10 Key Differences Between Traction Batteries and Lithium-ion Batteries.
Chemical composition: Traction batteries are lead acid based while lithium ion batteries are solid lithium based.
Cycle life: Traction batteries have a lower cycle life than lithium-ion batteries. Traction batteries can last up to about 1000 cycles, while lithium-ion batteries can last up to about 3000 cycles.
Memory effect: Traction batteries have a memory effect, while lithium-ion batteries do not. The memory effect causes the batteries to store less energy and have a shorter life.
Weight: Lithium-ion batteries are lighter than traction fluxes. Therefore, lithium-ion batteries are more portable and easier to use.
Charging speed: Lithium-ion batteries can be charged faster, while traction batteries are charged slower.
Safety: Lithium-ion batteries are safer because explosion-causing gases cannot escape. However, traction batteries carry a risk of explosion and may release toxic gases.
Self-discharge: Lithium-ion batteries self-discharge less than traction batteries. Therefore, lithium-ion batteries can be stored for longer periods of time.
Efficiency: Lithium-ion batteries are more efficient than traction batteries and have a higher energy density.
Cost: Lithium-ion batteries are more expensive than traction batteries.
Maintenance: Lithium-ion batteries require less maintenance than traction batteries.
