I thought nickel-colbalt has a significantly lower specific energy / energy density than other lithium-polymer batteries. They might be cheaper to make (or maybe not so much anymore), but they have a large space form factor.
I don't know of any laptop today that's using a nickel cobalt battery. Those ones usually allowed you to remove the battery pack from the laptop. Now there all based on lithium-polymer now. Same with smartphones.
I did some research in lithium polymer batteries a few years back. I distinctly remember there being almost 10 or so variations of lithium polymer mixes being used in battery production.
- hwillis 8y agoNo, LiPo (which really means li-ion with gel or polymer electrolyte) has a lower specific energy (kWh/kg) but higher specific power (kW/kg). > I don't know of any laptop today that's using a nickel cobalt battery. Those ones usually allowed you to remove the battery pack from the laptop. Now there all based on lithium-polymer now. Same with smartphones. They all use NMC (nickel manganese cobalt) cathodes. LiPo batteries have the exact same cathodes and anodes as normal li-ion, just a different electrolyte. > I did some research in lithium polymer batteries a few years back. I distinctly remember there being almost 10 or so variations of lithium polymer mixes being used in battery production. There are ~10 main chemistry families, but hundreds of mixes.
