionally high energy density for a reasonably low cost. This has made a lot possible that would have been unheard of even 20 years ago such as electric cars, or laptops that can run all day on a single charge. But like anything there […]
There are a lot of things that get landfilled that have some marginal value, but generally if there’s not a huge amount of money to be made recycling things they won’t get recycled. It might not be surprising to most that this is true of almost all plastic, a substantial portion of glass, and even […]
Electric scooters have long been a hacker’s friend, Xiaomi ones in particular – starting with M365, the Xiaomi scooter family has expanded a fair bit. They do have a weak spot, like many other devices – the battery, something you expect to wear out. Let’s say, one day the scooter’s diagnostics app shows one section […]
Remember when dead batteries were something you’d just toss in the trash? Those days are long gone, thankfully, and rechargeable battery packs have put powerful cordless tools in the palms of our hands. But when those battery packs go bad, replacing them becomes an expensive proposition. And that’s a great excuse to pop a pack […]
