Kalang lang, galaw shapraw ai ni gaw, bungli galaw ai lam hta pat shingdang ai lam ni hpe madun dan ai "usable energy density" hpe masat da ma ai: battery a prat galu na matu, n law htum charge hpe hkan sa na, shim lum na matu voltage hpe shadawn sharam tawn da na, nbung katsi ai hpe gram lajang na matu capacity derating galaw na. Laksan lang mai ai n-gun atsam gaw, theoretical maximum a 80-90% du hkra rai nga ai.

Hpaga lam lam madun laika hte 2025-2030 yaw shada lam ni

Asuya hte hpaga lam a yaw shada ai lam ni

Miwa mungdan a 2030 ning na battery lam masat masa hta 500-700 Wh/kg n-gun n-gun hpe yaw shada ai rai nna, n-gun n-gun n-gun n-gun n-gun hpe n-gun n-gun n-gun n-gun n-gun (lithium-ion) hta lai nna, n-gun n-gun n-gun n-gun hpe ra sharawng ai. Amerikan N-gun Hkringmang Dap gaw 2028 ning du hkra 350 Wh/kg hte 2035 ning du hkra 500 Wh/kg ngu ai yaw shada lam hpe masat da ai.Japan hte Dingda Korea mungdan ni mung dai zawn re ai n-gun ja ai yaw shada lam ni hpe solid-state hpaji masa kungkyang wa ai ngu sawn la ai.

2025 ning du wa ai shaloi, madung galaw shapraw ai battery ni gaw cell madang hta 300-330 Wh/kg du ra ai. RMI gaw 2030 ning du hkra 600-800 Wh/kg hpe top-tier hpaji masa a matu tau hkrau tsun da ai, raitim ndai gaw awng dang ai solid-state hpaga lam hpe shadawn shadang hku sawn la ai.

Hpaji masa aten masat

2024 ning hta 280300 Wh/kg du hkra galaw shapraw ai Silicon battery ni hpe law law lang galaw shapraw hpang wa sai. 350-400 Wh/kg rawng ai semi-solid-state battery ni hpe manu dan ai mawdaw ni a matu shadawn sharam sha galaw hpang wa ai.

2026-2027: 400-450 Wh/kg n-gun rawng ai shawng ningnan lang na solid-state battery ni hpe manu dan ai mawdaw ni hta manu dan ai hku nna shapraw na re. 320-340 Wh/kg hta n-gun rawng ai NMC 9-0.5-0.5 n-gun rawng ai n-gun rawng ai lithium-ion gaw, n-gun rawng ai lithium-ion byin wa ai.

2028-2030: Lahkawng ngu na-prat na solid-state battery ni hpe 500+ Wh/kg scale up galaw shapraw ai lam du wa na re. Lithium-sulfur hte lithium-nbung battery ni gaw laksan jai lang ai lam (nbungli, hpyen masa) hta 600-800 Wh/kg hpe madun dan ai.

2030 ning a hpang: Rawt jat galu kaba wa ai solid-state hte lithium{2}}metal hpaji masa ni gaw, laksan jai lang ai lam ni a matu 1,000+ Wh/kg a theoretical shadawn sharam de du wa mai ai, raitim, madung hku hkap la ai lam gaw, galaw shapraw ai sut masa hta madung nga ai.

Galoi mung san ai ga san ni

Battery langai a matu kaja ai n-gun atsam gaw hpa rai ta?

Application gaw "kaja ai" n-gun atsam hpe dawdan ya ai. Hpa majaw nga yang, shingjawng ai arung arai ni a matu, jai lang ai arung arai ni a matu 250-300 Wh/kg ra ai. Wan jak mawdaw ni gaw 300+ mile tsan ai shara ni hta pack madang hta 200-250 Wh/kg ra ai. Grid shingbyi shara gaw shara hta manu grau ahkyak ai shaloi 100-150 Wh/kg hpe hkap la ai. Density grau tsaw ai gaw galoi mung akyu jaw ai, raitim hkap la mai ai minimum ni gaw lang ai masa hku nna n bung ai.

Battery a n-gun atsam gaw EV charge galaw ai aten hpe gara hku hkra machyi shangun ai kun?

N-gun atsam gaw charge galaw ai lawan ai lam hpe n hkrak ai hku hkra machyi shangun ai. Density grau tsaw ai battery ni gaw, maren mara atsam a matu cell n law ra ai majaw, jaw da ai charge rate ni a matu ra ai total current hpe shayawm ya lu ai. Raitim, n-gun ja ai electrode packing gaw lithium-ion shamu shamawt ai lam hpe pat shingdang ya lu ai majaw, lawan ai hku charge galaw ai hte n-gun ja ai n-gun ja ai lapran hta design tension ni hpe shabyin ya lu ai. Hpaga galaw ai ni gaw ndai lam ni hpe electrode a n-gun hpe grau kaja hkra galaw ai hte thermal hpe hkang ai hku nna rap ra hkra galaw ma ai.

Hpa majaw battery ni gaw wan sau a n-gun atsam de n du shi ai kun?

Hydrocarbon ni hta lawm ai chemical bonds ni gaw, battery ni hta byin ai wan n-gun n-gun hta grau nna, unit mass langai hta n-gun grau law hkra shinggyin tawn da ai. Gasoline gaw carbon hte hydrogen hpe 12,000 Wh/kg hta kayau kaya galaw nna, lithium{3}}ion a theoretical hku nna 1,250 Wh/kg grup yin hta kayau kaya galaw ai. Ndai shai hkat ai lam gaw npawt nhpang chemistry kaw na pru wa ai: wan hkru ai lam ni gaw CO2 hte H2O n-gun hpe hpaw shabawn ai kaw na n-gun hpe shapraw ya ai, battery ni gaw atomic-scale ion shamu shamawt ai hku nna n-gun hpe shinggyin tawn da ai. Battery hpaji masa gaw matut nna rawt jat wa nga ai raitim ndai chemical tengman ai lam hpe n dang dang lu ai.

Wh/kg hte Wh/L gaw hpa shai ai kun?

Wh/kg (gravimetric energy density) gaw n-gun unit langai hta n-gun hpe shadawn ai-n-gun gaw n-gun atsam hte bungli galaw ai lam hpe hkra machyi shangun ai htaw sa ai lam a matu ahkyak ai. Wh/L (volumetric energy density) gaw n-gun unit langai hta n-gun hpe shadawn ai-smartphone hte hkrunlam hkawm mawdaw ni hpe shinggyin ai zawn re ai shara n law ai application ni a matu ahkyak ai. Specification lahkawng yan gaw ahkyak ai, raitim, application n bung ai ni gaw langai hpe kaga langai hta grau ahkyak shatai ai.
