How to Harness Surge in Demand for Electric Cars

Electric car sales increased by 37% in 2016, according to Forbes magazine.

In January 2017 alone, electric car sales rose by 59%.

As consumer demand for electric cars increases, so does the demand for the lithium ion batteries that power them. There’s also an increase in the number of cells within the battery (to increase the range per charge). 

Extreme precision is the key to producing lithium ion cells. The science of conductivity, potential safety hazards, rising costs of materials and the number of components working together leave no margin for error.

If anode, cathode and electrolyte layers are inconsistent, resistance will impede the flow of energy. Simply stated, the flow of electrons and discharge of energy slows or stops.

The Costly Risk of Inconsistent Thickness

Even the smallest variation in layer thickness can cause a buildup of heat, and possibly cause a fire. Typically, each layer of anode, cathode and electrolyte needs to be produced with rolls at a tolerance as small as 40 millionths of an inch. Anything more or less has the potential to reduce the effectiveness or result in a failure which may harm both employees and end users.

Lithium Ion Battery Material Costs Are also on the Rise

68% — that’s how much of an increase Automotive News projects for cobalt consumption through 2025. You won’t have to wait a decade to see the effect on cost. Since December 2016, cobalt prices have risen 63%, from $30,000 to $49,000 per metric ton.

Cost-Efficiency Through Your Rolls’ Condition

The condition of the rolls used to create anode, cathode and electrolyte layers is critical to cost-effective production of lithium ion batteries. Perfectly ground rolls with exact concentricity will:

  • Help guarantee an effective product.
  • Keep both employees and end users safe.
  • Prevent costly waste of materials.
  • Protect your business’ reputation and bottom line.

Succeed with Precision

No U.S. roll grinding service besides Precision Roll Grinders is equipped to achieve the tight tolerances — up to 40 millionths of an inch — required for lithium ion cell production. Roll defects, loss of roundness or other issues will affect your product and your bottom line. Contact us for a free, on-site consultation at your location.
