Problem that lithium battery pack need to improved
Lithium-ion batteries represent a landmark technology that has made the current generation of electric vehicles possible. However,There has two technology question need to solved , Lithium-ion chemistries have a certain maximum energy density, and today’s batteries are not so far from that theoretical maximum. If drivers keep demanding longer ranges and faster charging times, then a better technology will have to be found.
Safety is also an issue. The spectacular explosions and fireballs that some documentary-makers revel in are not the norm (when was the last time your phone or computer caught fire?), but Li-ion batteries do have to be handled carefully, and necessary safety features add complexity and cost to battery packs. A new chemistry that is safer could also prove to be cheaper.
Researchers around the world are working on “beyond lithium” projects, and the past year has seen several significant breakthroughs. Of course, advances in the lab take years to make their way to the marketplace, but if and when one of these promising technologies can be commercialized, we could see game-changing improvements in the performance and cost of EVs.
