Overcoming Supply Chain Challenges to Global Electrification

Electrification—whether in cars, ships, or grid-scale storage—is one of the most transformative industrial shifts of our time. But behind the momentum lies a critical vulnerability: the world’s heavy reliance on China for the battery supply chain.

China refines the majority of the world’s lithium, cobalt, and graphite, and produces over 70% of all lithium-ion cells. Beyond raw materials, it dominates the integration of these cells into modules, packs, and containerized energy storage systems.

This control gives Beijing a lever as powerful as oil was in the 1970s. A disruption—political, logistical, or environmental—could bring electrification programs across continents to a standstill.

Fragility Exposed

Recent events show how fragile the system already is:

• CATL’s Jianxiawo mine suspension rattled global markets overnight.
• Houthi attacks in the Red Sea disrupted shipping routes, delaying the flow of both raw materials and finished systems.

In a supply chain dominated by a few players, even minor interruptions can have outsized consequences.

Where the Risks Hit Hardest

• Automotive: EV makers are tethered to Chinese suppliers. Disruptions could delay launches, inflate costs, and undermine consumer trust.
• Marine: With IMO decarbonization rules accelerating, shipowners depend on certified marine battery systems—most of which are China-dependent. Supply breakdowns could stall compliance and green shipping goals.
• Power & BESS: Utilities worldwide are racing to deploy Battery Energy Storage Systems (BESS) to stabilize grids and integrate renewables. However, most BESS units are manufactured directly in China. If supply halts, so will the adoption of renewables and grid modernization.

Why This Reliance Is Dangerous

The risks go far beyond cost. A geopolitical crisis, sanctions, or environmental restrictions could cut supply overnight. EV adoption might grind to a halt. Marine electrification could remain stuck at pilot scale. Renewable energy projects could stall without the storage backbone they need.

Carrar’s Approach: Getting more energy from fewer batteries

At Carrar, we take a different path. Our proprietary two-phase immersion thermal architecture ensures batteries operate at optimal conditions—regardless of chemistry, climate, or load.

The impact is measurable:

• Longer-lasting batteries with higher states of health
• Greater lifetime energy throughput from the same cells
• Reduced need for augmentations and replacements
• Lower total cell demand per project

By enabling OEMs and utilities to get more energy from fewer cells, we directly ease pressure on fragile global supply chains.

The Path Forward

Electrification cannot hinge on the output of a single country. Diversification, recycling, and new mining are all essential. But just as vital is ensuring every battery cell is used to its fullest potential.

Carrar’s technology helps industries reduce exposure to chokepoints by extending battery life, improving efficiency, and lowering total cell demand.

The clean energy transition depends not only on cell innovation but also on smarter system design. At Carrar, we believe battery longevity and throughput are just as critical as chemistry. By reducing supply chain risks to the global electrification sector, we help build a more resilient and sustainable pathway to global electrification.
