Artificial Intelligence is taking a deeper look into the problem of battery aging

Batteries degrade with age. Monitoring their condition is very important, but it is also kind of tricky.

The Vancouver-dependent organization was the initial to mass produce rechargeable lithium-metal batteries. But the batteries had a unpleasant behavior of exploding, which finally led to a massive recall that bankrupted the organization.

30 decades have handed, but today’s lithium-ion batteries are even now wont to blow up. 1 perpetrator is the liquid electrolyte, a commonly flammable natural and organic solvent that facilitates the flow of ions amongst a battery’s electrodes. Replacing this … Read More
