Base paper boosters can be equipped with different types of batteries, and the materials of these batteries are different, which will directly affect the performance indicators of the booster, such as energy density, weight, cost, cycle life and safety. The following is a comparison of several common battery materials:

6. Total Cost of Ownership Analysis
def calculate_tco(initial_cost, cycles, energy_per_cycle):
cycle_cost = initial_cost / cycles
energy_cost = energy_per_cycle * electricity_rate
return cycle_cost + energy_cost
# Example comparison (USD)
liion_tco = calculate_tco(150, 1000, 0.2) # $0.35/cycle
lto_tco = calculate_tco(500, 15000, 0.22) # $0.07/cycle
7. Safety Protocol Requirements
| Technology | Mandatory Protections | Thermal Runaway Onset |

| LTO | None required | Not applicable |
| Solid-state | Pressure relief valves | >400°C |
Conclusion
For base paper booster applications requiring >5kW power and 8+ hour runtime, lithium titanate batteries currently offer the optimal balance of performance and durability. Environmentally conscious operations should consider paper battery hybrids for auxiliary systems, while high-precision applications may await commercial solid-state solutions. Lithium-ion remains cost-effective for moderate-use scenarios, provided proper battery management systems are implemented. Future advancements in solid-state and bio-batteries promise to reshape this landscape within 5-7 years.
