What does the future hold for Lithium Iron Phosphate (LiFePO4) Battery Technology?

Updated: Mar 15, 2021

EV market Shares with the more Affordable LFP, LMFP, or LMP Batteries continues to Grow.

The LFP Blade battery powered Hans, buses, trucks, and other auto EVs are commercial successes value & performance and gaining momentum with plans to export into key markets. Tesla offers a lower cost LMFP battery powered model 3 with the battery cells supplied by CATL in China and is already exporting into Europe. Xpeng offers lower cost LFP or LMFP battery powered models in China and will export into Europe. The very success and very affordable SAIC – GM Mini sold in China is powered by Lithium Metal Polymer (LMP) batteries.

The drop-in LFP batteries for replacing lead-acid batteries in RV, golf carts, boats, solar systems plus storage, fork lifts, etc. dominates this business sector. The emerging electric Purpose-Built-Vehicle (PBV) market that includes construction equipment, farm equipment, ranch equipment, ATV, UTV, shuttle vehicles, urban & regional cargo vans & trucks, etc. is well suited for LFP & LMFP.

The LFP batteries are growing markets share in the global EES business sector as shown by the Powin Corporation utility scale ESS which uses CATL battery cells. Several companies in China or expanding or building new LFP battery cell factories which will increase global market share from 20% in 2020 to 25% in 2021. The more affordable LFP batteries that require no strategic metals are well suited for the electrification of developing countries.

New Low-Cost Lithium Metal Polymer (LMP) Battery being used in the very Low Cost SAIC – GM EV in China

The SAIC – GM Mini is a very cheap EV made and sold in China that uses a LMP battery with an estimated 100W/kg energy density. Better than the ~45W/kg energy density for lead-acid and the LMP has better life and lower maintenance.

Ford CEO is encouraging LG Energy Solutions and SK Innovation reach a settlement as the best option for workers and auto companies. LG Energy Solutions may or may not accept a reasonable cash settlement. Editor mentions other options as sale factory or President Biden reversing the ITC decision.


Tax credits for electric vehicles in the United States

Bill introduced in Congress; “Growing Renewable Energy and Efficiency Now (GREEN) Act”, to reform the federal EV tax incentives, among other tax programs to help. Optimist that bill will pass since Democrats control house, senate, and Whitehouse. In short, automakers that have met the 200,000 EVs threshold already would have access to a new $7,000 tax credit for 400,000 additional electric vehicles until a new phase-out period starts again. Big plus for Tesla and GM. For other car companies that have not reached 200,000 EVs the new phase down of the $7,000 tax credit starts at 600,000 EVs. As the bill stands, the tax credit is not retroactive so some Tesla & GM buyers may postpone an EV purchase until bill passes.
